ZAZQ,ZAZX Confluence Shunt Temperature Regulating Valve product description
ZAZQ,ZAZX Confluence Shunt Temperature Regulating ValveFeatures
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.
