Corrosion Resistance Water Air Release Valve For General Water Supply

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

Description:

RDCV is an entirely rubber encapsulated resilient disc seat and double flanges swing check valve with reliable back flow stopping, applicable for both clean and sewage water nets.

A 40 degree angle tilted seat design helps close very soon for shorter stroke and minimize the water hammer and slamming for lower stroke and flap above water flow.

EPDM rubber coated CS disc is strong with corrosion resistance, with nylon fabric inserted into makes disc hard, which prevents disc from damage and secure longer service life

Simple design, few internal components and big top cover makes inner cleaning, parts replacement and maintenance easier.

With big valve body, it keeps 100% full flow area and water head loss is reduced

Opening pressure only 0.2 bar fits for low pressure sealing test

DI valve body is 20-30% lighter than CI body and few internal parts easy for equipping and lowering the chances of impediment, the life cycle of RDCV is over 50000 times.

Features:

· 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 NBR rubber for superior sealing and corrosion resistance.
·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.
·The flap disc rises above the fl ow profi le reducing possible wear and damage.
·All iron parts are coated in fusion bond epoxy resin.
·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.

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
