The BuTech 20BC9 ball check valve is engineered for one-way flow in medium-pressure tubing systems, ensuring smooth operation up to 20,000 psi. Featuring a 316 stainless steel body and a 17-4PH poppet, it delivers reliable metal-to-metal seating without elastomeric seals—perfect for high-temperature applications. The valve comes with a stainless steel spring to ensure consistent reseating and prevent backflow under pressure. Compact and robust, it seamlessly integrates into instrumentation panels, testing rigs, and fluid systems where durability and tight performance are critical. Ideal for industrial, petrochemical, and research environments demanding dependable flow control.
