RF - Rate of Flow

:: The RF pilot valve (model 160-RF) senses the pressure differential across the specially sized orifice plate. 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 (.2 to .35 bar) at the desired maximum flow. Adjusting the pilot setting permits the maximum flow to be changed in the field above or below the original point.

Note: Valve Image is shown with optional orifice housing

SC - Solenoid Control

:: The Singer Valve solenoid control valve provides two position (on-off) operation. The solenoid either admits inlet pressure into the main valve operating chamber or releases pressure from the operating chamber. The pilot system is usually piped to discharge at the valve outlet, but can be piped to discharge to drain (atmosphere). The Solenoid Control valve is available either with the main valve closed when the solenoid is de-energized (NC - Normally Closed) or with the main valve open when the solenoid is de-energized (NO- Normally Open). (NC or NO refers to the main valve, not the solenoid.)

EPC - Single Process Controller

:: The SINGER VALVE model EPC is a single process loop controller designed to complement the Singer Model 2SC-PCO Dual Solenoid Control Valve.

Range of application is dependent on the PROCESS VARIABLE (feedback) transmitter used, which includes (but not limited to) common automatic control valve functions with conventional pilots. Model EPC controller reads and compares the process feedback (PROCESS VARIABLE) 4 to 20mA signal to the desired setting (SETPOINT) 4 to 20mA signal. Model EPC then accurately positions the valve to bring the PROCESS VARIABLE towards the SETPOINT until they coincide.

MCP-TP - Electronic Control Panels

:: The SINGER VALVE model MCP Series is a multiple process loop control panel designed to complement the Singer Model 2SC-PCO Dual Solenoid Control Valve. Range of application is dependent on the feedback (PROCESS VARIABLES) transmitters used, which includes (but not limited to) combination automatic control valve functions with conventional pilot.

Model MCP control panel has the ability to monitor multiple processes and remotely control the dual solenoid control valve based on system conditions. The MCP is factory programmed and customized for application needs. The Model MCP control panel can function as a simple single loop controller (i.e. Pressure Reducing, Flow Control, Level Control) to multiple loop controller (i.e. Pressure Reducing and Pressure Sustaining, Flow Control and Level Control, etc.). Singer Model MCP reads transmitted signals and energizes the dual solenoid pilots on the Singer Control Valve. Singer Model MCP can react to any change in conditions by monitoring the system continuously and comparing actual process values to desired setpoint values.

2SC-PCO - Dual Solenoid Control

:: The flow into and out of the upper operating chamber is controlled by the two pilot solenoids. The electronic control determines whether the opening solenoid or the closing solenoid is operated. The change in valve position is dependent upon which solenoid is operated and the duration of the energized period. The electronic control determines the valve function. Virtually any hydraulic function can be achieved using the “open-close” output from the controller to the valve.

25C-MV - Flow Control and Metering

:: The pressure in the upper operating chamber is controlled by operating the pilot solenoids. The PLC within the MV-1 control panel determines whether the opening solenoid or the closing solenoid is operated. The change in valve position is dependent upon which solenoid is operated and the duration of the energized period. The Singer MV-1 control panel computes the flowrate based on valve differential pressure and position and operates the pilot solenoids to match the flow rate to the customer’s pre-determined (adjustable) setpoint. Flow is totalized and displayed via panel readout.

420DC - Electronic Pilot Actuator

:: The Singer Model ( )-420DC or ( )-420AC is a SCADA-based 420-mA motor operated pilot system that provides for a reliable, simple and cost efficient way to automate today's water systems.

In the case of the ( )420-DC, a sturdy slow speed 24VDC motor actuator drive is fitted to a standard Singer Valve pilot, most commonly, the Model 160-Pressure Reducing Pilot (which then becomes Model# 160-420DC.) The minimum system pressure downstream of the pressure reducing valve is set by adjusting the pilot screw that compresses the pilot spring. The motor actuator responds to a 4-20mA signal, rotating the pilot adjusting
screw corresponding to the change in signal. The number of turns is adjustable and may be programmed to suit the pressure change per turn of the pilot screw to produce the desired maximum and minimum downstream pressure. (Note that the system pressure determines the spring selection).
