Detailed Description

We occupy the leading position in electrically operated valve industry Summary This series is suitable to the regulation which requests high precision during the flux of control liquid. Electric single-base, dual-base and sleeve regulating valves are composed of ordinary DKZ series or imported electric actuator series and valve body which valve core is single-base type, dual-base type or sleeve type It can accomplish 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---230º the thermal slug type -60---450º 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 ZAZP,BELLAZP single socket automatic control valve specification table Nominal bore mm 20 25 32 40 50 65 80 100 125 150 200 Valve core diameter mm 10 12 15 20 25 32 40 50 65 80 100 125 150 200 Rated flux coefficient Kv 1.2 2 3.2 5 8 12 20 32 50 80 120 200 280 450 Nominal pressure Mpa 1.6 4 6.4 Match DKJ actuator specification DKZ-4100 DKZ-4200 DKZ-4300 DKZ-5400 DKZ-5500 Differential pressure Mpa 6.4 4.0 4.0 4.0 3.5 2.3 2.0 1.42 1.4 0.91 0.55 0.35 0.26 0.17 Match introduced actuator specification A+Z64 Differential pressure Mpa 6.4 6.4 4.0 4.0 3.7 2.5 2.2 1.6 1.5 1.0 0.6 0.4 0.3 0.2 Rated travel mm 10 16 25 40 40 Flux characteristic Equal percentage Beeline Function style Volt on Volt off Temperature range Normal temperature: -20 — +200 degree abstraction of heat: -60 — +450 degree ZAZN,BELLAZN double socket automatic control valve specification (refer to operation manual) ZAZM,BELLAZM bush automatic control valve specification (refer to operation manual)
