A rack-and-pinion air actuator turns the ball a quarter turn to open or shut the line, and the KF clamp ends connect and seal with a single clamp and centring ring \u2014 no bolts \u2014 so the valve installs and services fast on vacuum and high-purity facility piping.<\/p>\n<p>PTFE seats give a tight, low-friction shut-off, and the actuator is available double-acting (DA) or spring-return (SR), ready for solenoid valves and limit switches.
