Keystone K-Lok Series H IOM Owner's manual

Brand: Keystone

Model: K-Lok Series H IOM

Type: Owner's manual

Keystone K-Lok Series H IOM is a high-performance butterfly valve designed for demanding industrial applications. It features a compact and lightweight design, making it easy to install and maintain. The valve is available in a variety of materials and configurations to suit different process requirements. With its superior sealing capabilities and low operating torque, the Keystone K-Lok Series H IOM is an ideal choice for applications requiring reliable and efficient flow control.

IMPORTANT

Whenever possible, install the valve with the shaft

in the horizontal position and, if possible, with the

cast-in disc stop located top-side of the pipe. If the

shaft cannot be positioned horizontally, position

the shaft so that it is not on the vertical centerline

in a horizontal pipe run. This will minimize any

depositing of solid particles present in the fluid

into the lower bearing.

CAUTION

The valve should be installed in the closed

position to ensure that the seat and disc are

not damaged during installation. Particular

care should be taken with valves equipped with

‘failopen’ actuators. Failure to ensure proper

handling may result in damage to the valve.

If the pipe is lined, confirm that the disc rotation

does not contact the lining during the opening

stroke. Failure to confirm that the disc rotation

does not contact the lining may result in damage

to the valve.

INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS

INSPECTION

1. Carefully remove the valve from the

shipping package (box or pallet) to avoid

any damage to the valve and, in the

case of automated valves, to the electric

or pneumatic/hydraulic actuator or

instrumentation.

GENERAL

Suggested installation orientation is with

valve shaft horizontal or inclined from vertical.

Unless otherwise recommended by Emerson,

mount the valve in the preferred direction with

the directional arrow pointing to the lower

pressure side so that the front face of the disc

will be upstream when the valve is in the closed

position.

Thermal insulation of the body is mandatory for

operating temperatures above 200°C (392°F).

H-series K-LOK offers the following body

styles:

Series H1W and H2W - Wafer

Series H1L and H2L - Lugged

Before installation these instructions must be read fully and understood

2. Prior to installation, clean the inside of

the valve. Ensure that there are no solid

objects such as pieces of wood, plastic or

packing materials within the valve or on

thevalveseat.

3 Inspect the seat and disc edge to ensure

that they were not damaged in handling.

This is especially important in the case of

valves with ‘fail-open’ actuators.

4. Confirm that the materials of construction

listed on the valve nameplate are

appropriate for the service intended and

are as specified.

5. Locate the directional arrow on the body

that defines the preferred mounting

orientation in respect to the pressure. In

most cases, the valve is properly installed

when the actual fluid flow or high pressure

is acting on the front face of the disc when

the valve is closed.

6. Ensure that the packing gland bolting nuts

are tight.

Removing the disc-to-shaft wedged pin

connections

1. Open the disc to its full open position.

Note: on valve sizes DN 250 (NPS 10) and

larger, it is recommended that two workers

perform the wedged pin (5) removal process.

2. Place the disc in a vice, see Figure 1.

3. Locate a steel punch on the wedged pins

and strike the punch with ahammer.

Note: some of the weld on the three wedged

pins may need to be removed by grinding.

DISASSEMBLY

To begin disassembly, refer to the parts list

(Figure 2) and proceed as follows:

WARNING

Depressurize the valve and associated piping

before disassembly. Failure to do so may cause

serious personal injury and/or equipment

damage.

1. Remove the valve from the line. Clean

the valve according to proper cleaning

procedures as outlined by the plant or

according to a prescribed procedure.

2. Remove the actuator and relevant

connecting key. Note the actuator position

relative to the valve.

CAUTION

Throughout disassembly and assembly, always

use cardboard or brass shims to protect the

valve body, disc, flange and sealing surfaces from

damage. Failure to do so may result in serious

damage to the valve.

OPERATION

The H-Series K-LOK has been designed to

require a minimum of maintenance. Generally,

only maintenance on the packing box is

required.

MAINTENANCE

If shaft leakage is observed through the packing

box, tighten the gland nuts.

Note: do not over-tighten packing box gland

nuts. Over-tightening will increase the torque

required to operate the valve. When tightening

the gland nuts, use half-turn increments until

leakage has stopped.

VALVE CHECKOUT

1. Tighten the packing gland bolting just

enough to prevent shaft leakage. Over-

tightening will decrease packing life and

increase operating torque requirements.

2. Check the operation of the valve by stroking

it to ‘full open’ and ‘full close’. To determine

the valve orientation of the disc, double

D’s and keyways are aligned with the disc.

The valve disc travels clockwise to close.

3. For automated valves, set the air pressure/

electrical voltage for at least the minimum

given to operate the actuator. For pneumatic

actuators, do not apply more than 1.25times

the pressure for which the actuator was

designed.

INSTALLATION

The valves are shipped with flange gasket

surface protection. Before installing the valve,

remove the protection and carefully clean and

de-grease both surfaces with a solvent.

Series H1L and H2L - Lug style

1. Orient the valve with the directional flow

arrow (preferred direction) pointing in the

proper direction.

2. Insert the valve between the flanges until

the two bottom holes in the valve align with

the two lower flange holes.

3. Insert a bolt or stud through the flange and

thread it into the holes in the valve body.

This will allow the valve to center itself

properly for the installation of the flange

gaskets.

4. Install the flange gaskets and the remaining

flange bolting.

5. Use the crossover method to tighten all

flange bolting.

Series H1W and H2W - Wafer style

1. Orient the valve with the directional flow

arrow (preferred direction) pointing in the

proper direction.

2. Insert the valve between the flanges until

the alignment holes at either side of the

valve match the corresponding holes in

the flanges.

3. Insert a long bolt or stud through the flange

and thread it through the alignment hole.

This will allow the valve to center itself

properly for the installation of the flange

gaskets.

4. Install the flange gaskets and the remaining

flange bolting.

5. Remove the long bolts/studs from the lower

alignment holes and replace with correctly-

sized bolts.

6. Using the crossover method, tighten all

flange bolts.
