Cast Iron DIN Duo Check Valve PN16

DIN duo check (double-door) non-return valve engineered to prevent backflow and reduce the risk of water hammer in piping systems. The dual-plate design enables fast closing with short travel, delivering stable one-way flow control with low pressure loss compared to many traditional check valve designs. Cast iron body provides a durable, cost-effective solution for general utility duties such as water and other non-aggressive media. NBR seat supports reliable sealing and consistent shut-off performance. Designed for PN16 installations in pump discharge lines, distribution networks, and industrial utility circuits where compact backflow protection is essential.
