Xylem-Bell & Gossett 132204 1-1/2" NPT Male Triple Duty Valve

The Bell & Gossett Model 3DV-1-1/2NMF Triple Duty Valve combines three essential valves into one compact unit: a calibrated balance valve, a spring-loaded check valve, and an isolation/shut-off valve, providing all the functions normally required on the discharge side of pumps in HVAC hydronic systems. This innovative design saves valuable installation space and reduces both initial costs and installation time.

Key Features:

• Brass body construction with chrome-plated brass ball and glass-filled Noryl check valve with stainless steel spring
• 1-1/2" NPTM x NPTF connection for reliable threaded installation
• Cv rating of 25 for excellent flow capacity
• Temperature range of -4°F to 250°F
• Suitable for pressures up to 200 PSI
• Two extended pressure/temperature test valves for ease of installation in insulated systems
• Memory stop feature allows return to set point after shut-off
• Calibrated nameplate for accurate system balancing and flow throttling

The 3DV series utilizes a calibrated ball valve design that provides precise flow control and complete shut-off capability. The integrated spring-loaded check valve prevents backflow and gravity circulation, while the calibrated balance valve allows for accurate system balancing. This three-in-one solution is ideal for commercial HVAC applications, eliminating the need for separate components on pump discharge lines.
