how to choose good quality gas valves is very important for our life. Come on, follow me please!

First,Please check if the gas valves has been certified by CSA or UPC, then check the list number on their website to make sure if it is true. Both of them works means the quality of the good shall be good.

Second,if the good you find has not been certified by any famous company, don't worry, we also can keep find as below:

1)Check the the handle of valve, if the material is stainless steel 304. then best

 if the material is steel with chrome plated, then the quality is good

if the material is steel with nickle plated, then the quality is unsure, then we look blew

2)Check the drawing which is coming with the gas valve, if the gas valve is seal by TWO O-rings, that means good.

3)Check the seat ring beside the ball, if the seat ring is made by PTFE not plastic, that means good

4)If you can,check the ball, it should be very smooth, that means good

5)Check the body of the valve, if it has been heat treatment, that means good.
