VCR External thread straight-through ball valve

The VCR straight-through ball valve is a quarter-turn, quick-acting valve designed for ultra-high-purity piping systems in the semiconductor, hydrogen energy, and photovoltaic industries. Its body is machined from a single piece of 316L-VAR high-purity stainless steel bar stock and features integrated VCR male end connections; it utilizes a metal gasket to achieve an all-metal seal, eliminating the risk of contamination associated with rubber O-rings. Unlike VCR needle valves, which require slow, multi-turn adjustments, this ball valve transitions between fully open and fully closed with a simple 90-degree turn of the handle. Its straight-through, high-Cv flow path ensures minimal pressure drop, making it ideal for the rapid isolation and switching of high-purity gas lines, though it is not suitable for precision flow throttling. VCR nuts and metal gaskets are complementary consumables that must be selected separately; the valve is widely used in specialty gas cabinets, VMB panels, and vacuum process piping systems.
