Manual plastic flange diaphragm valve

Product features: The most outstanding feature is that the diaphragm separates the inner cavity of the lower valve body from the inner cavity of the upper valve cover, so that the valve stem, disc and other parts above the diaphragm are free from medium corrosion, and the packing sealing structure is omitted, and the medium leakage will not occur.

Product introduction: Rubber lined diaphragm valve is a special type of block valve, which appeared in 1920s. Its opening and closing part is a diaphragm made of soft material, which separates the inner cavity of the valve body from the inner cavity of the valve cover and the driving parts, so it is called diaphragm valve. The most prominent feature is that the diaphragm separates the inner cavity of the lower valve body from the inner cavity of the upper valve cover, so that the valve stem, disc and other parts above the diaphragm are not corroded by medium, and the packing sealing structure is omitted, and the medium leakage will not occur.

Brief introduction of diaphragm valve: G6K41J normally open pneumatic rubber-lined diaphragm valve is a special form of shut-off valve. Its opening and closing part is a diaphragm made of soft material, which separates the inner cavity of the valve body from the inner cavity of the bonnet, so that the valve body, The valve clack and valve stem are not corroded by the medium, and no medium will be generated. The normally open pneumatic rubber-lined diaphragm valve is used to change the passage section and the flow direction of the medium, and has the functions of diversion, cut-off, adjustment, throttling, check, diversion or overflow. The valve can control the flow of water, steam, oil, gas, mud, various corrosive media, liquid metal and radioactive fluid.

Fluorine lined pneumatic diaphragm regulating valve (ZMATF-10K) Pneumatic diphragm control valve (ZMATF-10K) The ZMATF (pneumatic open) pneumatic diaphragm regulating valve and ZMBTF (pneumatic close) pneumatic diaphragm regulating valve are composed of a multi spring pneumatic diaphragm actuator and a diaphragm valve. The diaphragm valve body has smooth flow, the throttling element is an elastic diaphragm, and there is no stuffing box on the valve cover. Therefore, the flow capacity of the valve is larger than that of general regulating valves and there is no leakage, which can be used as a shut-off valve within the allowable pressure difference range. The air opening and air closing functions are achieved by the forward and reverse actuators. This valve is suitable for regulating high viscosity fluids, suspended particles, fibrous media, toxic media, and corrosive media.

The most prominent feature is that the diaphragm separates the inner cavity of the lower valve body from the inner cavity of the upper valve cover, preventing the valve stem, valve disc, and other parts located above the diaphragm from medium corrosion, eliminating the packing sealing structure, and avoiding medium leakage. 1. Diaphragms made of soft sealing materials such as rubber or plastic have good sealing performance. As the diaphragm is a vulnerable component, it should be replaced regularly based on the characteristics of the medium. 2. Due to the limitations of diaphragm materials, diaphragm valves are suitable for low pressure and relatively low temperature applications. 3. Diaphragm valves can be divided into six types according to their structural forms: roof type, direct flow type, globe type, straight through type, gate type, and right angle type; The connection form is usually flange connection; According to the driving method, it can be divided into three types: manual, electric, and pneumatic, among which pneumatic driving is further divided into three types: normally open, normally closed, and reciprocating. 4. It is generally not suitable for pipelines with temperatures above 60 degrees Celsius and transporting organic solvents and strong oxidizing media, nor for pipelines with higher pressures

This series of diaphragm valves can be applied to different fluid medium pipelines at different temperatures based on different coating materials, serving as an opening and closing mechanism to control medium flow.
