The Flat Gate Valve is a type of valve that is primarily used for on/off service in various industrial applications. This valve features a flat gate design, which allows for a smooth flow path when fully opened, minimizing turbulence and pressure loss. The flat gate valve is known for its simple design, reliability, and ease of operation, making it a popular choice in water supply, wastewater management, and other fluid control systems.
The two sealing faces of a flat vgate valve are perpendicular to the pipeline axis, its closing member is a single disc, valve equipped with a stretching mechanism. 
From the aspect of structure style, the through conduit gate valve can be divided into two types of valves with diversion holes and valves without any diversion hole.

Features:

• Efficient Flow Control: The flat gate design provides a straight-through flow path, reducing resistance and allowing for efficient fluid movement.
• Simple Construction: With fewer moving parts than other valve types, the flat gate valve is easy to operate and maintain.
• Robust and Durable: Typically constructed from high-strength materials such as cast iron, carbon steel, or stainless steel, these valves are designed to withstand harsh operating conditions.
• Versatile Applications: Suitable for a wide range of fluids, including water, oil, and gas, making them adaptable for various industries.
• Low Maintenance: The design minimizes wear and tear, leading to lower maintenance requirements and extended service life.

• The valve disc and valve seat seal are repeatedly treated by special processes, and protected by multiple seals, and featured with anti-corrosion, penetration-proof, anti-abrasion and long service life;
• Valve seat is designed with hard-soft double seal, having reliable tightness;
• With a full bore design, both the coefficient of flow resistance and the pressure loss are very small;
• When the valve is fully opened, medium erosion occurring to its sealing face is smaller than that of other valves;
• The through conduit gate valve with diversion holes installed on a pipeline can also be cleaned by a pipe cleaner directly;
• For adjustment structure, the valve have a good flow adjusting ability;
• No space restriction on valve installation, that is, both parallel and perpendicular installations are allowed.
