DVD 730 Pressure Relief / Sustaining Valves are designed to protect pumps and water distribution systems from two extreme situations. When installed off-line, they relieve damaging excessive pressure. When installed in-line, they sustain minimum back-pressure thus prioritizing pressure zones, preventing line emptying & pump overload etc. They are not affected by varying flow or varying downstream pressure. The defined upstream pressure 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.
