The VicCheck valve utilizes a springassisted singledisc design that achieves a leakfree seal with as little as 5 ft15 m of head pressure The valve can be installed in both horizontal and vertical positions Series 716H716 check valves are engineered The graphical symbol for these valves is a springloaded ball and a seat as shown below Direct operated Free flow No flow A light spring holds the valve poppet in its normally closed position The valve starts to pass fluid at a pressure equivalent to The smooth nearlyconstant area internal passages allow for high capac ity 64258ow with minimum turbulence When the 64258ow ceases or is reversed the piston closes slowly preventing pressure surges The nonslam design is also effective in dampening pu They are supplied to meet a wide variety of applications with the closing element in the piston ball or swing type Piston check valves are normally supplied by OMB with the addition of a spring which allows both the vertical and horizontal installat The inlet and outlet flanges are normally marked on t he pump but if the word inlet or outlet is not visible on the pump body you can also determine which end is the inlet by noting that the two fl anges have different lengths The length of the flan 1 520L0588 LWINNPPPINLWINYPIN PPNLY Quick reference Quick reference Atmospheric Vent Model No Cavity Description Flow Pressure Page AT M P103 325 Counterbalance Valve PIN LIN LIN PI Atmospheric Vent Model No Cavity Description Flow Pressure Pa Upper End Theory and Service.

Valves can provide on-off service only, allow different flow rates, relieve excess pressure , or prevent reversal of flow.. There a four ways to control the flow through a system – moving a disc or plug into or against a passageway, sliding a flat, round surface across a passageway, rotate an opening inside the shaft across the passageway, moving a flexible material into the passageway. 19Check valve with hydraulic operationConnecting threads M18x15 - 1815 M26x15 - 2615 DESCRIPTIONORDERING CODEModification PLAST-O-MATIC VALVES INC1384 Pompton Avenue Cedar Grove New Jersey 07009973 256-3000 Fax 973 256-4745 wwwTHREE-WAY AIR-OPERATED MINIATURE VALVES1384 Pompton Avenue Cedar Grove New Jersey 07009973 25 Operation. . and Maintenance. 2.
