47-21100 pneumatic single-seat control valve

47/48-21000 series pneumatic single-seat adjusting valve, made up of ∑F actuator and 21000 series single-seat valve. ∑F actuator made up of general spring diaphragm actuator and power amplification system, use lever enlarge principle. Make the output force of actuator larger 2.6~5.2 times, 21000 series single-seat valve use top-guide structure, ensure stable operation of valve spool. Almost suitable for controlling all kinds of fluids

Main features:

1、 contain all kinds of valve spools, quick switch of valve spool, low capacity of valve spool, soft sealing of valve spool, low noise and anti-corrosive valve spool, widely used

2、 use top-guide structure, large guide area, good stability

3、 small leakage

4、 equipped with ∑F actuator, can receive high pressure difference

5、 sealing surface of valve spool, valve seat use cobalt chromium tungsten carbide hard alloy, improved using life
