Parker Speed King & Valvair II body ported four-way valves. have been trusted by the industry for years in applications requiring a heavy-duty, all-metal valve that will shift when called upon, even after being idle for an extended period of time. The solenoid/air pilot design of this valve uses line pressure to shift the spool. Single solenoid valves may be mounted in any position. Double solenoid valves should be mounted horizontally. Synthetic rubber o-ring seals are specially compounded for superior wear and abrasion resistance. Solenoids are encapsulated in epoxy for low power consumption and maximum life. These valves are very tolerant to contamination both inside and out.
