Versatile Connection and ConstructionOur pressure safety valves are compatible with both BSP and NPT threaded end standards, allowing for seamless integration into new or existing piping systems. The body is available in various finishes, including natural brass, nickel-plated, and powder-coated options, ensuring suitability for harsh industrial environments. Sturdy disc and handle materials-primarily stainless steel-further guarantee long-term durability and resistance to corrosion.
Safety and Performance AssuredEach safety valve is rigorously tested to 1.5 times its maximum working pressure, adhering strictly to IS, API, and BS standards. The direct acting, spring-loaded design enables rapid response to overpressure, while blowdown and back pressure limitations maintain system stability. PTFE or metal sealing provides leak-tight performance even in demanding applications, supporting a wide operating temperature range.
FAQ's of Screw End Pressure Safety Valve:
Q: How does the Screw End Pressure Safety Valve provide overpressure protection?
A: This valve is a spring-loaded, direct acting safety device that automatically opens when system pressure exceeds its set limit (1 to 20 kg/cm2), relieving excess pressure to maintain optimal and secure operation in industrial, chemical, and utility systems.
Q: What are the available end connection standards and how do I select the right one?
A: The valve offers BSP and NPT threaded (screwed end) connection options, making it compatible with diverse piping systems. Choose BSP for British-standard piping or NPT for American-standard taps, based on your existing system design and installation region.
Q: Where can I install these pressure safety valves, and what positions are allowed?
A: The valves are suitable for vertical or horizontal mounting and can be installed in steam, water, oil, gas, or chemical pipelines in industrial environments. Ensure the orientation supports proper operation and maintenance access.
Q: What is the recommended process for installing and testing the valve?
A: Ensure the pipe is depressurized before installation. Fit the valve into the threaded port, using the correct sealant and torque. Post-installation, pressure-test the assembly to 1.5 times its working limit as per IS/API/BS standards to confirm reliable sealing and operation.
Q: How do features like corrosion resistance and easy maintenance benefit my operation?
A: With materials like brass, stainless steel, or gunmetal and special coatings such as nickel plating, the valves resist corrosion and ensure long service life. The simple structure and direct acting design facilitate easy inspection, cleaning, and maintenance, minimizing downtime.
Q: What media and temperature ranges can the valve handle, and for what applications is it best suited?
A: Suitable for air, water, steam, oil, and various gases, the valve operates efficiently between -10C and 220C. It is ideal for industrial, chemical, oil & gas, water supply, and steam distribution applications requiring reliable overpressure protection.
