F643X Pneumatic Blind Valve product details

F643X Pneumatic Blind Valve product uses

F643X Pneumatic Blind Valve produced and sold by Baigang valve group,This series of blind valve according to GB6222 "Industrial Enterprise Gas Safety Regulations" while digesting and absorbing the relevant domestic and foreign advanced technology, based on their own research and development of a new generation of products. Widely used in industrial and mining enterprises, environmental protection industries such as gas, toxic gas pipeline media, as a reliable cutting device. 


F643X Pneumatic Blind Valvestructural characteristics  

1, the valve by the valve body, fan valve plate, stainless steel bellows, drive, clamping devices and other components; 

2, the valve body with three-point locking fan valve structure; 

3, the sealing parts of stainless steel and rubber seals, reliable sealing performance, thereby increasing the service life of the seal, the seal is located on the valve plate, easy to replace the seal for maintenance;

4, the actuator operation, work smoothly, opening and closing flexible, reliable action; 

5, clamping action using screw nut clamping, self-locking is good; 

6, Blind valve with a stainless steel bellows, with flexibility, long service life and so on. 


F643X Pneumatic Blind Valve installation and use rights

1, the valve is installed, the bracket should be fixed valve base, the valve force in the action on the bracket; 

2, first start the clamping device to the left and right valve body displacement so that the valve body and valve plate completely separated, and then open the valve plate drive to open or close, and then restart the clamping device, check the valve body is stuck on the valve body And whether the limit switch is activated when the drive is operating. 


F643X Pneumatic Blind Valve product introduction

The pneumatic blind valve is mainly composed of the left valve body, the right valve body, the valve stem, the gate, the sealing ring, the pneumatic push rod and other components, and the base and the support column form a rigid structural body. Sealing parts with stainless steel and rubber seals, good sealing performance, long service life, the seal set on the gate, easy to replace the seal when the seal, rubber seals with clamp in the gate. Pneumatic putter blind valve can be a single long-distance control, remote control can also be more than one network, under normal circumstances can also use the valve itself device manual operation. 


F643X Pneumatic Blind Valve working principle

1, the valve opens to the valve closed:

Clamping motor action, driven screw for counterclockwise rotation, the valve body loose in place (indicator light display), the drive motor action, drive the counterclockwise rotation of the gate in place, the gate closed in place (indicator display), clamping motor Action, driven screw clockwise rotation, body clamping in place (indicator shows) to complete the valve from opening to closing the entire process. 

2, the valve is closed to open: 

Clamping motor action, driven screw for counterclockwise rotation, the valve body loose in place (indicator light display), drive motor action, drive the gate clockwise rotation, the gate open in place, (indicator light) To open the whole process.
