Water seal globe valve
The Water Seal Globe Valve is designed for high-pressure steam, gas, and liquid pipelines where tight sealing is critical. Its water seal structure prevents leakage and backflow, ensuring operational safety. Constructed with stainless steel, carbon steel, or alloy materials, the valve offers durability, corrosion resistance, and long-term reliability.
Water seal globe valve
The Water Seal Globe Valve is engineered for applications requiring absolute sealing and flow control, commonly used in boilers, steam lines, chemical pipelines, and energy systems. Its water-sealed design prevents leakage and enhances operational safety.
Available in manual, bevel gear, or electric operation, the valve can be customized for various sizes, pressure ratings, materials, and connection types. Its robust construction withstands high pressure, temperature fluctuations, and corrosive media, ensuring long service life.
Water Seal Globe Valves are manufactured and tested according to international standards:
