Safety Valve – China Manufacturer & Supplier

Premium Quality Safety Valves from China

As a professional China safety valve manufacturer, Yuanjd Valve specializes in the design, production, and supply of high-performance safety valves for critical overpressure protection applications. Our safety valves are engineered to serve as the “last line of defense” for industrial systems—automatically releasing excess pressure from vessels, boilers, and pipelines to prevent catastrophic equipment failure, environmental hazards, and life-threatening accidents.

A safety valve is an automatic pressure-relieving device that opens with a rapid “pop” action when system pressure reaches the set point, discharging compressible fluids (steam, gas, air, or vapor) to a safe location. Unlike relief valves which open gradually for liquid service, safety valves are designed for compressible media and provide full lift instantaneously at the set pressure. This rapid full-opening characteristic—accompanied by the distinctive popping sound—ensures immediate pressure reduction, protecting boilers, pressure vessels, steam drums, and gas systems from dangerous overpressure conditions.

Manufactured in strict accordance with ASME Boiler and Pressure Vessel Code Section VIII and API 526—the leading international standards for safety and pressure relief valves—our safety valves are available in sizes from NPS 1/2″ to 12″ (DN15 to DN300) with pressure ratings from Class 150 to Class 2500 (PN20 to PN420) and temperature ranges from -196°C to +538°C.

Safety Valve Types & Technical Specifications

We offer three primary safety valve types to suit different system requirements:

• Spring-Loaded Safety Valve – The most common type, utilizing a spring mechanism to maintain set pressure. When system pressure exceeds the spring force, the disc lifts to release pressure. Available in conventional and balanced bellows designs.

• Pilot-Operated Safety Valve – Uses an auxiliary pilot valve to control the main valve, providing precise control in high-pressure and large-capacity applications.

• Balanced Bellows Safety Valve – Incorporates a bellows element to minimize the effects of backpressure on operational characteristics, ensuring accurate and reliable operation even in variable backpressure conditions.

Key Specifications:

• Design Standards: ASME Section VIII, API 526, API 520, API 527

• Testing Standards: API 527, ISO 4126-1, ASME PTC 25

• Size Range: NPS 1/2″ to 12″ (DN15 to DN300)

• Pressure Rating: Class 150 to Class 2500 (PN20 to PN420)

• Temperature Range: -196°C to +538°C

• Body Materials: Carbon steel (A216 WCB/WCC), stainless steel (CF8/CF8M), alloy steel

• Connection Types: Flanged (ASME B16.5), threaded (NPT/BSP), butt-welding

Applications & Industries

Safety valves are the critical safety backbone across multiple industrial sectors:

• Oil & Gas – The largest segment of the safety valve market, protecting pipelines, refineries, wellheads, and compressor stations from overpressure

• Power Generation – Boiler steam drums, superheaters, reheaters, and economizers

• Chemical & Petrochemical – Pressure vessels, reactors, and process systems handling hazardous media

• Pharmaceutical & Food Processing – Sterile and sanitary overpressure protection

• Water & Wastewater Treatment – Pump discharge and pipeline systems

• Pulp & Paper – Process equipment protection
