Self operated pressure and differential pressure combination valves are mainly used for pressure and differential pressure regulation in process control, and can be used for non corrosive liquids, gases, steam and other media up to 300 ℃. They work according to the principle of priority action and cannot control two parameters simultaneously.Main technical parameters of control valveNominal diameter DN1520253240506580100125150Rated flow coefficient Kvs46.381620325080125160280Noise measurement coefficient Z value0.60.60.60.550.550.50.50.450.40.350.3Nominal pressure (MPa)1.6； fourMaximum operating temperature (℃)Liquid ≤ 140; Gas ≤ 80hard sealIsolation tank ≤ 200Equipped with isolation tank extension ≤ 300Equipped with isolation tank and heat sink ≤ 300Pressure balancing componentbellowsRolling diaphragmFlange StandardANSI JIS DIN GB JB (special can be provided by the user)Valve body materialCast iron; Cast steel; Cast stainless steelValve core materialStainless steel, soft seal with stainless steel embedded rubber ringMaximum work pressureNominal pressure (note the relationship between △ Pmx and working pressure and working temperature)Main technical parameters of the actuator
