Plast-O-Matic TRVDT Relief Valve
Plast-o-matic® type TRVDT three way bypass valves offer high flow relief with 3 port design and are ideal for applications where minimal footprint is required or where use of a piping tee is impractical. The valve has a straight-through flow pattern when closed. When set point is exceeded, the diaphragm is lifted off the center port, and excess flows down and out through the third port at the bottom of the valve.
