Butterfly and single-seat valve service kits, seat rings, disc bushings and actuator parts for CIP-cleaned dairy lines.
A photograph of the nameplate is enough. Part numbers are not published on this site. The nameplate carries the model, the build and the serial, and those three identify every consumable and wear part on the machine.
Where the nameplate is unreadable, a photograph of the equipment and the plant tag number are normally sufficient. The quotation states the genuine part, its origin and its lead time.
A service kit specifies the elastomer by kit number. The compound is a separate part rather than an option on the same part.
Seat performance in a CIP circuit is governed by the cure system of the rubber, which is rarely stated on an aftermarket component.
| Property | Peroxide-cured | Sulphur-cured |
|---|---|---|
| Continuous service | to approx. 150 °C; steam to 180 °C+ | approx. 120 °C max |
| Compression set | approx. 19% after 70 h at 100 °C | Hardens in service |
| Hot caustic / nitric CIP | Minimal swelling | Degrades faster |
| Product contact | Clean | May alter the properties of fluids in contact |
| Seat replacement interval | NOT PUBLISHED. Determined by CIP cycles, temperature, product and actuation frequency. | |

Both compounds are correctly described as EPDM. The panels show retained sealing force over six hundred CIP cycles for each cure system.
