Lined stainless steel diaphragm valve
Other Products
I. Introduction:
The G41F4 fluorine-lined stainless steel diaphragm valve separates the lower cavity of the valve body from the inner cavity of the valve cover, forming a straight flow passage. This completely isolates the inner parts such as the valve stem and valve disc above the diaphragm from the medium, eliminating the need for a packing seal structure and preventing both internal and external leakage of the medium. The diaphragm, which serves as the membrane element of the stainless steel diaphragm valve as an actuator, is prone to fatigue fracture due to frequent opening and closing. It should be replaced regularly according to the working conditions and medium characteristics. For the corrosion resistance and recommended operating temperature of plastics, please refer to the "Performance Table for Plastic Linings of Valves and Pipeline Accessories". This valve is composed of a valve body, valve cover, valve disc, valve stem, diaphragm and other driving parts. The opening and closing of the valve are achieved by rotating the handwheel. At the upper end of the valve cover of the diaphragm valve, there is a display color that allows the opening or closing position of the valve to be seen, indicating the opening and closing stroke of the valve. When the handwheel is turned clockwise, it moves downward, and the valve disc drives the diaphragm down to cut off the passage; conversely, the valve opens and the display color is revealed.
II. Features:
1. The stainless steel diaphragm valve adopts a structure without a packing box; the diaphragm of the G41F46 fluorine-lined diaphragm valve completely isolates the corrosive medium in the flow passage from all driving parts, thus eliminating the common drawbacks of valves such as "run, emit, drip and leak".
2. Due to the smooth flow passage and small flow resistance of the diaphragm valve, a large flow rate can be obtained.
3. The inner cavity of the valve body of the fluorine-lined diaphragm valve is lined with perfluoro F56, so it has excellent corrosion resistance.
4. Since the sealing element is an elastic PTFE diaphragm, it also has good sealing performance and a small closing force.
5. This valve is composed of a valve body, valve cover, valve disc, valve stem, diaphragm and other driving parts.
6. The opening and closing of the valve are achieved by rotating the handwheel. At the upper end of the valve cover of this valve, there is a display color that allows the opening or closing position of the valve to be seen, indicating the opening and closing stroke of the valve. When the handwheel is turned clockwise, it moves downward, and the valve disc drives the diaphragm down to cut off the passage; conversely, the valve opens and the display color is revealed.
7. This valve adopts the standard: in accordance with the provisions of GB12239.
