Swagelok SS-CHS8MM-1 is a 316 stainless steel poppet check valve designed to control backflow in general-purpose and high-purity applications. This CH series valve provides reliable performance with a fixed cracking pressure of 1 psig (0.07 bar) and is rated for high-pressure service up to 6000 psig (413 bar) at ambient temperature.

Equipped with 8 mm Swagelok tube fitting connections at both the inlet and outlet, this valve ensures leak-tight performance in critical fluid systems. The poppet design offers a maximum flow coefficient (Cv) of 1.8, making it suitable for a wide range of industrial processes requiring precise directional flow control.
