Double flange cement dn300 butterfly valve



 Pneumatic powder cement dn300 butterfly valve is mainly used in the switch box, hopper,

and is equipped with powder or particle material silos. Can be applied to all processing of powdery and granular materials, Valve pneumatic transmission using the material to retain its own gravity and the dry material valve pneumatic transmission using the material to retain its own gravity and the dry material;


♦ Outline size drawing and size data:

 ♦ Double acting pneuamtic actuator:



 Double acting working principle:


When air pressure from the port (2) into two piston cylinder between central cavity, make the two


ends to the cylinder piston separation direction, both end air cavity air through the port (4) discharge,


and at the same time, make the two piston rack synchronous drive the output shaft (gear) counter-clockwise. And air pressure from the port (4) into the cylinder ends air cavity, two pistons to cylinder


intermediate direction, and the middle gas cavity air through the port (2) discharge, and at the same


time, make the two piston rack synchronous drive the output shaft (gear) clockwise.


• (if the piston relative inverse direction installation, output shaft that into reverse rotation)
