Inquiry (采购产品): seek high-speed valve for 4-inch air line I am seeking a high-speed valve for a 4-inch air line. The maximum upstream pressure is 300 psig, and the lowest upstream operating pressure is 8 psia or less. The downstream pressure is a hard vacuum. I would like the valve to open in less than 0.2 sec. under all conditions if possible. It can take several seconds to close, as we seek to dump the upstream air to vacuum on command. Please let me know if you can supply such a valve or know of anyone who can. It's for our Mach-6 wind tunnel. **** Hidden Message ***** Steve Schneider IN 47906 USA Company: Purdue University Phone: 765-494-3343 E-mail: steves@purdue.edu **** Hidden Message ***** steves@purdue.edu
