Electric Control Valve Electric Control Valve with Big Diameter
Summary
This series is suitable to the regulation which requests high precision, during the flux of control liquid.
Electric single-seated, double-seated and sleeve regulating valves are composed of common DKZ series or imported electric actuator series and valve body which valve core is single-seated type, double-seated type or sleeve type
It has a lot of control way, flow characteristic equal percentage and linearity
Parameters of Automatic Control Valve
The material of valve body: cast iron, cast steel, cast stainless steel and so on.
Pressure grade: 1.6Mpa, 4.0Mpa, 6.4Mpa
Connecting type: flange coupling
Temperature range: normal temperature -20---230ºС the thermal slug type -60---450ºС
Operation form: automatic open or close
Flow characteristic: equal percentage, linearity
Leakage: single-base valve: 0.01* rating Kv
double-base valve, sleeve valve: 0.5%* rating Kv
