- Maximum inlet pressure: 1600 kPa [230 P.S.I.] (LV25 up to 2000 kPa).
- Maximum temperature: 65°C.
- Pressure compensated to give constant outlet pressure regardless of inlet pressure.
- Adjustable outlet pressure: 200 - 600 kPa [29 - 87 P.S.I.].
- Removable cartridge for easy servicing.
- Integral 60 mesh (250 micron) filter.
- DR (Dezincification Resistant) brass.
Flow Chart
Installation
- Refer to Technical Area
for installation guide.
- Do NOT install Limiting Valve in the ground.
- Do NOT apply heat near valve during installation.
- Install so that both hot and cold supplies are balanced.
- Can be installed in any orientation. For external application, cartridge must be at
bottom.
- Must be installed with correct Expansion Valve fitted down stream of a limiting valve.
- To adjust outlet pressure use large Philips/Pozi screw driver, turn adjusting screw
clockwise to increase (1 turn = 60 kPa [9 P.S.I.]).
Removable Cartridge
- All valve seats are contained within cartridge.
- No need to remove body from valve train.
- Unscrew cartridge to replace or clean filter.
- Removal of cartridge will not affect set pressure.
