This product is a GB Casting concealed stem soft seal gate valve designed for on-off service in pipeline systems, particularly suitable for water and neutral fluid transmission lines. The valve features an elastically sealed gate fully encapsulated with rubber, which ensures tight contact with the valve seat through elastic deformation, achieving reliable bubble-tight shutoff when closed. The non-rising stem design keeps the stem from extending outward during operation, resulting in a compact structure and reduced installation space requirements, making it ideal for underground pipelines, valve chambers, and confined installation areas. The body is made of ductile iron, providing good strength, toughness, and pressure resistance for PN16 service conditions. With low operating torque and smooth actuation, the full-bore flow passage minimizes flow resistance when fully open, maintaining system efficiency. This valve is widely used in municipal water supply and drainage networks, fire protection systems, HVAC installations, and general industrial water engineering, serving as a standard shutoff valve in pipeline infrastructure.
