Check Valve for Pipes: An anti-reverse valve installed at the end of drainage pipes to prevent backflow of external water. The gate is mainly composed of four parts: valve seat, valve plate, water seal ring, and hinge. The shapes available are circular and square. Traditionally made of various metal products, the material of the gate has now evolved into various composite materials.

The butterfly valve offers several advantages over traditional gates: 1. Greater energy efficiency (no need for manual force to open/close the door) 2. Longer lifespan (simple mechanical structure, easy maintenance) 3. User-friendly (no manual operation required)

Operating Principle

The gate valve consists of four parts: valve seat (body), valve plate, sealing 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 opening and closing force comes from the water pressure source. The gate opens when the water pressure inside the gate is greater than the pressure outside, and closes otherwise. Applicable Media: water, river water, lake water, seawater, domestic, industrial wastewater. Application Range: suitable for water conservancy systems, municipal wastewater, urban flood control and drainage, wastewater treatment plants, waterworks, etc.
