Composite exhaust valve quick exhaust 2-4 inch flange

1.AdIntegrated dual function design, efficient and cost saving

Integrating the two major systems of high-speed massive exhaust and continuous micro exhaust, one equipment replaces two traditional valves, greatly reduces the cost of procurement and installation, and saves pipeline space. At the same time, it can quickly empty the air in the pipeline and reduce the air resistance, which not only improves the efficiency of water filling and water delivery, but also reduces the energy consumption of the water pump to achieve stable operation under all working conditions.

2.Intelligent negative pressure protection to ensure system safety

When the pipeline stops pumping or has a sudden negative pressure, it automatically and quickly enters the air to effectively prevent the pipeline from being deflated and deformed by negative pressure, while restraining the phenomenon of water hammer, avoiding damage to equipment and pipelines, prolonging the service life of the system and reducing the maintenance cost in the later period.

3.High durability and low maintenance, suitable for complex working conditions

It adopts ductile iron valve body and stainless steel floating ball, which has strong compression resistance and corrosion resistance, and is suitable for a variety of industrial media and harsh environment. The soft and hard composite seal realizes zero leakage in the whole pressure section, and supports online maintenance, without emptying the pipeline, shortens the maintenance time, and reduces the consumption of manpower and materials
