4A Globe Valve – Class 150 to 2500, Sizes ½" to 24" - NSW

The NSW 4A Globe Valve is engineered for high-integrity flow control across a broad range of industrial processes. Featuring a plug-shaped valve disc and linear motion for effective throttling and shut-off, this valve is ideal for regulating the flow of steam, air, corrosive fluids, or slurries. Available in pressure ratings from Class 150 to 2500 and sizes from NPS ½ to 24 (DN15 to DN600), this valve is constructed from duplex stainless steel A995 4A and other high-grade alloys such as Monel, Inconel, Hastelloy, and WCB. The design ensures a blow-out-proof stem, pressure balancing features, and optional locking mechanism. Conforming to API 600 and tested per API 598, it ensures safe, reliable operation in harsh environments including oil & gas, petrochemical, marine, and power generation sectors.
