The APCO SmartCHECK Pump Control Valve from DeZURIK combines the functionality of a full featured pump control valve with the best features of APCO’s premium 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. SmartCHECK valves are ideal for applications such as raw sewage, wastewater, dewatering, raw water, clean water or any fluid pumped through a pipeline.
The secret to how this valve works is in its simple and unique torque unit. The torque unit allows the valve to function normally as a motorized pump control valve, except the valve closes automatically and without actuation upon power loss. If power is lost, SmartCHECK prevents damaging backflow, pump back spin, system drain back and flooding of the sump. 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.
SmartCHECK has an internally pressure balanced design that will reliably close every time upon emergency flow reversal. Unlike piston or globe style pump control valves which can fail open on an emergency power failure because of their unbalanced designs, SmartCHECK closes reliably when needed. In addition, headloss-producing springs to assist closure are not necessary on the SmartCHECK valve and it can always be set to operate at its full open position without fear of ‘sticking’ open.
