ZDLM high temperature sleeve electric control valve is guided by a cylindrical thin-walled window spool. Equipped with DKZ direct-stroke electric actuator, it receives 0-10 or 4-20 mA.DC signal to drive the valve to open and close. The electric high temperature sleeve control valve is used to mix the two fluids into a third fluid, or the same fluid at different temperatures, to mix into the same temperature fluid. A three-way shunt valve divides a fluid into two channels.
The caliber of the electric high temperature sleeve control valve ranges from 25 mm to 200 mm. The nominal pressure is 1.0, 1.6, 4.0, 6.4 MPa. The temperature range is from - 60 C to 450 C. The control signal is 0-10 or 4-20 mA.DC. Different actuators can be divided into two types: common type and electronic type.
