High and Medium Pressure Gas Safety Relief Valve

High & Medium Pressure Safety Relief Valve

The safety relief valve serves as the optimal overpressure protection device for pressure-bearing equipment, vessels and pipelines. When the medium pressure rises above the allowable value, the safety valve opens automatically and then performs full-volume discharge to prevent further pressure build-up. When the pressure drops to the preset value, the safety valve closes automatically in a timely manner.

For the low-lift type, the outlet bore is equal to the nominal diameter; for the full-lift type, the outlet bore is one size or more larger than the nominal bore.

Connection Type: Flanged Connection

Nominal Diameter:

DN20–DN300 (for nominal pressure 16–40 Bar)

DN20–DN150 (for nominal pressure 64–100 Bar)

DN15–DN50 (for nominal pressure 160–320 Bar)

High & Medium Pressure Low-lift Safety Relief Valve

Connection Type: External Thread Connection

Nominal Diameter: DN15–DN25

Nominal Pressure: 16–160 Bar

High & Medium Pressure Pilot Operated Safety Relief Valve

The pilot operated safety relief valve is a safety valve with a new structure. It changes the direct action of the spring into indirect action via a pilot valve, featuring high responsiveness, high operating accuracy, good repeatability, long service life and stable and reliable performance. This product can be calibrated on-site. After repeated popping and discharging, it can still automatically re-seat with tight shutoff, and is easy to operate and maintain.

Connection Type: Flanged Connection

Nominal Diameter: DN25–DN200

Nominal Pressure: 16–100 Bar
