How to distinguish soft seal ball valve and hard seal ball valve purposes
Let us look at the hard seal ball valve and soft seal ball valve in the structural mechanism of the different: the hard seal ball valve is formed between the metal valve seat and the metal ball seal, machining accuracy and high technical requirements, generally used in high temperature and pressure Conditions and media above, usually 250 ° C or 35MPa above conditions. Soft seal ball valve is a metal ball and non-metallic seal between the valve seat, such as nylon or PTFE and PPL para-benzene, manufacturing requirements are different. The choice of soft and hard seal ball valve depends mainly on the use of technology media, temperature and pressure, usually containing solid particles or wear or temperature is higher than 250 degrees the best choice of medium-hard ball valve, the valve diameter greater than 50 larger pressure is also considered Open the valve torque size, torque should be used when a larger fixed ball valve, regardless of the seal level of soft and hard seals can reach 6. General temperature is less than 250 degrees, the media medium without particles, you can choose soft seal ball valve.
