Fast-Acting Temperature- and Pressure-Relief Valves for Hot Water



- For Use With: Water
- Specifications Met:
Pipe size of 3/4-2: ASME BPVC.IV
Pipe size of 1/2-2: CSA Certified - Max. Temperature: 210° F
Also known as T & P valves, these open when water temperature reaches 210° F or at the set pressure. They are commonly used with water heaters and storage tanks. All spring fully open at a water temperature of 210° F or the set pressure and remain open until the system is restored below the set point. For remote discharge, valves have a threaded relief port to attach a drain line. Body is bronze for durability and a long service life.
Valves with 3/4 to 2 pipe size meet ASME Code Section IV for hot water.
Valves with an extended body are designed for installation through thick insulation.

Color-Coded Quarter-Turn Shut-Off Valves for Hot and Cold Water
Quickly identify hot and cold water lines with these red or blue valves. The low-profile elbow shape and small handle are made to fit into tight spaces, such as plumbing outlet boxes (sold separately). Connect the NH/NST threads to a water hose on a washing machine or commercial plumbing fixture.
Valves with a solder-connect inlet are used for copper water lines.
Valves with a barbed inlet are compatible with Viega PEX tubing; attach them to your line with a crimping tool and crimping ring (both sold separately).
