Watts 9751-19 Valve
The Watts 9751-19 Valve, specifically the PV20-C series pilot, is an essential component for technicians managing automatic control valves in hydronic and water distribution systems. This 1/2" direct acting pilot valve is engineered to maintain precise system pressure, operating efficiently within a 20-200 PSI adjustment range. Constructed with a heavy-duty brass body and high-grade Buna-N elastomers, this pilot ensures a positive seal and long-term reliability in high-cycle environments. The large diaphragm-to-seat ratio allows for exceptional sensitivity, enabling the valve to modulate between open and closed positions within very tight pressure tolerances. Designed for remote sensed or self-contained pressure relief, sustaining, or backpressure applications, the Watts PV20-C provides the responsive control necessary to protect downstream piping and fixtures from transient pressure spikes. For field adjustments, the top-mounted adjustment screw allows for streamlined calibration to meet specific site requirements without removing the valve from the line.
Key Benefits- Broad Pressure Versatility: The 20-200 PSI spring range accommodates a wide array of commercial and industrial setpoints.
- Enhanced Sealing: Features Buna-N seat material for superior chemical resistance and tight shut-off performance.
- Precision Control: High sensitivity diaphragm ensures the main valve responds accurately to minute changes in upstream pressure.
- Serviceable Design: Compact 1/2" NPT footprint allows for easy in-line maintenance and pilot replacement.
What is the maximum inlet pressure for the PV20-C?
Standard models are rated for a maximum inlet pressure of 450 PSI, though the control range is limited by the installed spring (20-200 PSI for this unit).
Can this pilot be used for lead-free applications?
While technical specs vary by production date, the Watts 9751-19 is often utilized in surge control and non-potable pilot lines; check the LFPV20C variant if lead-free certification is strictly required for certain potable water codes.
Does this valve come with a sensing port?
Yes, this unit typically includes a 1/4" NPT side sensing port to facilitate remote sensing of upstream or downstream pressure based on your control logic.
