可调整的压力减少/维持阀Di

Diaphragm type adjusting pressure reducing/sustaining valve is installed in feeding/draining water system in high building to reduce the inlet pressure to required pressure. The valve ensure outlet pressure stay in the setting value stably on its own energy, namely the outlet pressure does not change owing to the inlet pressure and flow change. There is a self- cleaning filtering mesh installed at the valve control system's inlet to prevent the great specific gravity and large diameter particle flow in to the system and ensure the system is unimpeded. The valve acts quickly and has a long life.
