High Flow Capacity Dn50 Adjustable Pressure Relief Valve

Ductile Iron Pressure Sustaining Relief Valve Stainless Steel 304 Pilot Operated ​EPOXY Coated

Description:

A500 opens immediately when the pressure in the pipeline is over the safe level, thus relieving excessive pressure from the network. When the pressure returns to normal, the valve will close slowly, at an adjustable speed.

The valve can also maintain upstream pressure, regardless of flow rate variations. The valve will be in the “closed” position if the upstream pressure drops below the set-point and will fully open when the upstream pressure exceeds the set-point.

Pressure Rating: PN10,PN16,PN25,ANSI standard

Features:

• Non slam operation
• Simple and reliable design
• Easy installation and maintenance
• Low Resistance and high flow capacity
• Protection for sewage as well as clean water pumping systems

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
