The BiS range of 4 port directional valves include both balanced poppet and rotary shear seal designs, commonly used to give control of double acting actuators.
The 4R series valves are lever operated 2 or 3 position rotary valves offering 90° manual actuation, in both detented and non-detented configurations, and with a range of centre conditions. They may be used in many different installations, with standard threaded porting, directly mounted on manifolds, or mounted behind panels.
When manual control is not required, the 6B range of 2 position 4 way valves offer other methods of actuation, such as hydraulic and pneumatic pilots.
