Application
DV series butterfly valve is a sanitary type, automatic or manual operation of the valve,all kinds of application suitable for stainless steel piping system.
Operational Principle
DV series valve can be through a pneumatic head remote operation, also can be operated manually by a handle.
The actuator has three kinds of standard models, which is normally closed (NC), normally open (NO) and air/air (A/A).
The actuator will convert the axial movement of a piston 90 ℃ rotating value shaft.Come into with contact with the valve sealing when circular disc value body.Ring the actuator torque increase, close the valve.
Select the handle of the manual operation of the valve can be mechanical locking in the open and close, intermediate or other location, achieving the realization of the flow.
