Valtorc introduces the unique Series DRB-500 Dribble Control Valve package.
Two-stage positioning of the valve comprises of solenoid, actuator and specially configured limit switch. Its filling vessels are able to reduce flow rate at a given point during a filling operation to more accurately fill a vessel and its flow dampening is able to rapidly partially close, and then completely close. This reduces water hammer and shock to pipes and valves.
The features include dual-flow positions for filling vessels or flow dampening, fully adjustable set points allow the user flexibility to determine proper stage switching, and open/closed limit switches provide additional valve end point monitoring. In addition, it is factory assembled and tested, saving users and assemblers’ time and money, part of the industrial grade Valtorc Stainless Steel Ball Valve series, has 2 solenoid valves and an actuator positioner.
Two voltage sources to power both Solenoid Valves (#1 and #2) are required, as well as, contact logic (2), which may be provided by flow meters, scales, level sensors, or PLCs, and spring return pneumatic actuator with a clean air source.
