Watts 0257564 3/4" NPT Pressure Relief Valve 1,438,000 BTU/hr 150 PSI 140X-5-150

The Watts 0257564 140X-5-150  is a 3/4-inch solenoid valve used in HVAC systems to control fluid flow such as water, refrigerant, or air. It works using an electrically driven coil that, when charged, produces a magnetic field. A valve that controls fluid flow is opened or closed by this magnetic field. These valves, which are widely utilized in systems with a 150–200 psi pressure range, are found in air handling units, heating systems, and chilled water systems, among other HVAC equipment. Due to their many advantages such as accurate flow control, quick response times, little maintenance needs, and durability solenoid valves are essential parts of dependable and effective HVAC systems. Because they contain fewer moving parts than other valve types, they require less maintenance.
