Emerson Cash Valve B Series Service Installation Instruction

CASH VALVE TYPE B 1 ¼" - 2" PRESSURE REGULATOR
OXYGEN SERVICE INSTALLATION INSTRUCTION
Before installation, these instructions must be read carefully and understood.
DESCRIPTION
The Type B pressure reducing and regulating
valve automatically reduces a high inlet
pressure to a lower delivery pressure and
maintains the lower pressure within reasonably
close limits regardless of the pressure
fluctuations on the inlet side of the valve.
SPECIFICATION DATA
Service: Oxygen gas (including medical
grade oxygen)
Sizes: 1 ¼, 1 ½ and 2" (32, 38 and 51 mm)
Connections: Threaded internal inlet and outlet
Body Material: Bronze
Temperature Rating: +150 to -320°F
(65.6 to -195.6°C)
Maximum Initial Pressure: 400 psi (27.58 bar)
Capacity: For specific capacity information,
consult the factory.
GENERAL INSTALLATION INSTRUCTIONS
The Type B regulator should be installed in the
horizontal position with the spring chamber
upright. For other installation requirements,
consult the factory. For easy operation and
maintenance, it is suggested that manual
shut-off valves be installed upstream and
downstream from the valve. Before installing
the valve, all piping should be thoroughly
flushed out to remove any foreign material.
Install the valve with the inlet pipe fitted to
the inlet connection identified on the valve
body. Use a compatible sealant on the male
pipe threads and do not over tighten the
valve connections.

CONSTRUCTION
Bronze body, brass internal trim, Buna-N
diaphragms and seat, Stainless steel
pressure spring.
All parts are commercially cleaned for
oxygen service.
OPERATING INSTRUCTIONS
Adjusting the Delivery Pressure
The regulator's delivery pressure setting is
adjusted by turning the Adjusting Screw (2) or
optional T-Handle (1) at the top of the Spring
Chamber (5) after loosening the Adjusting
Screw Lock Nut (3). 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.
MAINTENANCE INSTRUCTIONS
CAUTION
Before attempting to replace any spare parts, be
sure to shut off all pressure connections to the
valve. With the valve closed, the 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.
Refer to section view for parts identification.
Repair parts can easily be installed without
removing the regulator from the line.
