Gate valve for pipelines: Installed at the end of drainage pipelines, a check valve with the function of preventing backflow of external water. The gate valve is mainly composed of four parts: valve seat, valve plate, water sealing ring, and hinge. The shapes are divided into round and square. Traditionally made of various metal products, the material of the gate valve has now evolved into various composite materials.

The butterfly valves offer several advantages over traditional gates: 1. Greater energy efficiency (such as doors that open and close without the need for manual force) 2. Longer service life (simple mechanical structure, easy maintenance) 3. Easy to use (no manual operation required)

Operating Principle

The gate is composed of four parts: valve seat (body), valve plate, seal ring, and hinge. It is used exclusively for circular and square outlets of unidirectional water flow. The structure is tight, operation is reliable, and no manual operation is required; the closing force comes from the water pressure source. When the water pressure inside the gate exceeds the pressure outside, it opens; conversely, it closes. Suitable medium: water, river water, lake water, seawater, domestic, and industrial wastewater. Application range: suitable for hydraulic systems, municipal wastewater treatment, urban flood prevention and drainage, sewage treatment plants, waterworks, etc.
