◆Purpose

Pneumatic actuator gate valve has stable performance, easy to operate and convenience to maintain, are extensively used in petroleum industry, Chemical plant, and  sea transportation as a medium control facility. 

◆feature

1、 Pneumatic actuator gate valve has manual operated organ and pneumatic actuator organ.

2、has double cylinder,compare with single cylinder structure,the power doubled.

3、solve the disadvantage of single cylinder pneumatic actuator gate valve has, such as some disc cannot open when welded.

4、has buffer structure, can effectively reduce the abrasion in sealing face of disc and bonnet when close valve. It also can avoid block of disc.
