● Overview
ZAZQ, ZAZX electric three confluence, shunt valve using a window-shaped thin-walled cylindrical spool oriented. With straight trip DKZ type electric actuator to accept 0-10 or 4 ~ 20mA.DC signals drive the valve open and close. Wherein the temperature of the fluid in the same three-way mixing valve for mixing two fluids into the third fluid or fluids with different temperatures, a mixed. The three-way diverter valve to a fluid into two streams.
This series of products from the nominal diameter 25mm to 300mm, nominal pressure has 1.6,4.0,6.4 MPa, the applicable fluid temperature from -60 ℃ to 450 ℃, the control signal is 0 to 10 or 4 ~ 20mA.DC, leakage standards Ⅳ ⅵ grade level or flow characteristics are linear, parabolic two kinds. Equipped with different valve cover can be divided into common type and heat two.
