Feature

ZZYP self-operated pressure regulator adopts the external pressure extraction structure, which can automatically adjust and stabilize pressure depending on the pressure change of the medium itself. It has the characteristics of simple structure and reliable movement.Using balanced bellows valve core structure, has the unbalanced force is small, nimble, widely used in all kinds of low viscosity liquid, gas and steam, is a kind of applied in the use of energy-saving products without gas and electricity;

ZZVP self-reliance declined pressure regulating valve with external pressure and internal pressure of two kinds of structure, can rely on the media’s own pressure changes to achieve the purpose of automatic adjustment and stable pressure, has the characteristics of simple structure, reliable action;Suitable for various non-corrosive gas pressure relief or pressure relief stable occasions;

ZZCP self-reliance type differential pressure regulating valve outside using pressure structure, can rely on the media itself before and after the valve to automatically adjust the pressure change and stability of the pressure difference, the purpose of has the characteristics of simple structure, reliable action;Applicable to all kinds of differential pressure regulating the corrosive gas and low viscosity liquid.

ZZYPII operational command device self-reliance type pressure regulating valve by valve (the main valve), actuators, command device of three parts, can rely on the pressure change of modulated medium itself to achieve the purpose of automatic adjustment and stable pressure, applicable Yu Dake than, decompression of the large pressure difference voltage or pressure regulator.

ZZDG type nitrogen seal regulating valve has two kinds of nitrogen supply regulation and nitrogen release regulation, which can depend on the pressure change of the regulated medium itself to achieve the purpose of automatic regulation and stable pressure.Is mainly used to keep the container at the top of the shielding gas (usually nitrogen) pressure constant, so as to avoid direct contact with the air container material, prevent evaporation materials, oxidation, and the safety of the vessel;This series of nitrogen sealing device is especially suitable for the gas seal protection system of all kinds of large storage tanks.It can be divided into two types: nitrogen relief type (K type) and nitrogen supply type (B type).

The series of regulating valves are divided into two types: control valve front (type K) and control valve back (type B).

Key feature

  • The regulator is with commander control,it has high control accuracy,and control easily
  • Excellent dynamic control performance and static shut-off ability.it can widely used in all kinds of micro-pressure N2 seal system and gas regulator supply system.
  • The lever’s force control makes the control accuracy and stable,and the work only need 0.03Mpa inlet pressure
  • The regulator is equipped with output pressure gauge,it makes the installation very easy on site.
