Taco's "Plus Two" Multi-Purpose Valve is five valves in one, combining all the valve functions that are normally required on the discharge side of a centrifugal pump in a hydronic heating or cooling system in a single body.
The "Plus Two" is a Shut-Off Valve, a Non-Slam Check Valve, a Balancing Valve and a Flow Metering Valve, in one versatile package. In addition, you can easily convert the valve from a straight pattern to a 90-degree, right-angle pattern in the field
The "Plus Two" Valve offers performance-- low pressure drops that are equal to or better than any valve on the market today--and convenience: You can replace the stem seal packing under full system pressure.
The "Plus Two" Multi-Purpose Valve is made of ductile iron with stainless steel and bronze fitted construction to provide years of trouble-free service. It is available in sizes ranging from 1 1/2" through 12", with flanged or grooved end connections (1 1/2", 2" and 2 1/2" units are threaded connections).
