    Description

    ZZYM Sleeve type self-operated Control valve


    • ZZYM SLEEVE TYPE SELF-OPERATED REGULATOR FEATURE

      ZZYM Sleeve type self-operated regulator is sleeve seat structure, which can adjust the pressure as the set value with it’s medium own energy and without any outer energy.The most advantages of ZZYM Sleeve type self-operated regulator is that it can be suitable for the working place of no power and no pneumatic equipment available, additional,ZZYM Sleeve type self-operated regulator can save energy for the end-user, and the pressure is adjustable within the set range.

      Self-operated regulator has the following types according to the different working conditions:

      ZZYP(single-seat type), ZZYM(sleeve type) and ZZYN(double-seat type), and ZZYM Sleeve type self-operated regulator also has three different covers such as common one, long-neck one and cooling type. For different applications, ZZYM Sleeve type self-operated regulator has three different types of actuators:film/piston/bellows.

      ZZYM Sleeve type self-operated regulator has other advantages as smart and accurate regulating,taking up small space and simple operation and it’s widely used in the pressure control of gas,steam or water in petroleum, chemical, electric power, metallurgy, food, textile, machinery, civil construction industry.

      ZZYM Sleeve type self-operated regulator is designed and manufactured according to the standard of AMSE/API/BS/DIN/GB

    • ZZYM SLEEVE TYPE SELF-OPERATED REGULATOR PRESSURE ADJUSTING RANGE


      Note:1. ZZYM Sleeve type self-operated regulator take diaphragm type actuator for example. If the pressure of ZZYM Sleeve type self-operated regulator is 1000～3000KPa, please consult our customer service or sales people.
      2.The table above is Pressure Subsection Range. Choose the median around for pressure control. The smaller the pressure range, the higher the precision . Therefore it should be used within the pressure setting range.
      3. If the pressure ratio between before valve and after valve of ZZYM Sleeve type self-operated regulator with the pressure control after valve exceeds 10,it needs multi-stage decompression or two ZZYM Sleeve type self-operated regulator in series (can choose control valve with director except pressure before valve is below 0.8MPa)
      4.It needs special design when the nominal pressure is over 6.3MPa.
      5.This series ZZYM Sleeve type self-operated regulator’s lowest pressure control is 15 KPa.
