Flow Control Valve, Adjustable, 1/4 in Nominal, -40 to 212 °F, 1-3/4 in W Dimensions

A spring biased ball or optional poppet check provides full flow in 1-direction. A stainless steel, tapered needle provides a wide range of adjustment of flow in the controlled direction. A locknut prevents unwanted changes in adjustment. This control allows higher air pressure for maximum torque capacity while achieving a "soft" start or stop through a gradual pressure build-up in the clutch or brake air chamber. Controlled acceleration or deceleration ("soft" start or stop) can also be incorporated into a clutch/brake circuit similar to the 3-way circuit diagram shown on page 351, by adding a flow control, quick exhaust valve and accumulator between the control valve and the clutch/brake unit.
