Pilot Operated Safety Valve
Pilot Operated Safety Relief Valve is a safety valve with innovative structure designed for optimal overpressure protection in various industrial applications.
Applications
Widely used in petroleum and natural gas, chemical, power, metallurgy, city gas and other industries, serving as the optimal overpressure protection device for pressure-bearing equipment, vessels and pipelines.
Key Advantages
- Indirect actuation via pilot valve instead of direct spring actuation for improved operational sensitivity
- Main valve adopts sleeve piston type with double-seated sealing structure
- High operating accuracy and excellent repeatability
- Rapid re-seating with zero leakage capability
- Capable of discharging under high back pressure conditions
- Long service life with stable and reliable performance
Operational Benefits
Supports on-line calibration and automatically re-seats with tight shutoff after repeated popping and discharging. Designed for easy operation and maintenance.
