Taco Plus Two Multi-Purpose Valve (MPV Series)

  • The Taco Plus Two valve combines essential pump discharge functions in one ductile iron body. Its spring-loaded check mechanism prevents reverse flow, while globe-style throttling and metering ports support system balancing. A calibrated scale and memory indicator allow settings to be recorded and restored. The body can be converted on site from straight to angle pattern.
