Stainless Steel Full Port, Single Chamber, Hydraulically Operated Valve
The 106-PG series control valve is designed to suit a large variety of applications such as pressure, flow or level control. This hydraulically operated valve introduces or releases water from the control chamber above the diaphragm to effectively maintain accurate water control.
Single Point Insertion Flow Metering Valve
The Singer Model 106-SPI-MV is a Single Point Insertion Electromagnetic Flow Meter, installed and calibrated in conjunction with a Singer Valve to provide an accurate flow rate that can be utilized with the metering valve as a stand alone option or built into a 106-2SC-PCO pilot system to provide complete flow-based valve control.
The sensor is available for one-inch taps, depending upon valve size and application. The compact insertion design fits in confined spaces and offers complete accessibility. The flow meter can be removed for easy inspection, cleaning, calibrating or verification.
This cost effective flow meter option is available for valve sizes from 4” (100mm) to 36” (900mm) inches. The flow sensor comes pre-calibrated from McCrometer’s NIST traceable Calibration Lab and requires no recalibration in the field. With no moving parts and a single-piece design, the SPI Mag’s sensor contains nothing to wear or break, and it is generally immune to clogging by sand, grit or other debris.
The 106-SPI-MV Mag is profiled for the valve body, further enhancing its measurement accuracy by allowing precise determination of mean velocities.
Single Process Controller
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.
Hydraulic Check Valve
The 106-HC and 206-HC hydraulic check valves are based on the 106-PG or 206-PG main valve. The valve functions as a two position valve - either fully open or fully closed.
The HC allows one way flow only. Under normal forward flow, the valve opens as the higher inlet pressure lifts the inner valve assembly and the fluid in the upper chamber is discharged to the lower pressure, downstream side of the valve.
When pressure is reversed, the now higher downstream pressure is applied to the upper operating chamber as flow reversal occurs. The diaphragm / inner valve assembly moves down and the valve closes tightly.
Pump Control Panel
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.
Pressure Reducing Pilot
The model 82-PR is a spring and diaphragm operated, normally open pilot valve, with the sensing chamber(s) separated from the operating chambers. It closes when the control pressure below the diaphragm exceeds the force of the spring. The model 82-PR is used as the standard low pressure pilot on model RPS-L&H anticipating surge valves.
The model 625-RPD is a remote sensing, spring and diaphragm operated, normally closed pilot with large diaphragm area for increased sensitivity. The pilot opens when the control pressure exceeds the spring force or the differential established by the spring. The model 625 is used for special applications where a low pressure set point or highly sensitive and responsive pilot is required.
Differential Relief Pilot
The model 106-RD is a spring and diaphragm operated, normally closed pilot designed to allow flow when the inlet pressure exceeds the outlet pressure by a predetermined amount. The model 106-RD is used as a differential control valve on Singer model 106-A-Type 4 altitude control valves.
Rotary Float Pilot (On / Off)
The 43 stainless steel float actuated pilot with non-modulating rotary motion, provides non-modulating On-Off operation of the main valve. It has higher capacity and faster response time than other non-modulating float pilots. The differential between the level where the main valve opens and the level where the main valve closes, is adjustable. The 43 pilot allows for faster operation of the main valve over traditional float pilots, due to increased port size. The standard configuration is for the pilot to close the main valve on high level and open the main valve on low level. The 43 pilot is used on all non-modulating model F-Type 5, 106 and 206 series float valves.
The 43 pilot has a higher pressure rating 150 psi / 10.35 bar as compared to Model 39 (80 psi / 5.5 bar).
The pilot shall be a Singer Model 43.
Non-Modulating Float Pilot with Vertical Rod
The 39 non-modulating float pilot is designed to operate an On-Off float valve. The differential between the level where the valve opens and the level where the valve closes, is adjustable. The standard configuration is for the pilot valve to close on high level and open at a low level.
The 39 pilot is used as the standard pilot on all non-modulating F-Type 5, 106 and 206 series float valves.
