Product description
ZAZQ, ZAZX electric three-way joint flow diversion valve with cylindrical thin-walled window-shaped spool-oriented. Equipped
with DKZ straight stroke electric actuator, to accept 0 ~ 10 or 4 ~
20mA.DC signal to drive the valve opening and closing. Among
them, the three-way confluence regulating valve is used for mixing the
two fluids into a third fluid or the same fluid with different
temperatures and mixing them into the same temperature fluid. A three-way diverter divides a fluid into two fluids.
This
series of products from 25mm diameter to 200mm, the nominal pressure of
1.0,1.6,4.0,6.4 MPa, the temperature range -60 ℃ to 450 ℃, the control
signal is 0 ~ 10 or 4 ~ 20mA.DC. Equipped with different implementing agencies can be divided into two types of ordinary and electronic.
Features
1, the direction of the fluid on the role of the spool are in a flow state, so the work of good stability.
2,
In addition to the valve cover bushing at the guide, the spool side and
the valve seat inner surface also has the role of guide, guide the
area, reliable work.
3, the servo amplifier uses deep dynamic negative feedback, can improve the regulation accuracy.
4, electric operator has many forms, applicable to 4 ~ 20mA.DC or 0 ~ 10mA.DC.
5, electronic electric control valve can be directly controlled by the current signal valve opening, without servo amplifier.
6,
save automation investment, and single-seat, two-seater or sleeve valve
compared to form the same system can save a valve to simplify the
system and save investment.
7, the bellows seal on the movement of the valve stem to form a complete seal, blocking fluid leakage.
