VAL-MATIC'S SWING CHECK VALVE OPERATION, MAINTENANCE AND INSTALLATION INTRODUCTION Val-Matic's Swing Check Valve has been designed to give many years of trouble free operation. All parts are inspected prior to final assembly to insure complete interchangeability of parts.
VAL-MATIC'S SWING CHECK VALVE OPERATION, MAINTENANCE AND INSTALLATION VALVE CONSTRUCTION The Swing Check Valve housing consists of a body section having integrally cast inlet and outlet flanges. The top portion of the body has a large integrally cast flanged access port, to which the top access cover is bolted. The size of this access port permits full access to the disc and seat components for maintenance or replacement.
VAL-MATIC'S SWING CHECK VALVE OPERATION, MAINTENANCE AND INSTALLATION disc has a chance to react to the diminishing forward velocity of the water, the disc will be driven to the closed position by the rapid flow reversal. Depending on how fast the reversal of flow takes place, a water hammer of different magnitudes will develop. The valve is available with an adjustable lever and weight, an optional and adjustable lever and spring assembly and a side mounted air cushion.
VAL-MATIC'S SWING CHECK VALVE OPERATION, MAINTENANCE AND INSTALLATION adjustments may be necessary depending on the valve’s optional equipment configuration and the installed system performance. TABLE 2. FLANGE BOLT TARGET TORQUE Valve Size (in) Bolt Dia.
