EPDM Or NBR Coated Flapper Swing Flex Check Valve For Clear And Sewage Water

EPDM Or NBR Coated Flapper Swing Flex Check Valve For Clear And Sewage Water

Description:

Rubber disc 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 made of ductile iron. 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:

· Double flange design, the disc is composed of DI plate, steel bar shaft and nylon reinforced fabric.
·The rubber disc is totally coated with 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.
·Nylon fabric is inserted into the disc for stengthening the disc from cracking and breaking during operations.
·Much shorter stroke to minimize water hammer and water slamming.
·All iron parts are coated in fusion bond epoxy resin inside and outside of the valve.
·Simple design, top entry cover allows for access for cleaning, replacement and maintenance easy.
·Meets BS EN 1074-3 and BS EN 558 F/F dimensions.
