Hard Back Seat Pneumatic Single Flanged Butterfly Valve PN10
Basic Info of Pneumatic Single Flanged Butterfly Valve
Structure: the pneumatic single flanged Butterfly Valve has only one flange surrounding the middle of valve body.
The pneumatic actuator is a key component of the valve. It drives the opening/closing or regulating function of the valve through compressed air and is suitable for automation systems or scenarios requiring remote control.
Double-Acting: The actuator is switched on/off by air, without springs, suitable for systems that require frequent operation.
Pneumatic single flanged Butterfly Valve design is lightweight and compact, making it ideal for projects with limited space or budget
Compared with the double flange butterfly valve, the single flange butterfly valve reduces the weight and material of one side of the flange, reducing manufacturing and installation costs.
The hard back seat is used to enhance sealing capabilities, ensuring minimal leakage and reliable operation under pressure.
