Guide ring Eliminates lateral motion of the poppet which reduces internal leakage. Piston damper Absorbs piston momentum to minimize impact-induced particle generation. Diaphragm (PTFE) Protects diaphragm from deformation and damage due to back pressure. Special diaphragm construction ensures gentle opening and closing that prevents the formation of micro-bubbles. Integral fittings construction LQ1 Minimal residual liquid Offers quadruple seal construction. Nut lock mechanism—no additional tightening required. High flexural strength. Different tubing sizes can be selected. Residual liquid is...
