    ZZYN内反馈自力式压力调节阀

    ZZYN Internal Feedback Pressure Regulating Valve

    ZZYN内反馈自力式压力调节阀是本公司针对介质粘度大、易结焦的工况而开发、研制的一类自力式压力调节阀,避免了常规自力式压力调节阀不易保温,导压管容易堵塞、影响调节精度的情况。适用于粘度、易结焦介质的泄压稳压的自动控制。该产品具有节能、动作灵敏、运行可靠、操作与维修方便等特点。广泛应用于石油、化工等行业的原油等高粘度介质的泄压稳压的自动控制。


    ZZYN type internal feedback self type Pressure regulator is the company according to the medium viscosity,easy coking conditions and development,research a kind of self type pressure regulator,to avoid the conventional self type pressure regulating valve is not easy to heat preservation,connecting pipe easy blockage,influence control accuracy.Suitable for high viscosity,easy coking medium pressure relief stabilized voltage automatic control.this product has the energy saving,action quick,reliable operation,operation and easy maintenance,etc.Widely used in petroleum,chemical and other industries of crude contour viscosity medium pressure relief stabilized voltage automatic control.
