A two-piece 316 stainless steel ball valve fitted with a rack-and-pinion pneumatic actuator and
\n terminated with NW50 (ISO-KF) quick-clamp flanges. The KF clamp ends connect and seal with a single
\n clamp and centring ring \u2014 no bolts \u2014 so the valve installs and services quickly in vacuum and
\n high-purity facility piping. PTFE seats give a tight, low-friction shut-off, and the actuator
\n delivers fast quarter-turn open and close. Available with double-acting (DA) or spring-return (SR)
\n actuators, and ready for solenoid valves and limit switches.<\/p>\n
