GIQ High Pressure Vacuum Pneumatic Butterfly Valve

GIQ pneumatic high vacuum butterfly valve is to change the direction of gas path by electromagnetic reversing valve, and control the cylinder driven butterfly valve for opening and closing activities. Used to connect or cut off the air flow in a vacuum line. Applicable medium is pure air and non corrosive gas. Optional feedback signal assembly and electrical valve positioner.

Important technical performance
Applicability 105~1.3×10-4Pa
Valve Leak Rate ≤1.3×10-4Pa.L/S.
Applicable Temperature -25~+80ºC(Nitrile butadiene rubber)
-30~+150ºC(fluoro rubber)
Mains Voltage 0.4~0.6MPa
Mounting Direction optional

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.
