A seal-off valve possessing several advantages for high-vacuum work has been devised by R. J. Richards of the National Bureau of Standards. The valve is designed so that its handle and stem can be readily removed and used with any number of seal-off seats, leaving only the closed valve seat on the e
stationary flexible element -this minimizes rotating components, eliminates shaft-to-box alignment problems and leads to improved face tracking and lower leakage. ?? premium grade carbon face -this leads to high resistance to blistering and fracturing and a high thermal conductivity reduces the pot
## Dynamic sealing power consumption is greatly reduced through the optimization of the friction face width and material selection. Specific attention to detail, llke surface finish underneath the O-ring and design of the antlrotation system, guarantees an increased service life. Lack of space ar
