Ductile Iron Swing Flex Check Valve With Nylon Reinforced Fabric Double Flange

Ductile Iron Swing Flex Check Valve With Nylon Reinforced Fabric Double Flange

Swing Flex Check Valve Ductile Iron EPOXY Coated 40 degree incline Nylon Reinforcement Disc​

Description:

A swing check valve is designed to prevent reverse flow automatically. Under system flow conditions, the movement of the fluid forces the disc to the open position allowing 100% un-restricted flow area through the valve. Under reverse flow conditions, the disc automatically returns to the closed position to prevent reverse flow.

   A rubber flapper swing check valve consists of a valve body, a cover, and a flapper that is connected to a hinge. The disc swings away from the valve-seat to allow flow in the forward direction, and returns to valve-seat when upstream flow is stopped, to prevent backflow. It is under ductile iron construction. Ductile iron provides greater strength and toughness than conventional gray iron materials. With ductile iron construction, the body, disc, and disc arm can safely withstand high stresses and shock loads.

Features:

·Simple design, top entry cover allows for access for cleaning, replacement and maintenance easily.

·Nylon fabric is inserted into the disc for stengthening the disc from cracking and breaking during operations.

· Double fl ange design, the disc is composed of DI plate, steel bar shaft and nylon reinforced fabric.
·The rubber disc is totally encapsulated in EPDM rubber for superior sealing and corrosion resistance.

·The unrestricted full flow area combined with smooth streamline contouring allows for passage of large
solids to prevent potential clogging.
·Much shorter stroke to minimize water hammer and water slamming.
·Fusion Bonded Epoxy (FBE) is provided on the interior and exterior of the valve
·Meets BS EN 1074-3 and BS EN 558 F/F dimensions.

General Applications:
