NSV Pneumatic Forged Steel Ball Valve

Ball valves offer rapid opening/closing, reliable sealing, and minimal flow resistance, making them ideal for frequent operation and high-purity or corrosive services. This pneumatic ball valve is constructed from forged super austenitic stainless steel 904L (UNS N08904), a high-alloy material with exceptional resistance to sulfuric acid, phosphoric acid, chlorides, and seawater due to its elevated levels of chromium, nickel, molybdenum, and copper.

Designed as a floating ball type with soft seat sealing, it ensures tight shut-off with low operating torque. Pneumatic actuation enables fast, remote on/off control in critical chemical and high-pressure process applications.
