    Product Details
    Specification (1)
    🛡️

    Safety Relief Valve had wide Application of water, air gases, steam, any other gases and liquid. Internal set value adjuster is connected to the set pressure spring and guided to the plug which lifts when the inlet pressure exceeds preset set value adjuster limits.

    ⚙️

    A Safety Relief Valve is a critical protective device designed to safeguard boilers, pressure vessels, and other pressurized systems from overpressure conditions. When the pressure in a system exceeds the preset allowable limit, the valve automatically opens to release excess fluid or gas, preventing potential equipment damage or safety hazards.

    💧

    These valves are widely used across applications involving water, steam, air, gases, and various liquids. The valve operation is governed by an internal spring mechanism connected to a set pressure adjuster, which controls the lifting of the valve plug when the system pressure surpasses the predetermined limit.

    Frequently Asked Questions
    ❓ What is a Safety Relief Valve used for?
    A Safety Relief Valve is a protective device used to safeguard boilers, pressure vessels, and pressurized systems from overpressure conditions. It automatically opens to release excess fluid or gas when system pressure exceeds the preset limit, preventing equipment damage and safety hazards.
    ❓ What media are Safety Relief Valves compatible with?
    Safety Relief Valves are compatible with a wide range of media, including water, steam, air, various gases, and liquids. This makes them suitable for diverse industrial and commercial applications.
    ❓ How does the internal spring mechanism work?
    The valve operates through an internal spring mechanism connected to a set pressure adjuster. When the system pressure surpasses the predetermined limit, the spring-controlled plug lifts, allowing excess pressure to be relieved safely.
    ❓ What materials are used in the construction of this Safety Relief Valve?
    Key components are made from high-quality materials including Ductile Iron QT450 (valve body, disc, cover, diaphragm pressure plate), Copper (valve seat, ball valve, pilot valve, needle valve, pipe), Reinforced Nylon Rubber (diaphragm), Spring Steel (spring), and SS201 Stainless Steel (bolts).
    ❓ What pipe sizes (DN) are available for this valve?
    The Safety Relief Valve is available in the following sizes: DN50, DN65, DN80, DN100, DN150, DN200, and DN250, with corresponding face-to-face dimensions (L) ranging from 240 mm to 550 mm.
    ❓ How can I obtain specifications, drawings, or a quotation?
