What is an angle valve？It is necessary to know so many decoration materials for decoration，It feels great too。
Let's first understand what is an angle valve
Because the pipes are formed at the corners90°shape，Therefore, the angle valve is also called the angle valve. and angled water valve。
What are the types of angle valves？
Triangle valve can generally be based onhot and cold、open method、material、SpoolFour aspects to distinguish。
1、According to hot and cold，which is“cold”and“hot”two（in blue、red mark distinction）。
△ Hot and cold angle valve
Cooling and heating triangle valves in the same model from the same manufacturer，Most of the materials are the same，no essential difference。The main purpose of marking the heating and cooling triangle valve is to distinguish which is hot water，which is cold water。Some low-grade slow-opening triangle valves are rubber-ring spools，Rubber ring material can not bear90°hot water，need to be divided into hot and cold。
2、Distinguish from the way of opening，Can be divided into fast opening and slow opening。

△ Zinc alloy angle valve
brass：easy to process，Strong plasticity；have hardness，Anti-bending and anti-torsion。
alloy：low cost；The disadvantage is that the bending resistance is low，The surface is easy to oxidize。
iron：easy to rust，polluted water。It is not recommended to use in today's environmentally friendly and low-carbon society。
plastic：low cost，Not easy to use in the very cold north。
△ All copper angle valve
4、From the valve core，with ceramic spool、Ball spool、Rubber Rotary Spool、Engineering plastic valve core。
Ceramic valve core：The switch feels smooth and lightweight，long lasting，Moderate cost。Home use is more common。

Ball spool：The caliber is larger than the ceramic spool，Does not reduce water pressure and flow，Easy to operate（rotate90fully open/All closed），STHThe spool is chrome plated。The advantage of chrome plating is high hardness and wear resistance，long lasting，avoid patina。High recognition without ceramic spool。
Rubber Rotary Spool：It's out now，The reason is that switching on and off is very time-consuming and labor-intensive，At present, the family rarely uses the angle valve of this material。
Engineering plastics（ABS）：Low cost of plastic valve core，Quality is not guaranteed。
What are the dimensions of the triangle valve？
①、3/8Refers to3Minute，can receive3split water pipe（Generally used on the faucet3Divided hard pipe）。
(delta scald guard tub shower valve trim kit polished brass)②、1/2Refers to4Minute，can receive4split water pipe（Faucet for countertop water、toilet、4Separate water heater、Jacuzzi、Overall shower room and shower screen，General home use1/2）。③、3/4（Straight valve）Refers to6Minute，can receive6split water pipe（Rarely used at home6Split right angle triangle valve，household water mains and6Water heaters with separate water inlet and outlet are commonly used6Split straight valve）。
What are the functions of the angle valve?？
1、Generally speaking，At home we all use it asswitchto use。When a water pipe in your home is broken or a faucet is leaking，When changing the faucet，close the valve，You can save the step of closing the main valve.。
2、Regulate water flow，When the water pressure is too high，Turn the triangle valve down slightly，The water flow won't be so big。new house plumbing，This angle valve must not be installed less，This can play a very important role in cleaning plumbing。
