Valtorc’s has released a new actuated dribble control ball valve series that is constructed with a high quality stainless steel ball valve, spring return/double acting pneumatic actuator and two (2x) Valtorc solenoid valves. Two voltage sources power solenoid valves while the spring return actuator supplies the package with a clean air source.
Valtorc Dribble Control Ball Valves are available in sizes ranging from 1/2” to 6”. Available end connections include Threaded, Socket Weld, Butt Weld and Flanged. There is a two stage positioning of the valve comprised of solenoid, actuator and specially configured limit switch. The filling vessels are able to reduce flow rate at a given point during a filling operation to more accurately fill a vessel. The flow dampening is able to rapidly partially close and then completely close, which reduces water hammer and shock to pipes and valves.
The new valves also features dual flow positions for filling vessels or flow dampening, along with fully adjustable set points allow the user flexibility to determine proper stage switching. There are open/closed limit switches that provide additional valve end point monitoring.
