Superior Safety in Steam Systems

Engineered for the protection of boilers and steam pipelines, this safety valve provides precise overpressure actuation with a mechanical spring-loaded design. Its ability to handle back pressure and rapid discharge enhances the safety of industrial steam operations. With set pressures ranging from 0.5 to 16 Bar, it accommodates diverse application needs.


Durable Construction and Corrosion Resistance

Built from high-quality materials such as cast iron, carbon steel, and stainless steel, and featuring stainless steel springs and discs, the valve resists corrosion and wear. Its metal-to-metal seat and external rust protection ensure longevity, even in demanding industrial environments up to 220C.


Flexible Installation and Easy Maintenance

The valve supports a variety of sizes (DN15-DN300), port sizes (1/2" to 12"), and connection types, including flanged (PN16, PN25) and screwed BSP/NPT. Designed for vertical mounting, it is easy to service and recalibrate, facilitating routine maintenance and reducing downtime.

FAQ's of Steam Pressure Safety Valve:


Q: How does the Steam Pressure Safety Valve perform under back pressure conditions?

A: The valve is uniquely engineered for stable operation even when back pressures are present, ensuring reliable pressure relief and consistent protection for steam systems without losing efficiency.

Q: What maintenance processes are required for this safety valve?

A: Routine maintenance is straightforward, thanks to its single body and bolted bonnet design. The valve is easy to service and recalibrate, allowing for quick checks and adjustments without complex disassembly.

Q: When should this type of safety valve be used in steam systems?

A: This safety valve is ideal for applications requiring reliable overpressure protection, such as boiler systems, industrial steam pipelines, and general steam distribution, particularly when stable operation with back pressure is necessary.

Q: Where can this valve be installed within a facility?

A: It is designed specifically for vertical mounting on steam lines, boilers, and pipelines. Its versatile fitting options (flanged or screwed) make installation flexible across various steam infrastructure layouts.

Q: What are the benefits of the metal-to-metal seat and stainless steel components?

A: The metal-to-metal seat offers excellent sealing and durability, while stainless steel springs and discs provide high corrosion resistance, supporting long service life and reliable operation in harsh steam and gas environments.

Q: Which connection and port sizes are available for customization?

A: The valve is available with flanged (PN16, PN25) or screwed BSP/NPT end connections, and port sizes ranging from 1/2 inch up to 12 inch, accommodating a wide array of installation requirements.

Q: How is rapid pressure release achieved by this valve?

A: A high discharge coefficient, combined with a precision spring-loaded mechanism, ensures fast and efficient relief of excess pressure, safeguarding equipment and personnel in demanding steam applications.
