The RPV 10-32 ports, adjustable rapid pressurization valve from Beswick Engineering is used to protect a pneumatic actuator such as a chuck, press, or gripper from sudden bursts of high pressure. The internal needle valve restricts the initial movement of the actuator to a user defined speed, and then opens up upon sensing back pressure. This allows the user to limit the impact that a work piece experiences when it is clamped down upon without sacrificing the pressurization speed of an open, free flowing connection.
In an application with a pneumatic clamping device like a chuck. Ideally you want the jaws of the chuck to move slowly until the jaws touch the surface of the workpiece. That can be accomplished with a simple restrictor. But, as soon as the jaws contact the workpiece, the user may need to trigger a rapid increase in the supply pressure to provide maximum clamping force. A simple restrictor cannot do that.
There are two user adjustable settings provided in the RPV which allow the user to limit the impact a workpiece experiences when it is clamped down upon without sacrificing the pressurization speed of an open, free flowing connection.
It is rated for maximum pressure of 250 psig. The corrosion resistant 302 and 303 stainless steel valves come with 10-32 UNF female threaded ports.
