106 / 206-RPS-D Pressure Differential Sustaining Valve

The 106-RPS-D and 206-RPS-D pressure differential sustaining valves are based on the 106-PG or 06-PG main valve.

The RPS-D uses the 81-RPD pilot valve and has two sensing connections. The valve and pilot remain closed until the difference between the two pressures exceeds the pilot setting. Under flowing conditions, the pilot reacts to small changes in pressure to control the valve position by modulating the pressure above the diaphragm. The pilot setting establishes a differential pressure that is held relatively steady despite changes in system pressure or flow.

Maintains a minimum differential pressure
Easily adjustable differential pressure setting
Valve closes drip-tight when the pressure differential is less than the pilot setting

106 / 206-RPS-RR Surge Anticipating on Rate of Rise of Pressure Relief Valve

The 106-RPS-RR and 206-RPS-RR surge anticipating relief on rate of rise valves are based on the 106-PG or 206-PG main valve.

The valve is installed downstream of the pump check valve(s) and has two pilots, the 81-RP and the 81-RPD. Both pilots sense pressure through a connection to the header pipe. The 81-RP high pressure pilot acts as a standard relief pilot, opening on excessive pressure. The 81-RPD differential pilot responds to the pressure differential across its diaphragm. A pressure differential is created when there is a system pressure increase. The flow into the accumulator creates a pressure drop across the fixed restriction, which lowers the pressure in the connection between the fixed restriction and the pilot.

The pilot senses the pressure difference between this lower pressure and the header pressure. This difference occurs at the initiation of the pressure surge, providing the time necessary for the valve to open in anticipation of the high pressure.

Protects against power failure surges or pressure waves caused by velocity changes
Unaffected by header pressure and over sizing
Quick opening relief
Easily adjustable pressure setting
No electrical services required

A106-DL Dynamic Lifter Spring Pressure Relief Valve

The A106-Dynamic Lifter (DL) sewage pressure relief valve is a direct acting spring loaded relief valve.

The valve is adjusted to open when the pressure exceeds the set-point, which is approximately 10% above the normal operating pressure. The valve closes drip-tight when pressure falls below the set-point. The DL is connected on a tee off the main line and usually discharges relief flow back to the main sump to reduce the surge over-pressure. A speed control permits adjustment of the closing speed.

The opening force is boosted by the line pressure operating, via the separation chamber, on the piston. By applying external pressure to the test connection, the valve may be cycled open for routine maintenance.

Ideal for:

raw water that contains organics
lower pressure sewage lift stations
booster sewage stations
Low maintenance
Hygienic and minimal time to flush and test operations
Premium materials reduce maintenance, providing the lowest long-term cost of ownership

106 / 206-DW Deep Well Pump Control Valve – Double Chamber

The 106-DW and 206-DW deep well pump control valves are installed in a tee between the pump discharge and the check valve.

The valve is normally open, and, on pump start-up, a pilot solenoid is energized to start closing the valve at a rate governed by the closing speed control.

Initially, the valve discharges air, water and sand to waste. The open valve discharges all pump flow. As the valve closes slowly, flow is transferred to the main line smoothly, increasing the pipeline flow without surges. When the valve is fully closed, all pump flow is in the pipeline, with no control valve losses.

When shut-down is required, the pilot solenoid on the valve is de-energized to commence opening. The pump is kept running while the valve slowly opens. Increasing proportion of the flow is diverted to waste with less passing through the check valve, until all flow is diverted through the nearly fully open DW valve. The pipeline check valve closes quietly without surges. When the DW valve is almost fully open, a stem mounted cam triggers the limit switch to stop the pump.

Prevents pump starting and stopping surges
No energy loss while pump is running
Separate opening and closing speed controls
Discharges initial air/water silt to waste, on well applications.
Discharges stagnant water at start-up from dormant wells

106 / 206-EF-8837BX Excess Flow (Burst Control) Valve

TThe 106-EF-8837BX and 206-EF-8837BX excess flow valves are based on the 106-PT and 206-PT Double Chamber main valves. The valve is designed to shut-off tightly when flow exceeds a predetermined amount.

The 625-RPD pilot senses the pressure drop of the valve and closes the valve when the tripping flow is reached. Typical pressure drop at tripping is 5 psi / 0.35 bar.

Tripping flow is adjusted by limiting the valve opening with the X102 Stroke Limiter. 10 psi / 0.7 bar inlet pressure must be maintained at the valve inlet when the valve has tripped to prevent self re-setting. This valve closes fast and from a significant velocity. If the upstream pipe is longer than 2,000 ft /600 m, closing speed control should be included. When tripped (closed), this valve has a continuous exhaust of about 1 GPM / 0.063 L/sec to drain.

Tight shut-off when flow exceeds a pre-determined amount
Manual re-activation required after failure
“Failure Signal” options available

106 / 206-RF Flow Limiting Control Valve

The 106-RF and 206-RF Flow Limiting Control Valve are based on the 106-PG or 206-PG main valves.

The valve is ideal for limiting the flow to a pre-determined maximum (via maintaining a continuous pressure differential across an orifice). When the pressure differential is less than the set-point, the valve opens, allowing flow to meet predetermined demand. At the desired maximum set-point, the pilot reacts to small changes in sensing pressure and controls the main valve position by modulating the pressure above the diaphragm.

When the pressure drop across the orifice exceeds the set-point, the valve closes slightly, limiting the flow to the pre-set maximum. The orifice is usually sized to generate a pressure differential of 3 to 5 psi / 0.2 to 0.35 bar at the desired flow. Adjusting the pilot setting permits the maximum flow to be changed in the field above or below the original point.

Accurately limits flow to a pre-set maximum
Easily adjustable flow limit

106 / 206-PR-SM Pressure Reducing Control Valve with Integral

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.

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
