BOLTING AND INSTALLATION INSTRUCTIONS

ZP300 standard flange configuration is

“flanged” where port flange mounting holes are

drilled and tapped. Flange mounting holes in

chest area are limited to a depth of 1 x flange

bolt diameter. It is recommended that studs

be used on all flange mounting holes in chest

area.

WARNING

Care must be taken when installing studs or bolts

in tapped flange holes in chest area to prevent

damage to internal wall profile.

NOTE

Optional through bolting configurations are also

available.

ZP300 Series valves are design to suit flanges

compliant to ASME B16.5 and B16.47, and

gaskets designed to ASME VIII-1 Appendix

2, and ASME B16.20 and B16.21. Torque on

Flange bolt should not exceed values shown in

Table 1.

4. Packing assembly: the packing gland bolts

should be checked and adjusted to obtain

a first time packing seal. Packing gland

nuts may become slightly loose when valve

is shipped. Field adjustment is expected

and desired. (Figure 1. Tighten just enough

to stop any leakage. Overtightening may

increase valve operating torque and shorten

packing life).

* Face to face dimensions per MSS SP-135 long pattern

1. Examine entire valve and report any damage

or discrepancies immediately.

2. Accessories, if any, including solenoids,

limit switches, positioners, etc., are tested

for functionality prior to shipment. Examine

carefully for damage which may occur

during shipment.

3. Operators: standard manual hand wheels

may be shipped loose for field installation.

It is necessary to use a pipe wrench or large

crescent wrench to properly tighten the

hand wheel retaining nut. Be sure to fully

tighten.

2. Bevel gear lockout is standard for use on

BG actuators.

3. Lockout pin on both open and closed

positions standard on hydraulic cylinder

actuators

4. Lockout pin style for open and closed

positions are optional for MH valves.

5. Energy lockouts for hydraulic cylinder

actuators.

Safety

1. Pin-style lockouts will assume potential

energy of actuator has been removed

through other means and are designed

to prevent gate movement caused by

line pressure. They are not designed to

overcome or resist an energized hydraulic

cylinder actuator.

2. Pin-style lockouts positions will be designed

to resist unauthorized manual unassisted

operation of the valve and prevent gate

movement caused by line pressure.

3. Pin style lockouts not available on BG

actuated valves.

For sizes NPS 26 and above consult sales for detail

OPERATIONAL CONSIDERATIONS

operate due to torque requirements, it is

recommended that the valve be supplied

with or converted to a bevel gear, air/

hydraulic cylinder or electric motor

actuator.

6. Electric motor actuated valves should be

left in their factory set condition unless

the system operating parameters dictate

a change. If changes are necessary, they

should be performed in small increments

using the lightest/lowest setting possible

to achieve the desired performance and

then the valve/actuator function inspected.

Excess torque and/or thrust in the motor

settings may damage or lockup the valve.

7. The ZP300 valve is position seated and

should never be torque seated. Do not use

the motor torque settings to seat the valve.

8. Care should be taken to ensure that

electrical motors are wired correctly.

Incorrect phasing of 3-phase wiring may

cause valve/motor damage.

NOTE

Lockout design may vary between sizes. All lockouts

include a pin to secure lockout in position and lanyard

to tie lockout pin to valve body.

1. All valves should be operated within their

design pressure and temperature ranges.

Under no circumstances should the valves

be operated at conditions outside these

parameters.

2. The operator should have an understanding

of the effects of opening/closing the valve

with regards to its role in the overall piping

system. Take caution to ensure that the

valve is in good operating condition prior to

operating it under pressure.

3. Care should be taken when processes

contain hazardous and/or otherwise

unstable media to ensure the operator is

aware of the specific health and safety risks

associated with that medium.

4. Stand clear of any moving parts such as the

stem and/or gate assembly when operating,

use of gloves is suggested when operating

manual valves to minimize the risk of injury.

5. All manual handwheel operated valves

are designed for hand input. Do not apply

excessive input torque via pipe wrenches,

'cheater bars', or other devices. If a manual

handwheel actuated valve is difficult to

INSTALLATION AND MAINTENANCE INSTRUCTIONS

FLOW RING ROTATION

An external flow ring can be rotated three

times (3 x 90˚) after original installation. Four

ASTM A574 steel, zinc plated socket head

cap screws (SHCS) are required to position

a ring and compress an o-ring gasket that

seals the flow ring to the valve body. Sufficient

tapped holes are provided in the valve body so

that positioning holes are only used once per

rotational position of a flow ring.

GENERAL MAINTENANCE

Emerson recommends that all Clarkson ZP300

series valves be inspected every 60 days.

The following points should be examined and

corrected as required:

WARNING

If valve is not in line the gate must be open or

partially open to avoid damage to valve and flow

ring.

1. Cylinder rods, rod boots: look for excessive

corrosion, bitumen build-up, tears in rod

boot, etc. Check rod boot connections.

