Model &Name: ΣF81(82)-6000Series Pneumatic High Pressure Single Seat (Sleeve) Control Valves

Characteristics:The new generation high pressure controlvalve is composed of ΣF Actuators and high pressure 

single seat (sleeve) valves, whoseforce amplifying function (2.5-5.2 times) and cage guiding ,multistage 

pressurereducing, low noise, stable plug action, and large allowable pressure differential;bead welding or 

vacuum fusion with hard alloy for plugs and seats tosignificantly improve the pressure differential resistance 

and cavitationresistance, as well as the service life;
