Type: Owner's manual

Cash Valve A-360 and A-361 Pressure Regulators

These pressure regulators are designed to automatically reduce a high inlet pressure to a lower delivery pressure and maintain that lower pressure within reasonably close limits, even during high flow rates. They can be used with air, water, oil, gases (except steam) and other non-corrosive liquids. The regulators are available in 1/4", 3/8" and 1/2" sizes and have a maximum inlet pressure of 400 psi. The outlet pressure range is 0-250 psi.

The regulators are easy to install and can be mounted in any position. They come with a pressure gauge for easy monitoring of the outlet pressure. The delivery pressure can be adjusted by turning the adjusting screw at the top of the spring chamber.

CASH VALVE A-360 AND A-361 PRESSURE REGULATORS

INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS

DESCRIPTION

Types A-360 and A-361 pressure reducing and

regulating valves automatically reduce a high

inlet pressure to a lower delivery pressure and

maintain that lower pressure within reasonably

close limits, even during high flow rates.

Type A-360 is 2-way; Type A-361 is 4-way with

gauge taps on sides of body.

Inlet Pressure: 400 psi (27.57 bar)

Outlet Pressure

Range: 0-250 psi (0-17.23 bar)

INSTALLATION INSTRUCTIONS

Types A-360 and A-361 regulators can

be installed in any position. For ease of

maintenance and repair however, it is

suggested that the valve be installed in a

horizontal line with the spring chamber upright.

For convenient operation and maintenance,

manual shut-off valves should be installed

upstream and downstream from the valve.

Before installing the valve, the piping should be

thoroughly flushed out to remove any foreign

material. Install the valve with the inlet pipe in

proper relationship to the flow arrow stamped

on the valve body.

OPERATING INSTRUCTIONS

Adjusting the Delivery Pressure

The regulator's delivery pressure setting is

adjusted by turning the adjusting screw (1) at

the top of the spring chamber after loosening

the adjusting screw lock nut (2). To increase

the delivery pressure, turn the adjusting

screw clockwise (into the spring chamber).

To decrease the delivery pressure, turn the

adjusting screw counter-clockwise (out of the

spring chamber). Tighten the adjusting screw

lock nut after the adjustment has been made.

NOTE:

When adjusting the delivery pressure, draw

flow and shutoff downstream to check

pressure set.

INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS

MAINTENANCE INSTRUCTIONS

The following procedures are provided for

servicing the recommended spare parts for the

Types A-360 and A-361 regulators. Repair parts

can easily be installed without removing the

regulator from the line.

CAUTION

Before attempting to replace any spare parts be

sure to shut off all pressure connections to the

valve. With the valve closed, however, system

pressure could still be locked between the shut

off valve and the inlet and/or outlet sides of the

regulator. Before proceeding with any valve

service be certain to relieve the pressure from

BOTH sides of the regulator.

Servicing Diaphragm(s), Top O-Ring, and

Pressure Spring

1. Loosen the lock nut and turn the adjusting

screw counterclockwise until the pressure

spring is no longer under tension. When

reassembling, run the adjusting screw down

until the lock nut almost touches the spring

chamber. This will give you approximately

the same set as before disassembly.

2. Remove the spring chamber from the

body. When reassembling, torque to

50-60 ft-lbs (67.8-81.3 N•m).

3. Remove the spring button, pressure

spring, diaphragm stop, and diaphragm

subassembly. When reassembling,

torque diaphragm nut to approximately

75 in-lbs (8.48 N•m).

4. If the top o-ring is to be serviced, remove

the two retainer plate screws and remove

the retainer plate and top o-ring. Lubricate

top o-ring with Dow Corning Molykote 111 or

equivalent before installing.

5. Inspect all parts for wear and damage and

replace if necessary. Reassemble parts

in reverse order. DO NOT OVERTIGHTEN.

Follow the Operation Instructions to reset

the delivery pressure.
