Type “S” Full Port
To control the flow of Steam. Steam must be free of sediment.
NORMALLY CLOSED – 1/2″ TO 3″ PIPE SIZE
NO DIFFERENTIAL PRESSURE REQUIRED TO OPEN
MAX. FLUID TEMP.
400°F
MAX. STATIC PRESSURE
200 PSI
OPERATION:
Valve opens when energized and closes when de-energized. When the coil is energized the pilot valve opens, relieving the pressure above the piston, which is then lifted from its seat by the plunger. Upon de-energizing the coil, a spring closes the pilot valve and opens a bleed passageway to permit pressure to build above the piston and seat it.
