Dezurik Swing Check Valves

Dezurik/APCO/Hilton carries a full line of check valves for Municipal and Industrial applications.

The Dezurik/APCO outside lever and weight swing check leads the charge by being the most popular and effective wastewater valve on the market. Thousands of Dezurik/APCO swing check valves are installed throughout New York and New Jersey with particular success in the most difficult of applications including New York City Department of Environmental Protection (NYC DEP facilities), Passaic Valley Sewerage Commission, and many others.

All APCO Swing Check Valves (CVS-6000/6000A, CVS-250/250A and CVS-EDV) are used to prevent the backflow of fluid by closing before flow reversal, thereby preventing slam and water hammer.

APCO Swing Check Valves have been successfully installed in clean and dirty applications including sewage treatment, water treatment, water distribution, industrial water and wastewater services. The designs meet or exceed the current revision of AWWA standard C508.

They are heavily constructed, full waterway flow area, premium design with multiple features and options with service life measured in decades, not years.

Capitalizing on the Swing Check design Dezurik developed the SmartCHECK pump control valve. By combining electric actuation and the fail-safe characteristics of the swing check the SmartCHECK valve is the most technologically advanced valve in its field.

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 check valve.

It is the valve you need when you want to control pressure surge during pump startup and shutdown, and close when the pump stops – even during a power outage. The electric motor actuator eliminates the need for hydraulic actuation providing the most economical solution, the lowest cost of ownership and the least maintenance.

There are no pressurized hydraulic oil lines to leak, no solenoids or strainers to maintain, and no hydraulic power unit is required. The ability to control normal opening and closing speeds to achieve surge free operation with a maintenance free electric motor is group breaking when combined with the ability to operate as a traditional swing check during power failure to protect important equipment.

APCO CVS-6000/6000A Valves available in sizes 2-66” (50-1700mm), can be rated up to 640 psi CWP (4400 kPa) and are available with ANSI Class 125/150 or Class 250/300 flanges. They are constructed with a heavy ductile iron body. Closure control devices include Air Cushioned Cylinder, Oil Controlled Cylinder, Bottom Mounted Buffer, Lever & Spring and Lever & Weight. In addition, the CVS-6000/6000A may be ordered as a convertible model that allows field conversion of the closure device.

APCO CVS-250/250A Valves available in sizes 2-42” (50-1100mm), are rated to 250 psi CWP (1725 kPa) and are available with ANSI Class 125/150 flanges. Constructed with a heavy cast or ductile iron body. Closure control devices include Air Cushioned Cylinder, Lever & Spring and Lever & Weight.

APCO CVS-EDV Valves available in sizes 3-30” (80-750mm), are rated to 250 psi CWP (1725 kPa) and are available with ANSI Class 125/150 flanges. They are constructed of NSF epoxy lined and coated 12 mil Dry Film Thickness (DTF) ductile iron bodies and covers. Closure control devices include Air Cushioned Cylinder, Lever & Spring and Lever & Weight.

SmartCHECK Pump Control Valves are available in sizes 4-20” (100-500mm). They are constructed of ASTM 536 ductile iron with 17-4 PH stainless steel shaft. The disc seat is durable Ultra High Molecular Weight Polyethylene (UHMW-PE) for extended life. The body seat is Type 316 stainless steel. Flanged ends are faced and drilled per ASME B16.1 class 125 or 250, ASME B16.42 class 150 or 300.
