High Pressure 3/2 Solenoid Valve for Power Gas 60 - 160 PSIG
For Spring Return T-Ball Control Valves (See Figure 17 and Figure 18 for Pipeline Schematic).
Two High Pressure 3/2 Solenoid Valves are used in DNGP applications with PSUPPLY from 60 to
160 PSIG. When the solenoid is energized the core is drawn into the solenoid base sub-assembly
opening the valve. When the solenoid is de-energized, the core returns and the valve closes. Each
solenoid is equipped with a valve that operates Normally Closed, in other words, the valve is closed
when solenoid is de-energized; open when energized.

High Pressure 5/2 Solenoid Valve for Power Gas 60 - 160 PSIG
The high pressure 5/3 solenoid is used for DNGP applications where PSUPPLY ≥ 55 PSIG. The 5/3 is
a threaded body, double solenoid, three-position valve with a spring centered, closed center spool. All
ports are blocked when both solenoids are de-energized. Also, looking from the two hole side (below),
the flow pattern is such that when the solenoid on the left is energized, air flow comes from the cylinder
port on the left. This solenoid can be converted from external to internal pilot operation and vice versa
to allow a greater pilot pressure range.
