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:
For general water supply, fire fighting,HVAC/ cooling & sewage system.

Material:

Alpine Flow Control (SuZhou) Co.,Ltd with major focus in the water valve design and manufacturing. The Management staff have over 30 years experience in the water valve design and manufacturing, combined with the high-tech electronics manufacturing experience of multi-national listed companies. This unique combination of traditional and high-tech industry management experience and skills have given us an advantage over the traditional valve manufacturer. More than 40% of our staff are technical staff with knowledge and experience in valve and mechanical design/manufacturing...

Proven and supported by on-going quality and reliability test. AFC has built it’s own in house reliability test laboratory to ensure that our products not only meet the international quality and reliability test specification such as the EN-1074-1/2 T-key and R-key test, but also comply to various international valves standards and specifications.
 

We already achieved WRAS certificate in 2011, and obtained FM approval in early of 2012,
and UL for gate valve. Today, we have got many international famous certificate for drinking water such as WRAS, NSF, AS, CE on certain products, and our product range has expended to double eccentric butterfly valve, rubber disc check valve ,non-slam check valve, both clean water & sewage water air valve, hydraulic control valve and penstock and we always focus on water system valves.
 

In 2018 year, our big plan is developing pressure management valves which has been proved to be a very helpful tool and economic way to save the leakage rate with limited investment and get a fast return in couple months and power savings

In addition, we have a special project team to focus on custom design and special requirement
