Safety Valve

Bellows Balanced Safety Valve

This valve is applicable to equipment and pipelines with unstable back pressure, toxic or corrosive media at working temperature ≤ 200°C, and serves as an overpressure protection device. For connecting flange standards: adopt JB/T……-94 Series 1 when PN ≤ 4MPa; adopt JB/T……-94 Series 2 when PN ＞ 4MPa.

Full Lift Safety Valve with Lifting Wrench

Full Lift Safety Valve with Lifting Wrench for steam/air (≤350℃) and air/petroleum gas (≤300℃) systems. Complies with JB/T-94 standards for pressure protection with proper flange connections.

Low Lift Enclosed Bonnet Safety Valve

Type A41H safety valve for petroleum gas, air, water (≤300°C). Type A41Y-P/R for corrosive media (≤200°C). Overpressure protection with JB/T flange compliance.

Pilot Operated Safety Valve

Pilot Operated Safety Relief Valve features innovative indirect pilot actuation for superior sensitivity. With sleeve piston design and double-seated sealing, it offers high accuracy, zero leakage, rapid re-seating, and handles high back pressure. Supports online calibration, automatic tight shutoff after discharge, and easy operation—ideal for petroleum, chemical, power, and gas industries.
