TYPICAL APPLICATIONS

The 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 20 mA signal to the desired setting (set-point) 4 to 20 mA signal. Model EPC then accurately positions the valve to bring the process variable towards the set-point until they coincide.

2. Van Điều Khiển Từ Xa Solenoid Control Valve 106 / 206-SC  

KEY FEATURES • Positive, drip-tight shut-off • Simple, on-off operation
• Globe or angle style body TYPICAL APPLICATIONS  

  Singer models 106-SC and 206-SC solenoid control valves are based on the Singer model 106-PG or 206-PG main valve.The solenoid pilot valve provides on-off position 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 SC 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.)

3. Van Điều Khiển Từ Xa Dual Solenoid Control for Positioning and SCADA Controls 106 / 206-2SC-PCO

KEY FEATURES • Precise control from remote locations • Process controller compatible • Minimal power needed for stand-by operation • Complete service in-line
• Manual controls for emergencies TYPICAL APPLICATIONS  

  The Singer models 106-2SC-PCO and 206-2SC-PCO dual solenoid electronic valves are based on the Singer model 106-PG or 206-PG main valve.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 SCADA controller to the valve.The Singer Model 2SC-PCO is designed for use with Singer MCP Multi-Process Control Panel or the EPC Single-Process Control Panel.

7. SAP Panel for Model RPS-L&H-ET; Surge Anticipator Panel

  KEY FEATURES

+ Automatically interfaces pressure switch and control valve to protect system from destructive pressure surges

+ Visual indication of operational status

+ Simple to install

+ Minimizes field wiring costs TYPICAL APPLICAITONS  

  The SAP surge anticipator panel provides the interface between a customer supplied, system pressure switch and the Singer surge anticipating control valve. Together they provide protection against destructive pressure surges. The SAP panel energizes the control valve pilot solenoid on an abnormally low pressure reading and/or power failure to pumps. The 12 VDC pilot solenoid is energized to open the main valve and relieve the surge pressure from the system. The RPS-L&H-ET (ET- Electronically Timed) valve is equipped with a hydraulic pilot to relieve on abnormally high pressures. The SAP panel is equipped with adjustable digital delay timers that permit coordination of valve operation with pump start-ups, shutdowns, power failures and down surges. The SAP panel comes equipped with a long life, high capacity 12 VDC battery, industrial grade battery charger with over current and polarity protection, door mounted volt meter and battery test feature. The logical arrangement of indicator lights and the volt meter provide easy supervision of the sequencing and the operating status.

8. Van Điều Khiển Từ Xa Pump Control Panel SPC

    KEY FEATURES

+ Automatically interfaces pump and control valve to avoid starting and stopping surges

+ Visual indication of operational status

+ Simple to install

+ Suitable for use with either in-line booster or deep well by-pass pump control valves

+ Reduces field wiring costs TYPICAL APPLICATIONS  

  The SPC pump control panel provides the interface between the pump motor starter and the Singer pump control valve. The SPC ensures that the pump starts and stops without causing line surges.The SPC panel energizes the control valve pilot solenoid simultaneously with pump start. When pump shut-down is required the panel keeps the pump running while the pilot solenoid is de-energized. The panel turns the pump off just as the control valve completes its full stroke travel. The SPC panel is equipped with delay timers and emergency fault contacts to provide the customer with local and remote indication for various operational failure conditions. The SPC panel is connected to the pilot solenoid and limit switch that are standard components in the control valve pilot system. The panel is also connected to the customer supplied pump discharge pressure switch and the pump motor starter. A second limit switch and emergency shutdown solenoid are optional components for the control valve pilot system. The logical arrangement of indicator lights with the Hand Off Automatic (HOA) selector switch provides easy supervision of the sequencing and the operating status.
