application
This type of valve series is a manually operated butterfly valve series, because it can be a very good deal with viscous or medium containing particulate matter, which is widely used in food and beverage processing, as well as within the pharmaceutical and chemical industry pipeline system adjustment and control medium flow of the valve.
The working principle of
This type of valve either through an electric actuator or a pneumatic actuators for remote control operation, also can be the manipulation by a handle.
Electric actuators or pneumatic actuator is an axial movement of the piston into the rotation of the valve shaft 90 ° to achieve open or closed, the control system for the pipeline fluid and the on/off task. There are three kinds of pneumatic actuator device standards normally open (NO), normally closed (NC), gas/gas (A/A).
Rod type manual handle through four functional positioning, mechanical locking in the open or close the valve of four seat, also achieve the goal of control medium flow.
