- Long Service Life: High-quality materials and precision machining ensure long service life
- Wide Application Range: Suitable for multiple low-pressure media
Low Pressure Gate Valve is a gate valve product specifically designed for low-pressure operating conditions, featuring simple structure, good sealing performance, and light operation. The closing element of the valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The valve can only be fully opened or fully closed, and cannot be used for regulation and throttling. Low Pressure Gate Valves are suitable for pipeline systems with low-pressure media such as water, air, and steam, and are widely used in industries such as urban water supply and drainage, HVAC, water treatment, and light industry. The product features reasonable design, excellent manufacturing, and reliable performance, making it an ideal choice for low-pressure pipeline systems.
