Safety Valve FSV-3F – The YNV FSV-3F is a high-performance full bore safety relief valve engineered by YNV Valve (Korea) to provide dependable overpressure protection across steam, compressed air, liquid, and oil applications. Designed to automatically open and discharge excess pressure when system pressure exceeds preset limits, the FSV-3F helps protect pressure vessels, boilers, piping systems, and industrial equipment from dangerous overpressure conditions
Manufactured with a cast steel body and stainless steel trim, this valve delivers excellent durability and corrosion resistance even in demanding industrial environments. It is available in both lever-operated and non-lever configurations with JIS or ANSI flanged connections for flexible installation. The FSV-3F supports wide operating conditions with high working pressures up to approximately 22–33 kgf/cm² (≈22–33 bar) and temperatures up to 250 °C, making it suitable for heavy-duty service.
YNV’s safety valve design incorporates tight sealing and reliable performance to ensure safety and stability in critical systems. With sizes ranging from DN15 to DN100 (½″ to 4″), the FSV-3F is an ideal choice for industrial steam, air, and fluid pressure protection
