The Series TRVDT three-port in-line relief valve is suitable for systems requiring minimal footprint or where the use of a piping tee is not practical. The thermoplastic valve has a heavy-duty design and allows for easy replacement in existing systems. When closed, the valve has a straight-through flow pattern. The pressure setpoint is infinitely adjustable between 50 and 100 psi, and the maximum inlet pressure is 150 psi. Once the set pressure is reached, the diaphragm is lifted off the center port, and the excess liquid flows out through the third port at the bottom of the valve.
