This is the PV25MKA model. The body is made of lightweight aluminum. Both ends have KF25 flanges, the most common size for vacuum connections. It is a right-angle valve, meaning the inlet and outlet are at 90 degrees to each other. This saves space on your system.
Use it on roughing lines, backing lines, or anywhere you need manual isolation.

This is the PV40EKA model. It runs on 110-127V power (standard US voltage). The body is made of lightweight aluminum. Both ends have KF40 flanges, which fit 40mm tubing . This larger size allows much higher gas flow than smaller valves.
Use it on roughing lines, backing lines, or anywhere you need automatic isolation with higher conductance.

This is the “QDP40 MOTOR GASKET.” It sits between the motor and the pump body. Its only job is to create a perfect seal. It keeps oil inside the pump where it belongs. It also keeps dirt and moisture out.
Our REAR BRG PK1 is a direct replacement for the original Edwards part. It restores smooth operation and prevents major pump failure.
Our rear headplate is a direct replacement for the original Edwards part. It is precision machined to fit perfectly. Install this and your pump will be as good as new.
It is an oil distribution valve. Its job is to keep oil flowing in the right direction. When the pump runs, oil flows normally. When the pump stops, this valve closes and blocks oil from flowing backward into the pumping chamber .
Our retainer is a direct replacement for the original Edwards part. It fits perfectly and keeps your exhaust system working right.
This retainer is the metal ring or washer that holds the MSE seal in its proper position. It prevents the seal from moving or twisting. Without the retainer, the seal will not work correctly.
