Product Name Notes
All APCO Swing Check Valves are used to prevent the back flow of fluid by closing before flow reversal, thereby preventing slam and water hammer. APCO Swing Check Valves have...
APCO CRF-100C/100 Rubber Flapper Swing Check Valves are uniquely simple in design but durable for use on a variety of applications. The valves are engineered and tested to meet the...
APCO CSC Silent Check Valves are designed to mitigate water hammer by positively closing before reversal of flow can occur. The valve closes silently, is low in cost, reliable and...
APCO 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.
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...
In some applications, a Slip-on Tideflex® Duckbill Check Valve (TF-1) is not feasible because of an existing mating flange or wall thimble, or a flanged connection is preferred, or...
Manufactured on the same principle as the revolutionary all-rubber Tideflex® Check Valve, the Series 2633 is a simple inline check valve for threaded end pipelines. Simple in design, the...
The APCO Surge Check Valve prevents critical shock conditions from occurring in installations where an Air Vacuum Valve could slam open or closed. The Surge Check Valve is bolted to...
The CheckMate® UltraFlex® Inline Check Valve works by preventing unwanted backflow that can cause surcharging and flooding. The valve minimizes damage to commercial, wetlands, beaches and residential areas.
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 disc travel from full closed to full...
The Hilton H-920 Wafer Swing Check Valve is designed for horizontal flow. The narrow face to face saves room in piping systems and the disc stop prevents interference between the...
The Hilton H-940 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.
The Hilton 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...
The Series 35 is manufactured similarly to the Series TF-2, with the addition of an integral elastomeric flange. The Series 35 can be mounted to mating flanges or wall thimbles...
The Series 37 Inline Check Valve is a simple, reliable, cost-effective solution for backflow prevention. The revolutionary design of the 37 is similar to the Series 35, but the Series...
The Series 37G is a special adaptation of the Series 37. The 37G can be completely inserted into a pipe which effectively gives it a zero face-to-face dimension. The outside...
The Series 37G Thimble Insert is comprised of a Series 37G Check Valve mounted in a thimble. The 37G is pre-assembled, clamped and pinned into the thimble prior to shipment.
