DN50-DN300 SUFA Brand New Double Canister-Air Release Valves
Summary:
o The new composit-air release valves consists of big canister and small canister,
o When there is no water in the pipe,the canister in the body drops down to the full opening positio. Air is released from the discharge hole as water coming in,then water can be flled into the pipe immediately.When there isn' t anyair in the pipe,water comes into the valve,then it makes the canister go up to the shut-off position,and the big canisterlies in the position all the time.So that these improve water i transpoting capacity and reduce power exausting.
O Air is often dissolved into water,and then is released from water continuously when transporting,however,when reaching the quautity the small canister drops down,the airis released from the small canister. Otherwise the airgathered at the top of the pipe will lower the water transporting capacity of the pipe system.
o When there is negative pressure in the pipe,the big canister drops down,discharge hole is open,and then the valve draws in the air in good time ,so it can avoid working on the abnormal water supply by the negative pressure in the pipe.
Unique Design:
O The two canisters are made up of high strength,innoxious,
special engineering,with concise structure I ethereal weight,steady and Reliable exausting.
o Body,Cover,Dust preventing cap,inside and outside epoxy resin powder coating,no iron exposed.internal accessores made of stainless steel and splecial engineering plastic,resisit rot,insure good purity.
0 Sealing seat,made of bronze,improves the abrasion capacity, and prolong the life.
Excellent corrosion protection:
o inside and outside epoxy resin powder coating,no iron
exposed.
Reliable health nature:
o Epoxy resin powder is up to the health standard GB17219-1998
Scope of application:
o Pipe for water transportation and pump s existence,to be installedat the highest point of level pipe.