Check for cylinder rod seal blow-by.

2. Packing gland: check for leaks or worn

packing. If leakage is occurring around the

packing gland, tighten the packing gland

bolts evenly at all points, being careful not to

overstress the bolting. (On some valves this

will require two wrenches, one to tighten

the nut and the other to hold the packing

bolt from turning.) If the valve requires

repacking, see additional instructions for

repacking on page 6.

3. Flow rings: the valve must be out of line

to properly examine flow rings. Look for

erosion of hard surfacing and base metal.

If base metal is exposed under the hard

surfacing, ring should be replaced. If no

erosion of base metal, ring may be rotated

so worn area is moved from wear path to

gain additional service life.

4. Resilient seats: examine seat for cracks,

cuts, corrosion, erosion or swelling.

Evidence of any above defects may justify

replacement if seat has recorded evidence

of leaking when closed, or condition is

assessed by maintenance engineer to be

at risk of pending failure. To replace a seat

disassembly of valve is required.

5. If possible stroke the valve through the full

open and closed position to make sure it is

functioning properly.

INSTALLATION AND MAINTENANCE INSTRUCTIONS

NOTES

1. Stop all small leaks as soon as possible as

considerable damage can be done to the valve

and the surrounding area if leakage is allowed to

continue.

2. Replacement parts including replacement liners,

hand wheel and yoke assemblies, gates, packing

glands, and packing can be provided from our

factory. If valve requires further repair, please

contact our office for an estimate of feasibility and

cost of repair.

REPACKING INSTRUCTIONS

1. Each packing piece is cut a bit longer to add

some compression within each layer and to

accommodate for fraying strands of packing

at each end. The size, length, and quantity

of each piece can be found in the relevant

Table. Each layer shall alternate between

both the packing width pieces and the

position of the smaller end pieces, as shown

in Figure 12. Smaller end pieces will always

be the piece to deform into remaining cavity.

Note: ensure body O-ring remains

protruding from packing box after

installation of packing.

2. Method of installing packing is shown in

Figure 13. Place one end of packing to side

of packing box. The other end should touch

other packing pieces once installation of

packing commences.

3. Start at the hump of each packing piece

and pack the packing with a packing tool,

as shown in Figure 14. Once the pieces are

together to form the first layer, prepacking

with a packing tool is required to fill in any

gaps that can or cannot be seen. Each layer

will require prepacking.

Note: do not let packing pieces to twist

during installation.

4. Alternate packing layers, as shown in

Figures 12 and 15.

5. If packed properly, the smaller pieces

should fill in the cavity. Each layer of end

pieces should be stacked in a specific way

so that a piece of packing is sitting on top

of a split line from the previous layer, as

shown in Figure 16.To get the smaller

pieces to fill in the cavity, opposite sides

will have to be compressed to obtain an

elongated smaller piece.

Note: not all sizes have smaller end pieces;

some will have equal size end pieces.

6. Install packing gland with studs, Bellville

Washers, and nuts as shown in Figure 17.

For initial tightening of packing gland,

tighten packing gland to achieve a

compression between 0.125-0.375”. Use

Loctite 262 (Red) on studs to secure in body.

Note: ensure each stack is facing the

opposite direction and the final stack is

cupped downward before adding the nut.

7. Tension must be placed on the nut to

prevent the nut from backing out. First

stack starts on the bottom, cupped down on

the packing gland, as shown in Figure 18.

Stacking method is provided on Table 2

CYLINDER OPERATED VALVES

Equipment orientation

The preferred orientation for optimum protection

is with the cylinder in the vertical position. This

position gives the best support to the cylinder

rod and helps reduces the chance of a “flat spot”

developing on the cylinder seals. An acceptable

alternate position for valves with cylinder

diameters of less than 6 inches (150 mm) is with

the cylinder in the horizontal position.

Preparation for storage

Valves may be stored as shipped, provided

the storage facility and equipment orientation

instructions above are followed. If valve

packaging is altered or removed for receiving

inspection, repackage valve as originally

received. Standard packaging materials cannot

be considered sufficient for outdoor storage.

Cylinder storage

These cylinder storage instructions are not

intended to replace the instructions of the

specific cylinder manufacturer and are to be

used as a guide only. If specific instructions

are required, please contact our office. For

storage of up to 3 years; Squirt a high quality

grade of hydraulic oil or synthetic lubricant into

the cylinder ports and operate cylinder 6-12

times on a yearly basis. For storage 3-5 years;

Lubricate as above. Additionally, extend cylinder

rod until the valve is fully closed. Coat cylinder

rod with high quality heavy grease or synthetic

lubricant. Retract cylinder rod until valve is fully

open, drawing lubricant into rod end of cylinder.

Securely plug cylinder ports with pipe plugs, if

cylinder is not prepiped to control accessories.

If cylinder is prepiped to accessories, plug all

input and output ports of accessories.
