Pneumatic lug type butterfly valve pneumatic actuator can choose single or double acting, and other accessories can be selected, such as: Positioners for adjustment, limit switch,Air directional control valve (air solenoid valve), Air Filter Regulator.
Pneumatic lug butterfly valve Manufacturer
It belongs to Resilient seated Butterfly Valve, a kind of concentric butterfly valve, which can be made into Class150, JIS10K, EN PN16/PN10 and other standards.It is also possible to add a handwheel operating device to become a valve that can be driven by air and can also be manually opened and closed.
Pneumatic lug type butterfly valve-limit switch/Air directional control valve
After the pneumatic lug butterfly valve is equipped with an Air directional control valve, the air flow direction driven by the Air directional control valve is switched to control the opening and closing of the valve.

Pneumatic lug type butterfly valve supporting functions
Pneumatic lug butterfly valve can remotely feedback valve position signal (open or closed) after being equipped with limit switch. After installing Positioners, it can receive or output 4-20ma/0-10V analog signal to adjust the valve proportionally. Equipped with Air Filter Regulator The air pressure of the intake air can be adjusted and the water in the air can be filtered;In addition to pneumatic lug butterfly valves, automatic valves also have electric lug butterfly valves to choose from.
