Pneumatic Operated Lug Butterfly Valve

INTRODUCTION

Product Advantages
1、The structure is simple and compact, the rotation of 90 °is quickly to open and close, and the service life is long. The side flange can meet the PN10, PN16, 150Lb and 10K flanges;
2、All products can provide the pressure test: All Yuming products can provide the pressure test report before leaving the factory.
3、High performance seat rubber: The rubber content is 50%, and the switch life is more than 30000 times
4、Axial seal: The shaft is supported by 4 oil-free bearings, double seal structure design of oil seal and O-ring, smaller torque and reliable seal; The upper and lower shaft holes of DN350 and above large diameter valves are designed with packing box structure, and the packing is pressed by the gland to realize sealing.
5、Surface coating: Epoxy powder coating is adopted, with strong adhesion and good weather resistance. It can be used indoors and outdoors.
6、Pneumatic Operated: The pneumatic operated adopts double piston rack structure, precise meshing, high efficiency and outputting constant torque. The cylinder body is made of extruded aluminum alloy with high strength and hardness. The sliding bearing is made of low friction materials, low friction coefficient, flexible rotation and long service life.
