16 Tyco/Check Valve Wafer Checkvalve Figure 85 Checkvalves, to control flow direction Features • The compact wafer thin body provides extreme low weight. • Minimum width of body allows installation between various flange standards. • Seating O-ring placed in dove-tail groove of disc is easily replaceable. • Low pressure shut-off. This check-valve offers positive shut-off even ar very small differential pressure, due to rotational axis location. Disc weight acts to fully close valve.
Check valves are vital components of many systems. Their purpose is simple: to prevent the reversal of flow rather than stopping, starting, or throttling flow. Reverse flow may be merely a nuisance, or it can cause severe damage to equipment contamination of potable water supplies, or hazardous conditions resulting from the uncontrolled mixing of various fluids in pipelines.
