DIN 567002/01 Quick Closing Valve
DIN closing valve adopts high-strength cast housing with stable pressure resistance and durable mechanical performance. Its optimized sealing structure ensures zero leakage during full closing and smooth fluid circulation when fully open.
Overview
Application:It is widely used for fluid cut-off control in marine piping, industrial water, oil and gas pipeline systems. It serves as a key isolation valve to safely close and protect downstream pipeline equipment during maintenance and operation.
