    The 3-Inch 303 SS BSSV Style Vacuum Breaker Threaded In-Line Check Valve is a reliable solution for protecting pressure vessels, tanks, and piping systems from damage. With a cracking pressure of 0.15 psi, this valve prevents condensate backup and pipe collapse during transient pressure drops. Its stainless steel construction ensures durability, and the spring-assisted silent closing mechanism allows for tight shut-off to prevent water hammer. Suitable for various applications such as antisiphon, boiler feed, and steam systems, this valve offers versatility and ease of maintenance. Meeting ANSI and MSS standards, it is a dependable choice for institutional and government procurement needs.
