Manual Injection Valve Replacement Parts
Manual Injection Valve Replacement Parts from Agilent Technologies
The rotor seal is the polymeric disc that makes a high pressure seal against the stator. The seal wears with use and needs routine replacement. Vespel blend rotor seals have an operating pH range from 0 to 10. Tefzel blend and PEEK blend rotor seals have a pH range from 0 to 14. Strong oxidizing acids such as concentrated nitric and sulfuric acids are not compatible with PEEK.
Stators are available in stainless steel and PEEK. The materials of construction have been researched and tested for their physical and mechanical strength. Only original, genuine Rheodyne replacement parts guarantee perfect operation of the valves.
