Model 106-A-Type 4
The M106-A- Type 4 altitude control valves are based on the M106-PG main valve, and is ideal for maintaining a preset maximum water level. The valve functions as a two position control valve, either fully open or fully closed.
The Type 4 allows normal forward flow to fill the storage tank to the maximum level, then closes drip-tight at the set-point. It opens to refill the tank once the level drops an adjustable amount below the high water level. Note: Distribution from the storage tank is through a separate pipeline. This valve does not operate as a check valve to prevent reverse flow.
Singer Model 106 EPDV-A-10506A Pneumatic/Electric Solenoid control valve is based on the Singer Model 106 PG-UL Deluge main valve.
The solenoid pilot provides on-off position operation. The solenoid, using an independent air supply, either admits inlet pressure into the main valve operating chamber from the inlet of the main valve via a high capacity relay valve or releases pressure from the relay valve and therfore the main valve operating chamber. This either opens or closes the main valve. The pilot system is usually piped to discharge to drain (atmosphere).
The 106 EPDV-A-10506A is available with the main valve closed when the solenoid is de-energized (NCnormally closed. This refers to the main valve, not the solenoid).
Singer Model 106 PDV-A-10508A Pneumatically Operated Control valve is based on the Singer Model 106 PG-UL Deluge main valve.
The high capacity relay valve provides on-off position operation. The high capacity relay valve, using an independent air supply, either admits inlet pressure into the main valve operating chamber from the inlet of the main valve or releases pressure from the operating chamber. The pilot system is usually piped to discharge to drain (atmosphere).
Models 106-PR-10159 UL / 106-PR-8702A ULC
The 106-PR, which is UL and ULC labelled and listed, is ideal for automatically reducing a higher inlet pressure to a steady lower discharge pressure, regardless of fluctuations in flow or inlet pressure.
The valves are based on the 106-PG or A106PG control valves and are available in a complete range of sizes from 2 in / 50 mm to 8 in / 200 mm (sizes depend on UL classification). In typical pressure reducing applications, the globe style 106-PR is often the preferred valve style.
The 106-RPS-8700A pressure relief valve, which is UL / FM labelled and listed, automatically relieves excess pressure in the fire protection system to discharge. The RPS series valves will also automatically modulate to relieve excess pump capacity during pump start up and shut down, allowing the pump to operate without causing surges.
These relief valves are based on the 106-PG or A106-PG main valves and come in complete range of sizes from 2 1/2 in / 65 mm to 8 in / 200 mm. In typical pressure relief application, the angle style A106-RPS-8700A is often the preferred selection.
