Double Door Wafer Check Valve -PN 16
The BLAZE™ BT 1411 Double Door Wafer Check Valve is a robust and compact non-return valve designed for use in HVAC, plumbing, and industrial water systems. With its space-saving wafer-style body and dual spring-loaded discs, the valve ensures silent and efficient prevention of backflow. Engineered in accordance with BS EN 12334, the valve supports installation between BS EN 1092-2 PN 16 flanges, making it suitable for a wide range of system layouts. WRAS approval for sizes 2″ to 12″ ensures compatibility with potable water systems, while larger sizes up to 36″ are built to the same high standards for industrial use. The valve features epoxy-coated ductile iron components, a WRAS-approved EPDM seat, and a stainless-steel spring, offering durability, chemical resistance, and long operational life across a wide temperature range.
