Open Die Forged Globe Valve

NSV Open Die Forged Globe Valve

The NSV open die forged globe valve is manufactured using solid open die forging, resulting in a dense, defect-free structure that significantly enhances pressure resistance and service life.

We offer open die forged valves in both carbon steel and stainless steel, tailored to diverse media and operating conditions. Suitable for high-temperature, high-pressure steam, water, oil, as well as corrosive or clean fluid services.

Available with handwheel or gear operator for smooth and reliable operation, widely used in power generation, petrochemicals, LNG, pharmaceuticals, and other critical industrial applications.
