DeZURIK APCO SmartCHECK valve controls pumps
deZURIK, Sartell, MN, says its APCO SmartCHECK pump control valve has integrated swing check and electric motor operator so that it combines the functionality of a full-featured pump control valve with the best features of APCO’s CVS-6000 swing check valve.
It is designed to control pressure surges during pump start-up and shut-down, 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, says the company.
There are no pressurized hydraulic oil lines to leak, no solenoids or strainers to maintain and no hydraulic power unit is required.
SmartCHECK pump control valves are available in sizes 4-20-in. They are constructed of ASTM 536 ductile iron with 17-4 PH stainless steel shaft. The disc seat is 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.
