KEOFITT W9 USER MANUAL V.4 PAGE 27
6.5 Surface nish
Internal: Electropolished
Ra<=0.5µm / 20µinch
The mean and standard deviation are statictical valves measured for a given production batch:
Ra(mean) = 0.2µm / 8µinch
Ra(std.deviation) = 0.08µm / 3µinch
Valves with internal electropolishing are identied by an E preceding the serial
number e.g. E12345678
External: Electropolished
The surface roughness is measured for each valve at 4 critical places (the valve body process
surface, the valve chamber and each of the two ports).A serial number identies each valve body.
A specic surface roughness certicate is supplied with every valve. A general surface nish
certicate copy is available on www.keott.dk
6.6 Viscosity
Viscosity range: 0-1000cP, with particles up to 3mm in diameter.
Higher viscosity liquids may be sampled, only will the sampling take longer.
