Electric temperature control valve sleeve using cylindrical thin window shaped valve guide. With DKZ straight travel electric actuator, receiving 0 ~ 10 or 4 ~ 20mA.DC signal driving the valve opening and closing. The high temperature electric control valve sleeve for the two fluid mixture into third kinds of fluid, or different temperature of the same fluid, mixed into the same temperature of fluid. Three way valve to a fluid into two fluid.
Electric temperature control valve sleeve diameter from 25mm to 200mm, the nominal pressure of 1, 1.6, 4, 6.4MPa, temperature range of -60 ℃ to 450 ℃, the control signal is 0 ~ 10 or 4 ~ 20mA.DC. With different actuators can be divided into common type and the electronic type two.
