Modulating Float Pilot
Model 35 is a Stainless Steel modulating float pilot with a Stainless Steel fl oat, suitable for remote installation on a tank or reservoir. It positions the main valve in proportion to the Reservoir level. Standard configuration is for the pilot to close on rising level.
Specify Reverse Acting for the pilot to open on rising level.
The Stainless Steel float connects to the pilot using a 10 in / 250 mm Stainless Steel rod.
Modulating Float Pilot with Vertical Rod
The 34 modulating float pilot is comprised of a copper float and brass rod assembly which moves vertically. As the level rises, the float lifts and the valve closes. The 34 pilot is optional pilot, available for modulating applications where the float and rod are installed in a still well and / or vertical action is preferred.
Modulating Float Pilot
The R-400 is a modulating float pilot with a plastic float, suitable for remote installation on a tank or reservoir. It positions the main valve in proportion to the reservoir level. Standard configuration is for the pilot to close on rising level. Specify “Reverse Acting” for the pilot to open on rising level. The polypropylene float connects to the pilot on a 10 in / 250 mm brass rod.
The R-400 pilot is used as the standard float pilot on all 106 and 206 series modulating float valves.
Differential Pressure Relief Pilot
The 81-RPD is a remote sensing, high capacity, spring and diaphragm operated, normally closed, differential pilot. The inner valve is held closed by the spring. When the pressure under the diaphragm overcomes the combined forces of the spring setting and the pressure above the diaphragm, the pilot opens. The 81-RPD valve is used for remote sensing of a differential pressure for normally closed applications.
High Pressure Relief Pilot
The 83-RP is a spring and diaphragm operated, normally closed pilot specifically designed for high pressure applications. The inner valve is held closed by the spring. When the control sensed pressure below the diaphragm exceeds the force of the spring, the pilot valve opens.
Model 83-RP pilot is used as the standard pressure relief pilot where the operating pressures are excessive, such as a 300 psi / 20.7 bar level.
Pressure Relief Pilot
The 81-RP is a remote sensing, high capacity, spring and diaphragm operated, normally closed pilot. The inner valve is held closed by the spring. When the sensed pressure increases above the spring setting, the pilot opens. Model 81-RP pilot is used as the standard pressure relief/sustaining pilot on all 106 and 206 series valves.
Rate of Flow Pilot
The 160-RF pilot is a spring and diaphragm operated pilot designed to sense a differential across an external orifice plate. It is a normally open pilot that also has a sensing port is in the spring casing, above the diaphragm and is available in stainless steel. The inner valve is held open by the spring and when the control pressure below the diaphragm exceeds the combined forces of the spring and the sensing pressure, the pilot valve closes. The 160-RF is the standard rate of flow control pilot on all 106 and 206 series valves.
Internal Drop Check
The Internal Drop Check (IDC) ensures quick positive shut-off whenever normal forward flow stops, this action will prevent reverse flow while reducing surge events.
The IDC assembly is a spring assisted, silent, mechanical check option for standard Singer main valves and comes in sizes ranging from 2 in / 50 mm – 36 in / 900 mm.
The IDC is a standard feature on the 106-PTC and 206-PTC series control valves and is available as on optional add-on for control valves larger than 2 in / 50 mm.
Select Singer main valve specifications from the main valve section and incorporate the following addendum:
No Yellow Metals
Yellow metal components such as Brass, Bronze and Copper may not be acceptable materials in harsh water conditions or in specific specifications for a variety of reasons. All or any portion of yellow metals in the internals of main valves may be upgraded to stainless steel. All or any portion of yellow metals on pilots or pilot tubing and fittings may also be upgraded to stainless steel.
Limit Switch Indicator
The X129 limit switch is actuated by the opening and closing of a main valve. The assembly is fully adjustable over the entire valve stroke. Layout variations allow up to four separate switches to be mounted and actuated off the same stem.
