Applications

Changeover valves with isolation blocks are used in laboratory and industrial high vacuum systems to switch between pump configurations while reducing vibration transmission to connected equipment. These valves were commonly deployed in vacuum lines serving analytical instruments, research apparatus, and semiconductor processing equipment. The isolation block decouples mechanical vibration from the vacuum pump, protecting sensitive downstream components.

Condition: Used
This Edwards High Vacuum Changeover Valve with Vibration Isolation Block has been inspected and is in good condition. The valve body and isolation block show normal surface wear consistent with prior use — some light scuffing and minor paint marks on the cast aluminum body — but there are no cracks, broken fittings, or missing hardware. The flexible hose section and knurled manual actuator knob are intact. The black anodized vibration isolation block is present with its port fitting in good shape.
