Solenoid pilot pressure must be a minimum of 25 psi with return springs, 15 psi less return springs and a maximum of 150 psi. A flush, non-locking manual override is standard for manual operation when the electric power is off. Other optional features are available upon request such as high pressure (200 psi) solenoids.

- Subbase mounted four-way valves for two and three position (spring centered) closed center operation and a selection of three operators.
- Three-way function can be obtained by plugging one delivery port to provide either normally open or closed operation.
- Unique subbase is designed to be mounted to the customer’s equipment with only two mounting bolts, which saves labor and material during installation.
- Separate tapped exhaust ports, in the subbase, for each delivery port allow exhaust air to be piped away for safety or noise reduction purposes and permit use of exhaust restrictors for cylinder speed control.
- Minimum number of wearing parts. Lessens the chance of equipment downtime and reduces the cost of repair.
- Low pilot pressure. A low (15 psi without springs-25 psi with springs) pilot pressure rating assures reliable operation. Fluctuating line pressures within the plant do not affect operation.
- Continuous-duty solenoid. Won’t burn out...even when energized for extended periods. Pilot operated for fast response. Non-locking manual override is standard.
- Lightweight aluminum spool. Aluminum spool is precision finished for faster response and optimum dependability.
- Low friction spool bore. Bore is roller burnished for lower spool friction and longer seal life.
- No-leak seals. Specially treated Buna-N seals assure low friction and long wear without leakage.
- Easier maintenance. Simplified design offers quick access for maintenance through 3-bolt valve portion mounting and easy end cover removal.
- U.L. listed.
