Double door wafer check valve is a flanged resilient swing check valve designed to prevent reverse flow of fluid in pipelines. The valve has an elastic sealing ring to ensure excellent sealing performance, and the swing valve disc can automatically close when the fluid pressure changes, effectively preventing backflow.
This double door wafer check valve is designed to effectively prevent media backflow in pipeline systems. It features a compact wafer structure with dual plate design, quick opening and closing, small flow resistance, and stable performance. It is widely used in water supply, drainage, fire protection, HVAC and industrial pipelines.
