Product Name: Central Line Soft Seat Wafer Pneumatic Butterfly Valve

Product introduction:
With simple structure light weight quick opening speed pneumatic wafer switch butterfly valve consists of the piston type cylinder and the wafer type butterfly valve and the spring return type valve can support automatic reposition function (air to open and close) when the air and power were cut off.
This product is widely applied in the industrial pipeline fields of metallurgy environmental protection water treatment petrochemical power.
*Small volume and light weight easy to disassemble and maintain and can be installed in any position
*Less pressure drops Large flow capability
*Small operating torque energy saving
*Linearity flow characteristics，Excellent regulated performance
*Simple and compact structure
*Long service life good seal performance

PRODUCT CHARACTERISTICS

*pneumatic piston actuator is divided into two types of spring-type and spring-free type. When the valve is required to be fully opened or closed under fault it is equipped with spring type (by restoring tension of spring). When it is required to maintain position under fault it is equipped with no spring type.It is mainly composed of cylinder body spring piston piston rod front and rear cylinder head rack output shaft and other components.
*Equipped with travel limit switch solenoid valve filter pressure-reducing valve and other accessories and 0.4-0.7mpa air source the switch operation can be realized.
The switch signal of industrial automation control system can be received to accurately control the valve opening so as to achieve the control of flow temperature pressure and other different process parameters.
