STAINLESS STEEL SOLENOID VALVES
TYPE "WR" FULL PORT

- NORMALLY OPEN - 1/2" TO 3" PIPE SIZE
NO DIFFERENTIAL PRESSURE REQUIRED TO OPEN

Specifications:
Max. Fluid Temperature = 400°F
Max. Static Pressure = 200PSI


OPERATION:
Valve closes when energized and opens when de-energized. When the coil is energized the plunger presses the poppet, closing the pilot orifice, and opens a bleed passageway to permit pressure to build above the piston and seat it. Upon de-energizing the coil, the pilot orifice is opened, relieving the pressure above the piston allowing it to leave its seat. The bottom spring allows the valve to operate at zero pressure drop.

APPLICATION:
To control the flow of STEAM. Steam must be free of sediment. Valve operates from zero to maximum differential pressure indicated in table. Valve must be mounted in horizontal pipe with solenoid enclosure vertical and on top.
