Backflow Prevention Nozzle Check Valve With Anti Water Hammer

Nozzle Check Valve With Anti Water Hammer And Backflow Prevention Function

Nozzle Check Valve with anti water hammer and low Head Loss function

Description:

Non Slam Check Valve is usually installed as protection against reverse flow when power failure in areas where noise pollution or water hammering is a critical issue. It has two outstanding features: anti water hammer and low head Loss. The faster closing function can decrease the reverse speed of water to minimize water hammer.

Features:

· Extremely short stroke can help quick closely

· Diffuser design- lowest head loss and streamline flow

· Spring hidden on back side of disc prevent clogging

· Bronze bearing extends long life service

· Disc will positively close before reverse flow, and maximize the closing speed up to 0.2 Sec.

· High strength ductile iron body used for durability and less weight.
· Advanced dynamic design of single body with diffuser provides streamline flow and assures lower head loss.
· Stainless steel spring hidden in the diffuser under protection while valve in operation.
· Comply with EN 558-1, ISO 5752 and EN 1092-2, ISO 7005-2 flange dimension.

· No leakage of rubber disc seat.

· Installation can be vertical/horizontal/inclined operated.

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
