Electric ultra-high vacuum flapper valve

CCD type-electric ultra-high vacuum flapper valve

The CCD electric ultra-high vacuum flapper valve drives the valve stem through an electric device to drive the valve plate to move up and down to open or close the vacuum valve . The valve is used to connect or cut off the air flow in the vacuum pipeline. The applicable medium is pure air and non-corrosive gas. With feedback signal device.

The switch part of the electric flapper valve is a gate, which has a simple and compact structure and an appropriate design. Before installing the electric flapper valve, a visual inspection must be carried out. The factory nameplate of the electric flapper valve should meet the requirements of the national industry standard "General Gate Valve Marking" GB12220. For gate valves with a working pressure greater than 1.0 MPa and disconnected on the main pipe, the compressive strength and strict characteristics test should be carried out before installation, and the application should be carried out after the qualified side. During the compressive strength test of the electric flapper valve, the test working pressure is 1.5 times the pound level, and the delay time is greater than 5 minutes. There should be no leakage of the gate valve housing and filling materials.
