Description
The Taco Comfort Solutions MPV015-4 is a 1-1/2″ NPT Triple Duty Valve engineered to streamline hydronic system installations by combining three essential functions into a single, compact valve body. Designed for use on the discharge side of hydronic circulating pumps, this valve eliminates the need for separate shutoff, check, and balancing valves — reducing installed cost, saving space, and simplifying system commissioning.
Built to Taco’s exacting quality standards, the MPV015-4 is an ideal solution for commercial and residential hydronic heating and cooling applications where reliability, performance, and ease of installation are paramount.
Key Features
- Three-in-one design: combines shutoff, non-slam check, and calibrated balancing valve functions
- 1-1/2″ NPT end connections for straightforward pipe integration
- Designed for installation on the pump discharge side of hydronic systems
- Calibrated memory-stop handle allows precise flow balancing and easy re-setting after service
- Non-slam check valve function protects the pump from reverse flow damage
- Full shutoff capability for pump isolation during maintenance
- Compact, single-body construction reduces pipe fittings and potential leak points
- Durable construction suitable for commercial and residential hydronic applications
Application
The MPV015-4 Triple Duty Valve is engineered for hydronic heating and cooling systems, including hot water boiler systems, chilled water systems, and closed-loop hydronic circuits. It is installed on the discharge side of the circulating pump to provide complete pump protection and system balancing in one assembly.
Why Choose a Triple Duty Valve?
Traditional hydronic installations require a gate or ball valve for shutoff, a swing check valve for backflow prevention, and a separate balancing valve — each with its own fittings and potential failure points. The Taco MPV015-4 consolidates all three into a single valve, reducing labor time, material costs, and the number of joints in the system.
