Description
1. Overview of Soft Sealing Gate Valve
The soft sealing gate valve, also known as the cast iron elastic seat sealing gate valve, features a cast iron body and a gate plate fully encapsulated with high-quality rubber. The rubber’s elasticity and deformation ensure a secure seal, achieving zero leakage. These valves are widely used in water supply, sewage systems, and industrial pipelines.

3. Product Features
- Flat-bottom design: Eliminates grooves in the valve cavity, preventing debris accumulation and ensuring smooth fluid flow.
- Rubber encapsulation: The gate plate is fully covered with high-quality rubber, ensuring durability, precise dimensions, and excellent elastic memory.
- Corrosion resistance: Components like the valve stem, stem nut, and sealing sleeve are made of corrosion-resistant materials such as stainless steel and copper. The valve body is coated with epoxy resin, meeting standards for potable water.
- Reliable sealing: Equipped with three “O-ring” seals for effortless operation and long-lasting, maintenance-free performance.
- Pressure-sealed O-ring replacement: Allows for easy replacement of the O-ring without shutting off water supply.
- Embedded brass nut: The brass nut is securely embedded into the gate plate, preventing loosening or detachment.
- Precision casting: The valve body is precision-cast to ensure internal sealing without additional machining.
