PSL limiting valve

PSL limiting valve
CONTROL VALVES
PSL Range - Pressure Limiting Valves
Description
RMC's PSL Pressure Limiting Valves control inlet supply
line pressure to a preset maximum to prevent overpressure situation. The valve remains in the open position
if the pressure in the supply line falls below that preset
maximum pressure.
PSL Pressure Limiting Valves are ideal for installation
with high pressure storage water heaters, water meter
assemblies, water softeners etc. RMC's PSL Pressure
Limiting Valves are of an in-line barrel design.
PSL Pressure Limiting Valves are available in 15 mm and
20 mm configurations.
Features and Benefits
™ Suitable for horizontal or vertical installation
» Valve designed to work effectively in either orientation
™ Available in a range of fixed outlet pressure settings
» 350 kPa, 500 kPa and 600 kPa
™ High pressure and temperature tolerances
» Suitable for a wide variety of pressure limiting
applications
™ Stainless steel seat
» Extended service life
™ Dezincification resistant
» Meets Australian Standard for potable water supply
Application
RMC PSL Pressure Limiting Valves are suitable for use to limit supply pressure to below the set pressure of the expansion
control valve and/or pressure and temperature relief valve on a high pressure storage water heater.
The PSL range valves can be used interchangeably with the PS range.

Product Notes
1.
This valve is of a piston based design and needs a
vent hole to ensure operation. If this valve is exposed
to high inlet pressures (e.g. Poor water conditions
or under water hammer conditions), damage to the
valve can result in water leaking through the vent
hole. This hole should not be covered or filled in
any way to prevent malfunction of this valve. It is
recommended to not install this valve in enclosed
spaces for this reason.
