Submitted by nestorb on Tue, 2006-11-07 06:29.

JV series isolation valves from Nor-Cal Products are available in right-angle and in-line bodies in aluminum or stainless steel with NW16, 25, 40, and 50 flanges. Some models are rated up to 10 million operating cycles, designed for the high-cycle requirements of semiconductor equipment manufacturers and for ultrahigh-vacuum roughing. The JV series offers a unique manual actuator for coarse throttling, which allows partial opening by specified and repeatable intervals. Also available are pneumatic operators with an optional air solenoid kit and electromagnetic actuators for systems that do not have compressed air sources. Other options include position indicators and, for electromagnetic models, snap-on coils and a memory function on power interruption.
