Features
  • Response time. Actual test data shows only 175 milliseconds is required to fill a 250 cubic inch volume to 80% of line pressure with a normally closed solenoid operated valve. Where a spring is used to open the valve (normally open valve) only 253 milliseconds is required to fill the same volume.
  • Continuous-duty solenoid. Won’t burn out...even when energized for extended periods. Pilot operated for fast response.
  • Lightweight aluminum spool of extra large diameter assures high-speed performance. Requires only short movement to deliver high-capacity air flow. File-hard anodized surface, polished to an 8 micro-inch finish, withstands wear and abrasion; offers greatest sealing qualities, minimum friction and maximum speed. Spool is balanced so air pressure won’t affect its position.
  • Low-friction, positive sealing ring is actually two seals in one; an outer static seal and an inner dynamic seal bonded to a metallic spacer ring. The ring protects the inner seal from the radical compression absorbed by the other seal. Assures longest life with positive sealing.
  • Seal retainers keep inner and outer sealing surfaces in precise position for maximum reliability and efficiency. Combined with the non-compressible seal rings, Power- Master valve retainers eliminate tolerance build-up in the free stack height of both retainers and seals.
  • Free-floating piston with extra large surface area means faster response at lower pressures.
  • Manual non-locking overrides allow supplementary manual control an permits operating the valve when the electric power is off.
  • External pilot allows an independent air supply to be connected to the pilot port in the valve operator or subplate for air pilot pressure.
  • Wire leads of 24" allows simplified conduit wiring.
  • Solenoid coil removal. Unscrew hex nut and slip off the solenoid housing and coil.
  • Exhaust restrictors can be used in either or both exhaust port to provide speed control of cylinders. (Refer to Accessory Valve catalog SC-400.)
