Stable Sealing Surface Guide ring A unique guide ring on the piston rod eliminates lateral motion of the poppet, greatly increasing seal life and reducing particle formation with a stable work surface. Low particle generation Piston bumper Prevents Micro-Bubbles Diaphragm (PTFE) A bumper absorbs piston momentum to minimize impact-induced particles. Special diaphragm construction insures gentle opening and closing that prevents the formation of micro-bubbles. Back-pressure resistance and long life Buffer Minimal dead space The diaphragm is supported by a buffer that minimizes deformation, which...
