Structural characteristics
Diaphragm valve is a special type of globe valve.
1. the opening and closing part of the elastic seal ensures that there is no internal leakage.
2. the streamlined flow path makes the pressure loss small.
3. there is no stuffing box, so there is no leakage.
4. The valve body and cover are separated by the middle diaphragm, so that the valve cover above the diaphragm, the valve stem and other parts are not eroded by the medium.
5. the diaphragm can be replaced and the maintenance cost is low.
6. The variety of lining materials can be applied to various media, and has the characteristics of high strength and good corrosion resistance.
EG6B41J pneumatic normally closed type rubber-lined diaphragm valve, EG6B41J-10, EG6B41J-6 type rubber-lined valve is used to change the channel section and the direction of media flow, with diversion, cut-off, adjustment, throttling, check, diversion or overflow functions. Valves can be used to control the flow of water, steam, oil, gas, mud, various corrosive media, liquid metals and radioactive fluids and other fluids.

Note:
1. Pneumatic diaphragm valves can also be equipped with feedback signals, limiters or positioners to meet the needs of self-proximity control, program control or flow regulation.
2. The feedback signal of pneumatic valves is non-contact sensing technology.
3. Adopt cylinder piston type.
4. When the gas source fails, the handwheel can be operated to open the valve.
