WATER WORKS

301-4

Altitude Pilot Valve

An altitude pilot valve that is spring and diaphragm operated; it controls the water level in a reservoir by sensing the hydrostatic head. When the hydrostatic head equals the spring force, the pilot connects port “X” (connection to main valve inlet ) to port “K” (connection to main valve bonnet). The main valve closes. When the hydrostatic pressure decreases slightly, the port “X to K” connection is closed by the inner valve. When the hydrostatic pressure is reduced even further, the pilot connects port “K” (main valve bonnet) to “EX” (exhaust to atmosphere). Then the main valve opens.

Model 301-4 pilot is used as the standard pilot on all 106 and 206 series altitude valves.

106 / 206-F-Type 5

Non-Modulating Float Valve

  • No overflow, drip-tight close

The 106-F-Type 5 and 206-F-Type 5 non-modulating float valves are based on the 106-PG or 206-PG main valve. It is ideal for allowing normal forward flow to fill water reservoirs to a desired high level and where the pilot and valve of the reservoirs are easily accessible.

The valve functions as a two position valve, either open or closed. The valve remains closed when the reservoir level drops, until the float reaches the pre-determined adjustable minimum reservoir level. The F-Type 5 valve then opens to refill the reservoir and closes tightly when high water level is achieved.

106 / 206-PFC

Pressure Flow Control (Modulation) Valve

  • Reduces pressure when demand is lower resulting in reduced leakage losses and pipe breaks
  • Compensates for pressure loss in a long pipeline to deliver virtually constant pressure at all times at a distant point
  • Simple to set-up and adjust

The 106-PFC / 206 PFC Pressure Modulation Valve is a pressure reducing valve with a special (Patented) pilot that increases downstream pressure as flow increases.

The PFC valve alters and controls pressure with flow to create virtually constant pressure at the critical pressure point in a system. It will also automatically adjust for distribution friction losses. The PFC valve will deliver consistent performance as it has no electrical components and is not affected should the valve chamber be flooded. The valve may be used wherever a standard PRV is installed.

106 / 206-PR-SM

Pressure Reducing Control Valve with Integral Back-up

  • Ideal for applications where failure is not an option
  • Includes a back-up system to protect against diaphragm or pilot failure
  • Reduces unnecessary maintenance
  • Provides downstream surge protection

Product Overview

The 106-PR-SM and 206-PR-SM series control valves are engineered to be used anywhere pressure reducing valve failure is unacceptable. These valves have a second and independent operating system superimposed upon the standard primary system. With the assurance of a back-up system, maintenance schedules may be extended as pressures will continue to be controlled even in the event of failure with the primary system.

Under normal pressure reducing conditions, the primary pilot senses the downstream pressure through a connection at the valve outlet. Under flowing conditions, the pilot reacts to small changes in pressure to control the valve position by modulating the pressure above the diaphragm in the lower operating chamber. The downstream pressure is maintained virtually steady at the pilot set-point that is adjustable.

Should the primary pilot system and / or main valve fail to control the downstream pressure, the independent back-up pilot system will begin to operate. It controls the pressure above the diaphragm in the second operating chamber. The back-up pilot is set slightly higher than the primary pilot. The forces now operating in the top chamber assume control of the inner valve assembly and maintain pressure reducing control. During back-up operation only, there is a small (1 USGPM / 0.063 L/s) continuous discharge that should be taken to drain.

The secondary pilot continually senses the downstream pressure. Should there be a rapid rise in downstream pressure for any reason, the secondary pilot will respond quickly, and will pressurize the top chamber. This will compliment the primary pressure reducing controls and provide faster response.

Specifications

  • The valve shall be a Singer Valve model 106-PR-SM / 206-PR-SM, size “_____”, ANSI Class 150 (ANSI 300, ANSI flanges drilled to ISO PN 10 / 16 / 25 or 40) pressure rating / flange standard, globe (angle), style valve. The Model 160 Pressure Reducing Pilot (Normally Open Pilot) spring range shall be “___ to ___” psi / “___ to ___” bar, with set-point preset at Singer Valve to “___” psi / “___” bar.

  • The primary main valve and pilot system shall maintain relatively accurate control of the downstream pressure regardless of fluctuation in flow or upstream pressure. Should the primary main valve and / or pilot system fail to maintain downstream pressure, the independent back-up pilot system will take over and control the downstream pressure (at a slightly higher pressure).
