Safety valves are critical pressure relief devices installed in industrial vessels, pipelines and equipment. They automatically open when the internal pressure exceeds a preset limit, releasing excess fluid (gas or liquid) to reduce pressure, and close once pressure returns to a safe level. This prevents equipment damage, leaks or explosions caused by overpressure, ensuring operational safety.

Robust structure composed of valve body, valve disc, spring, bonnet and adjusting mechanism. The spring-loaded design ensures precise pressure control, while the corrosion-resistant materials (stainless steel, carbon steel, alloy steel) adapt to high-temperature, high-pressure and corrosive working environments. Compact size allows easy installation in various equipment.
Automatic pressure relief without external power, with high sensitivity and accurate pressure setting. Good sealing performance to prevent fluid leakage during normal operation. Strong pressure-bearing capacity, capable of handling large flow rates during overpressure, and easy to adjust, inspect and maintain.

Powered by a compression spring to keep the valve closed, suitable for most industrial scenarios (petrochemical, power generation) with stable pressure requirements and wide pressure range.
Operated by a lever and weight, offering precise pressure control, ideal for low-pressure, large-volume vessels such as storage tanks and water treatment equipment.
Widely applied in petrochemical, oil & gas, power generation, chemical processing, pharmaceutical, food and beverage industries. Installed in boilers, pressure vessels, pipelines and storage tanks to provide overpressure protection for equipment and production systems.
