G6B41J Normally open pneumatic diaphragm Valve Product Introduction:
The biggest difference with other valves is: the use of no stuffing box structure; The rubber diaphragm can make the corrosive medium in the flow channel completely isolated from all the driving components, thereby eliminating the usual valve "running, taking, dripping, leakage" and other drawbacks.
Because the flow path of the diaphragm valve is smooth and the flow resistance is small, a larger flow rate can be obtained. The surface of the inner cavity of the valve body of the diaphragm valve may be covered with a variety of rubbers for choice. Therefore, it has superior corrosion resistance. Because the seal is elastic rubber diaphragm. Therefore, it also has better sealing and minimum closing force.
It is composed of valve body, valve cover, valve disc, valve stem, diaphragm and other driving parts.
The opening and closing of the valve is achieved by rotating the hand wheel. The valve is marked on the upper end of the valve cover with the display color of the opening or closing position of the valve to indicate the opening and closing stroke of the valve. When the handwheel is placed clockwise, the handwheel is moved down, and the valve disc drives the diaphragm down to cut off the path; On the contrary, the valve is opened and the color is revealed.
