Product Name Notes
All APCO Swing Check Valves (CVS-6000/6000A, CVS-250/250A and CVS-EDV) are used to prevent the back flow of fluid by closing before flow reversal, thereby preventing slam and water hammer. APCO...
APCO CSC Silent Check Valves are designed to prevent water hammer by positively closing before reversal of flow can occur. The valve closes silently, is low in cost, reliable and...
DeZURIK Pump Check Valves are used to reduce the possibility of water hammer throughout the system by controlling valve opening and closing speeds so the operation does not cause pressure...
Double Door Check Valves are designed to automatically prevent back-flow in systems where it is desirable to permit flow in one direction and prevent flow in the opposite direction. Double...
Full Flow Foot Valves can be installed at the bottom of a pump suction line, inside the wet well. Foot valves are an inexpensive way to maintain prime on a...
Full Flow Rubber Flapper Foot Valves are designed for water or sewage, and are suitable for submerged service. The Rubber Flapper Foot Valve is installed in the vertical position with...
Rubber Flapper Swing Check Valves feature a unique, simple design with only one moving part. The flapper does not swing from a hinge pin; it simply flexes open. The seat...
The H-700 Vertical Check Valve is designed for vertical flow (not suitable for down-flow applications). The disc shaft is fully guided to insure proper alignment between disc and seat. The...
The H-900 is designed for horizontal or vertical flow with a large flow area (not suitable for down-flow applications). The angled seat reduces disk travel from full closed to full...
The H-920 is designed for horizontal flow. The narrow face to face saves room in piping systems and the disc stop prevents interference between the disc and downstream piping. The...
The H-950 Swing Check Valve is designed for horizontal or vertical flow (not suitable for down-flow applications). When fully open the valve disc is out of the flow area allowing...
The SmartCHECK Pump Control Valve with integrated swing check and electric motor operator combines the functionality of a full-featured pump control valve with the best features of APCO’s CVS-6000 swing...
The Surge Check Valve is designed for installation to the inlet of the existing Air/Vacuum Valve on the line. It consists of a body, seat, flow-disc and compression spring. The...
The Tilting Disc Check Valve is designed with the shaft close to valve centerline which balances the disc so that the valve will open at a low pressure differential. O-ring...
With decades of experience to guarantee reliability and outstanding performance, APCO CSD Slanting Disk Check Valves are ruggedly designed with superior flow characteristics, minimal head loss and maximum slam resistance.
