Swagelok SS-43GS6MM is a 40G series stainless steel 1-piece ball valve designed for reliable performance, thermal durability, and leak resistance. This 2-way straight pattern valve is engineered for shutoff service in a variety of instrumentation and process applications, offering a maximum flow coefficient (Cv) of 1.4 and a room temperature pressure rating of 3000 PSIG (206 BAR).

The 40G series represents an advancement over the traditional 40 series, featuring an innovative assembly process and structure that provides higher thermal cycling capabilities and a reduced potential for leaks. One of its key maintenance features is the ability to make packing adjustments while the valve remains inline, ensuring minimal downtime during routine service.
