Ball valve model
Thread Content
Could you please tell me what the CQ41PPL-16C model ball valve refers to, and what is its material?
It is a waste discharge ball valve; the sealing material of the valve body is PPL, while the material of the valve body itself is cast iron
CQ41F= is the valve model: a high-temperature, oil-resistant ball valve; PPL: the material used for sealing the valve body – polyphenylene; -16C: the valve body is made of cast iron or carbon steel.
I still haven’t found any reliable information regarding this C; I agree with the others above
CQ41PPL-16C: The first ‘C’ denotes a ball valve designed specifically for tank trucks, also known as a ball valve with no dead zones for discharge. Q: Ball valve; 4: Flanged connection; 1: Floating ball straight-through type; PPL: Valve seat made of polyphenylene; Operating temperature: 300 degrees; 16: Nominal pressure, i.e., 1.6 Mpa; C: Material is cast steel (carbon steel)
The standard method for indicating valves in China is JB/T308. This standard does not include any notation with a ‘C’ before ‘Q’, so the meaning of this ‘C’ can only be determined by those who are responsible for classifying valves; others can only make guesses
