Pneumatic valve adjustment than infinite adjustment 3)

R. H。 Mr WEIKER first rubber plug type pneumatic control valve, to cater to the gas industry demand for low noise multipurpose, the rubber plug type pneumatic control valve universal access to the world. Then continue to do a lot of improvement and become today's WELKERJET pneumatic control valve. Characteristics: absolute shut off, wide soft sealing surface, even in welding slag, larger particles, can also be tightly closed. The minimum flow is absolute zero. Main pneumatic valve parts can connect directly acting alone, deserve to go up can also guide the pneumatic valve becomes indirect effect, can be operated by pneumatic control.
the main structure of pneumatic valve: it's clip and rubber tube of the principle of the pneumatic valve on the contrary, there is a streamlined hollow rubber plug is located in the middle of the channel, the rubber plug inside the hollow hydraulic medium, when the hydraulic medium pressure increases, rubber plug, the channel of the annular area is smaller, intercepting effect, medium pressure continues to rise, the rubber plug can be completely closed. Diaphragm and pneumatic valve stem of gas-liquid pressurization device, pressure for deformation of the rubber plug. From the motion of the diaphragm regulating the export of pneumatic valve feedback, with signal pipe connection. I don't know you understand not.
