ZDLM high temperature sleeve electric control valve
Hits：8326 Update time：2017-05-10
ZDLM high temperature sleeve electric control valve with cylindrical thin-walled window-shaped spool-oriented. Equipped with DKZ straight stroke electric actuator, accept 0 ~ 10 or 4 ~ 20mA.DC signal drive valve opening and closing. Wherein the electric high temperature sleeve regulating valve is used for mixing the two fluids into the third fluid or the same kind of fluid at different temperatures and mixing into the same temperature fluid. The three-way shunt valve divides a fluid into two fluids.
The electric high temperature sleeve regulating valve diameter is from 25mm to 200mm, the nominal pressure is 1.0,1.6,4.0,6.4MPa, the temperature range is -60 ℃ to 450 ℃, the control signal is 0 ~ 10 or 4 ~ 20mA.DC. Equipped with different actuators can be divided into two types of ordinary and electronic.
