The characteristics of the pneumatic control valve of pneumatic membrane tee and materials

Pneumatic film tee pneumatic - valve has two kinds of confluence and shunt effect. Valve core structure using cylindrical thin-wall window, and USES the valve core side guide the 3-way valve (pos. No. In some cases can replace two two-way valve and take over a three links and is widely used, often used in heat exchangers of two phase adjustment, can also be used for simple ratio adjustment. Pneumatic film tee shape of valve core type pneumatic - valve adopts the cylinder thin wall window guidance, is different from the plunger valve core guide bushing. With spring actuator, has simple structure, light weight, small volume, convenient tear open outfit. The next know tee pneumatic - valve pneumatic membrane mainly parts material. The valve body, valve by HT200, WCB, ZGlCr18Ni9Ti; Valve core and valve seat are 1 cr18ni9t, department of titanium alloy; Has enhanced ptfe soft seal valve core; Packing with ptfe, flexible graphite, stainless steel bellows; With a rubber asbestos shim plate, stainless steel round gasket; Membrane by A3; Corrugated diaphragm rubber clip, 5860 and 480 d nylon, 66 mesh cloth; Spring is 60 si2mn; The valve stem, push rod 2 cr13, 1 cr18ni9ti; There are two cr bushing.
