Installation & Maintenance Instructions
3-Way PTFE Diaphragm
Series TRVDT is a 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 center port, and excess flows down and out through the third port at the bottom of the valve. 1/2″ – 1″ sizes in most popular thermoplastic materials and connections; 5 – 125 PSI set range. NOTE: Series TRVDT is a Specialty Custom product; please contact factory for price and availability. Minimums may apply.

Inline Rolling Diaphragm 2-Way
Series RVDM features a primary rolling diaphragm and a secondary flat diaphragm which incorporates the Plast-O-Matic patented Fail-Dry design for added protection. The rolling diaphragm provides greater sensitivity than non-diaphragm style relief valves, and is ideal for all applications without vacuum on the outlet. 1/2″ – 1″ sizes in most popular thermoplastic materials and connections; 5 – 100 PSI set range (5 – 125 PSI on 1/2″ only).
