Delta Power Company products

“High Pressure” 7 size, 5/8-18 thread, “Mini” series, solenoid operated, 2 way normally closed, pilot operated poppet valve with reverse flow de-energized. OPERATION: When de-energized the HMA-S2A blocks flow from (1) to (2) and allows reverse flow from (2) to (1). When energized, the valve allows flow from (1) to (2) and restricts flow from (2) to (1).

8 size, 3/4-16 thread, “Power” series, solenoid operated, 2 way normally closed, pilot operated poppet valve with reverse flow de-energized. OPERATION: When de-energized the PB-S2A blocks flow from (1) to (2) and allows reverse flow from (2) to (1). When energized the valve allows flow from (1) to (2) and restricts flow from (2) to (1). OPERATION OF MANUAL OVERRIDE OPTION: to override, pull knob out. On the detented version, after pulling knob out twist 180 degrees and release. The valve will remain in that position.

7 size, 5/8-18 thread, “Mini” series, solenoid operated, 3 way 2 position, proportional pressure reducing/relieving valve. OPERATION: When de-energized the EMC-PRV allows flow from (3) to (2) and blocks flow at (1). When energized, the actuator creates a force proportional to the pressure that will be regulated at port (3). Oil is supplied from port (1) to (3) until desired pressure is reached. If pressure at port (3) exceeds desired level, excess oil is vented to port (2) until desired level is reached.  

Special cavity, slip-in style flange retained, direct acting proportional pressure reducing/relieving valve. OPERATION: The EN043-PRR generates a variable pressure in response to a PWM (Pulse Width Modulated) current signal. With no current applied to the proportional solenoid, the inlet port #2 (P) is blocked and the regulated port #3 (U) is vented to port #1 (T). As current is increased, fluid pressure is proportionally controlled at the regulated port #3 (U). On attainment of proportionally determined pressure at #3 (U), the cartridge shifts to block flow at #2 (P), thereby regulating pressure at #3 (U). In this mode, the valve also will relieve #3 (U) to #1 (T) at a variable value over the set reducing pressure.

#8 SAE, inline check valve. OPERATION: The IM-CVA allows flow from (2) to (1), while normally blocking oil flow from (1) to (2). The valve has a guided check ball, which is spring-biased closed until sufficient pressure is applied at (2) to open to (1).
