78-31100 Pneumatic butterfly control valve

Overview

78-31100 Pneumatic butterfly control valve is a low-load butterfly valve.

It is mainly suitable for the flow and pressure control of low pressure medium. It is made up of the valve part. It is composed of two parts, gear and rack-type double-piston pneumatic actuator. The series Butterfly valve has the characteristics of simple structure, convenient operation, light weight, etc., and can be widely used for automatic control in petroleum, chemical, metallurgical, power station and light industry industries and remote control.

Main feature

78-31100 Pneumatic butterfly control valve adopts steel plate welding structure,

The valve part is divided into two types: open type and back seat type according to its structure.It has no valve seat structure, so the leakage is large. The rear seat type is an open structure,The valve seat is added to the foundation, so its leakage is larger than that of the open structure improve. The bonnet type is divided into two types: standard type and outer bearing type, standard type is applicable.For calibers below DN500, the outer bearing type is suitable for calibers above DN600. The actuator adopts imported gear, rack and pinion double-piston pneumatic actuator, It has the advantages of large and stable output, light structure and light weight.
