DVD 740 Pump Control Valves are designed to protect pumps, pipelines and other system components by isolating the pipeline from sudden velocity changes associated with pumps starting and stopping. The “Active Check Valve” logic of operation is the method of pumping system control that prevents surges before happening, rather than eliminating them. With the solenoid – limit switch assembly, the valve communicates with the pump. In pump start, first the pump starts, and that the valve opens gradually, providing flow in a controlled manner. In pump stop, first the valve closes slowly, and that it sends a signal to stop to the pump. DVD Control Valves are hydraulically operated & diaphragm actuated Y pattern valves. Due to Y pattern body, they have higher kv values and lower pressure loss values compared to globe valves. They consist of a body and an actuator assembly. The actuator assembly can easily be dismantled from the body as a whole, without removing the valve from the line, and can be converted to/from single from/to double chambered actuator on site to the needs of the project. DVD Control Valves are manufactured as standard from GGG40 Ductile Iron material.
