Directional Control Valves (Water / Oil Hydraulics)

Direct Acting (Face-Mounted) 2/2 and 3/2 Valves

2/2 and 3/2 direction control seat valve suitable for water, oil and air

These direct acting, face-mounted directional control valves are suitable for water and oil hydraulics control systems with working pressures up to 320 Bar. They are characterized by fast response times and seal using a ball seat valve.

Type Directional Control Ball Seat Valve
Face mounted with O-ring seal (connection plate available on request)
Thread connection sizes
NW3 = R1/4″ or 1/4″ NPT
NW6 = R3/8″ or 3/8″ NPT
MediumWater, oil or air (must be specified with purchase order)
Fluid Viscosity 1 to 300 cSt
Temp. RangeDepends on control element used (confirmed on request)
SealsNBR, other sealing materials available on request
SealingBall on Seat
Pressure Range0 to 320 Bar (630 Bar)
For 3/2 valves the pressure in connection “R” must not exceed 50% of the working pressure
Switching TimeDepends on operating pressure and temperature (confirmed on request)
Flow Direction2/2W: From “P” to “A”
3/2W: From “P” to “A” or from “A” to “R”
The connections “P, A and R” must not be mixed up
Flow Rate for LiquidsMax. 20 LPM at NW6
Max. 5 LPM at NW3
Operating ModesElectric, hydraulic, pneumatic, mechanical or manual operation
MaterialsAll parts in contact with the flow medium are corrosion resistant materials
Special FeaturesActuation magnet protected against dirt and humidity
Solenoid plunger protected against wear
Electromagnet and all other control elements can be rotated by 90 deg.
All wear parts are easily accessible and can be replaced quickly

Pilot Controlled (Face-Mounted) 2/2 and 3/2 Valves

These pilot-operated directional control valves are particularly suited to HFA liquids and clear water up to a maximum working pressure of 320 Bar. The valves can be equipped with positive or negative pilot operation, so that the in the de-energized condition, the main valve port can be “normally closed” or “normally open”.
