Diaphragm itself operating temperature range and pressure range
depends on the types of plastic , fabric and structure. The
diaphragm can be operated at -50 to 100 ° C , 0.4 ~ 0.8MPa
conditions ; fluorine rubber and silicone rubber diaphragm 232 can
work in -80 degrees Celsius . Epichlorohydrin rubber diaphragm can
work under pressure 0.4 ~ 0.8MPa , air tightness, anti-aging ,
longevity and engine overhaul life equal.
Produce Structure
Tract: Valve’s crust and close over is made of aluminum alloy
that’s formed by pressing die, good appearance, heavy intensity, no
gas leak. Structure of connection of two back pressing air of
interval channel of valve is reasonable. this design make
“ubmerged-type” true due to opening and closing face of valve
locate in air pocket. Air from pocket can come in blowing
cannulation straightly. It accord request with low air pressure and
big quantity of blowing.
Electromagnetically operated valve: Control pulse valve by
remoting. With trube base coil and DIN electrical outlet, conwiniet
inner setting or outer setting, waterproof and dustproof for
protect. Upto JB/t5916-91 standard.
Membrane patch: Adopt dish-type, and big moving. Valve can be
opened in 0.08-0.1 second. You can choice synthetic rubber membrane
patch made of import materials in frigid climate. Membrane patch
can be longest used when working temperature is from -40℃ to -55℃.
