High Vacuum Valve, Right-Angle with Tip O-Ring and PTFE Plug
(3)These valves use PTFE plugs for vacuum applications up to 5 x 10¯7 Torr. Designed with a precision external thread for fine control. Full open position is at 1 1/2 turns. The shaft is non-rotating and a seal is made with a Viton o-ring on a tapered seat. PTFE shaft can tolerate system temperatures of 230ºC.

High Vacuum Valve, Straight, Low Hold-Up, PTFE Plug, without Tip O-Ring
(2)This valve has bent side arms to minimize liquid hold-up that occurs with conventional valves. The PTFE shaft seals help protect the Viton o-rings from coming in contact with the system. This design reduces outgassing.

High Vacuum Valve, Right-Angle, Extended-Tip with PTFE Plug
(2)This valve has an extended tip on the PTFE plug that allows accurate valve control for both liquids and gasses. The Viton o-ring is shielded from direct exposure to gasses and liquids by PTFE ring seals.
