Product Description

GIQ High Vacuum Butterfly Valve With Pneumatic Actuator

The valve is suitable for non corrosive saturated steam and low vacuum pipeline, as closed circuit equipment. The valve seal butterfly valve, 0.25MPa pressure sealing butterfly valve at both ends of the shaft seal, ensure that the shaft seal does not leak. The structure of the NKD941X-25C type double seat seat and between the situation, both at the shaft end is screwed with rubber pressure water (pressure 0.25MPa) combined sealing situation. If necessary, electric heating assembly can be installed on the valve body.
