DVD 790 Burst Control Valves are designed to minimize wasting of water, land erosion and the damage that can be caused by pipeline failures or equipment malfunction. Burst Control Valves senses the flow in excess of setting. In case of a pipeline burst, the valve senses high flow and shut off drip tight and lock closed until manually reset. The defined maximum 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.
