PLASTOMATIC RELIEF, BY-PASS, BACK PRESSURE & ANTI-SIPHON VALVES
TRVDT Series
Product Description:Series TRVDT high flow relief/by-pass valve with 3-port design, ideal for applications where minimal footprint is required or where use of a piping tee is impractical. Valve has a straight-through flow pattern when closed. When set point is exceeded, the diaphragm is lifted off the centre port, and excess flows "down" and out through the third port at the bottom of the valve.
For applications where a tee can be accommodated, a 2-port valve such as Series RVDT is usually preferred.
