Fire Protection Service UL FM Gate Valves For Outside Screw and Yoke Type and NRS Type for Fire Protection Service
Feature
The valve has been designed to prevent water within the body from leaking to the enviornment at the point where the stem passes through the bonnet.It is designed to be replaced by one person with the valve in the wide open position and under the rated working pressure
The body of a valve is of the straightway type and when the gate is fully open, a waterway diameter equal the inside diameter of a mating pipe
The body and bonnet of a valve shall be made of materials having strength, rigidity, and resistance to corrosion.
OS&Y gate valve are used indoors or in outdoors pits and NRS valves are used with wall indicator posts or underground with tee-handle wrenches or indicator posts attached or as roadway box valves

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
