Check Valve Accessory

The Rite Series SA-50 Hydraulic Pneumatic Speed Controls slow down the opening of the valve to protect the disc assembly in the last few degrees of travel. These units offer adjustable speed control and are ideal in fluctuating flow applications. The SA-50 uses the SA-40 compression spring. (Note: Another version of this speed control, the Model H-100, is available using the SA-01 compression spring.)
