Designed for Process Industries, S70/S90 Valves Excel in High-Temp and Vacuum Applications
Series 70/90 Threaded Ball Valves offer an economical solution with a zero-leakage seal in high-pressure and high temperature operating conditions up to 2000 psi (137.9 bar) and high 450° F (232° C), and vacuum Service to 29 inches Hg. (gauge), making them an excellent choice for a wide range of industrial applications in the process industries. Threaded closures on Series 70/90 are manufactured to tight tolerances, ensuring a tight seal.
Series 70/90 threaded, two-piece ball valves feature a standard port design with a hard chromium-plated ball and RTFE seats for low operating torque and extended service life. The bottom entry, blowout proof stems is ASTM A479 Type 316 stainless-steel. Series 70/90 valves also feature an adjustable packing gland for secure sealing, stainless steel safety latch handles and body castings marked with foundry heat number for full traceability.
Series 70 two-piece Cast carbon steel bodies are normalized, and black phosphate coated for added corrosion resistance. Series 90 two-piece cast Stainless steel bodies are investment cast and solution annealed for the highest quality and added strength. Series S70/Series S90 valves are designed to comply with MSS-SP 72 and tested to comply with MSS-SP 72.
With Bray’s industry-leading warranty, reputation for reliability, and service after the sale, Bray Series 70/90 threaded, two-piece ball valves offer an exceptional value in a wide variety of commercial and industrial flow control applications.
