High vacuum valve with a three-way configuration that can used in the manufacturing of manifolds, adapters, etc.
The glass valve body features precision-formed tapered valve seats and precision tooled external threads. Design of the cap and valve stem provides a non-rotating primary seal. The valve plugs are interchangeable between valves of the same bore size.
The valve plug has two PTFE seal rings that enclose Viton O-rings. This prevents exposure of the o-rings to corrosive gases and liquids. An additional Viton O-ring behind the PTFE seal rings ensures the vacuum seal. The tip of the valve plug has a machined O-ring shape and makes the primary seal to the barrel valve seat. The caps on the valve plugs are manufactured from Delrin.
