QT450 Pneumatic Lug Butterfly Valve - Ductile Iron/WCB/EPDM Specification QT450 Pneumatic Lug Butterfly Valve Pneumatic actuator can be selected as single acting or double acting, and other accessories can be selected, such as adjusting positioner, limit switch, air direction control valve (air solenoid valve), air filter regulator.
The manufacturer of pneumatic lug butterfly valve belongs to the elastic seat butterfly valve, a type of medium line butterfly valve that can be made into standards such as Class150, JIS10K, EN PN16/PN10, etc. A handwheel operating device can also be installed to drive the valve through air, and it can also be manually opened and closed.
Equipped with limit switches, air directional control valves (air solenoid valves), and air filter regulators. 
Handwheel Operating Device Pneumatic Lug Butterfly Valve - Limit Switch/Air Direction Control Valve Pneumatic Lug Butterfly Valve After installing the pneumatic reversing valve, the direction of the airflow driven by the pneumatic reversing valve is switched to control the opening and closing of the valve.
We will match high-quality pneumatic valve actuators for the selection of pneumatic lug butterfly valves with air directional control valves. Single acting or double acting valves can be selected, and there are also multiple options for valve body materials, valve plate materials, and valve seat materials

Pneumatic actuator
Dual function: ventilation on, ventilation off, maintain current position in case of gas source failure
Single acting gas on type: ventilation on, gas off, gas source failure off
Single acting gas cut-off type: ventilation cut-off, gas cut-off, gas source failure opening
The pneumatic lug butterfly valve is equipped with a dual acting pneumatic actuator and a limit switch, which can remotely feedback the valve position signal (open or close). After installing the locator, it can receive or output 4-20mA/0-10V analog signals to adjust the valve proportionally. Equipped with an air filter regulator to adjust the intake air pressure and filter out moisture in the air; In addition to pneumatic lug butterfly valves, automatic valves also have electric lug butterfly valves to choose from.
