As pressure and/or temperature increases, ball and angle seat valves present an overall advantage due to standardization on highly resilient materials like metal housings and PTFE seats. However, the more expensive an angle seat valve becomes, the fewer its pressure rating, losing a number of its advantage within this category. A one-star rating contains the lowest relative value inside category while a three-star rating affords the highest.
For high-cycle-rate applications, like filling machines, start with exploring angle seat valves for pneumatic automation and solenoid valves for electric automation. These develop the highest lifecycle ratings, while ball and butterfly valves contain the lowest. In applications the spot that the valve may possibly open once or twice per day, how many life cycles are a smaller amount of priority, and ball and butterfly valves is usually still a great choice.
