pneumatic operated single-seat control valve

regulator vlalve of top oriented structure  compact Structure, S-Fluid channels ;
 low lossing reduction voltage ; big flowing ;big adjustable scope ;high precision of low characteristic

curve; complies with the standards IEC534-1976  big area Valve core Avoid vibrations ability is perfect

the standard of valve seat leaking rate Complies with the standards ANSIB16.104

regulator use Spring type film actuators, so it has compact structure and large outputing .it can used

for the liquid flows for differnt  pressure and temperature
