Check Valves

SmartCHECK Pump Control Valves have an integrated swing check and electric motor operator that combines the functionality of a full-featured pump control valve with the best features of APCO’s CVS-6000 swing check valve. It is the valve you need when you want to control pressure surges during pump startup and shutdown, and close when the pump stops — even during a power outage.

APCO Swing Check Valves prevent back flow of fluid by closing before flow reversal, thereby preventing slam and water hammer. These industrial swing check valve designs meet or exceed the current revision of AWWA standard C508.

Double Door Check Valves automatically prevent back-flow and slam. They have a cost-efficient design, short laying length, low weight and are easy to install.

Rubber Flapper Swing Check Valves feature a simple design with only one moving part. The flapper opens to a straight unobstructed flow passage. Because the seat is on a 45° angle, the flapper travels only 35° from open to closed, usually before column reversal can occur. It has non-slam characteristics, requires no regular maintenance, and can be installed in either horizontal or vertical flow-up installation.

Silent Check Valves prevent water hammer by positively closing before reversal of flow can occur. The valve closes silently, is low in cost, reliable and requires no regular maintenance. Silent Check Valves are commonly used in vertical turbine pump installations when pumping from a well to an elevated reservoir. They are also recommended for commercial and industrial HVAC applications such as heating systems and condensate return lines.

Slanting Disc Check Valves are ruggedly designed with superior flow characteristics, minimal head loss and maximum slam resistance. Slanting Disc Check Valves are the most reliable and efficient check valves available. They are ideally suited for clean municipal/industrial water and other industrial liquid applications.

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 single centrifugal pump. APCO Full Flow Foot Valves are designed to have the high quality, long wearing construction necessary for valves that are continually submerged in a wet well and that are not readily accessible for inspection or repair.

Full Flow Rubber Flapper Foot Valves are designed for water or sewage and are suitable for submerged service. The Full Flow Rubber Flapper Foot Valve is installed in the vertical position with the direction of flow in the upward direction. In this position the Foot Valve is normally closed. The Foot Valve opens while the centrifugal pump is running and closes when the pump stops running to maintain a flooded suction and primed pump.
