Vapour Control

Good corrsion resistance,chemical resistance,resistance to adhesion of liquid and vapor,resistance to extreme temperature

Fully open at 10% overpressure

The leakage is much smaller than API2000 standard and ensures a higher setting accuracy(±3%)

Supports ANSI, HG/T flanges

The valve trim assembly can be replaced on site

Genuine zero leakage is achieved before the valve opens.

All components are field-replaceable.

The valve reaches the full lift height the instant it opens.

Suitable for corrosive operating conditions.

The buckling pin remains within the elastic deformation range prior to instability, rendering it less susceptible to fatigue.

Compatible with flanges conforming to ANSI, DIN and HG/T20592 - 20635-2009 standards.

Specifically designed  for tank filling

Operates effectively at supply pressures from 10PSIG to 200PSIG

Equipped with standard NPT inlet and outlet

Pressure balanced valve

Optional ANSI 150 lb or 300 lb flange connections

Optional supply line filter available

Self-actuated design automatically opens to allow filling gas flow

Set point is unaffected by supply pressure

Automatically closes when tank pressure returns to the set pressure

Various orifice sizes are available, allowing for flow rate adjustment tailored to the size of the storage tank

Nitrogen supply pressure: 0.2- 0.8MPa

After valve: 0.5-100KPa

Sensitive response, high precision gas control

Connection mode : flange, thread

Pilot type structure, stable operation

Allowable leakage level
