The "angle seat valve" combines all of these features. Common disadvantages of widely used valves include: - In the case of ball valves, with each opening and closing, the material between the ball (valve body) and the valve body wears down. As wear progresses, it will leak from that area and no longer function as a valve. - In the case of solenoid valves, the flow path is complex and the pressure loss is significant, so while the solenoid valve itself is compact, it requires a large force from the pump. The "angle seat valve" compensates for these disadvantages and possesses characteristics suitable for steam and liquid processes, making it possible to achieve applications closer to the ideal.
