Closed Type Goggle Valve

Closed type goggle valve has an open designed structure with fully closed shell, which has zero leakage during operation. It has a good resistance to the external force of the pipeline. The hydraulic actuators are set outside, it’s easy to operate & maintain & check at work site. This valve has the characteristics of multi-point synchronous clamping equipment, has good sealing performance, reliable operation, convenient maintenance, etc.
