Directional Control Valves

TR ENGINEERING INCORPORATED Directional Control Valves - DC Series

TR Engineering’s DC Series directional control valves are ideal for applications where extremely low leakage and high reliability are mandatory. They are widely used for ground support and hydraulic systems.

DC Series Valves

Three Position, Detented, 4-Way Valves (Except 2-Way)
Constructed of heat-treated aluminum and alloy steels
Special seal designs to eliminate pressure loss when shifting from one position to another
Extremely low inter port leakage
Normal operating temperature range is -40 degrees F to +160 degrees F with standard nitrile seals
CV factor of .9
Back pressure should not exceed 250 PSI for satisfactory operation
For the manifold version, valves are supplied with 3/8″ – 16 high-strength mounting bolts
DC Series valves weigh approximately 2½ pounds each.
Panel Mountable

NOTE: Mounting is not a standard pattern.

Special Options

2 Position Detent (No Center): Add -D to the end of the model number
Stainless Steel Construction: Contact us for details
Low-Temperature Options: Contact us for details
10000 PSI Pressure Rating: See DCH Series Page for details
15000 PSI Pressure Rating: See DCXH Series Page for details
