DVD 770 Flow Control Valves are designed to maintain a pre-set maximum flow rate regardless of variations in demand or upstream/downstream pressure. They have an orifice assembly on the line for sensing the differential pressure in varying orifice. The pilot changes the opening of the valve as a result of this sensing device. The defined flow rate can be easily set from the pilot of the valve. 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.
