Readings for Process
Contact Surfaces acc. to
ASME BPE 2016
Ra Max. = 0.51 μm (20 μinch)
Ra Max. = 0.38 μm (15 μinch)
Surface finishes of customized valve bodies may be limited in special cases.
1
Or any other finishing method that meets the Ra value (acc. to ASME BPE).
2
The maximum Ra finish achievable for pipe connections with an internal pipe diameter < 6 mm is 0.38 μm.
3
When using these surfaces, the bodies are marked according to the specifications of ASME BPE.
4
The surfaces are only available for valve bodies which are made of materials (e.g. GEMÜ material codes 40, 41, F4, 44)
and use connections (e.g. GEMÜ connection codes 59, 80, 88) according to ASME BPE.
Ra acc. to DIN EN ISO 4288 and ASME B46.1
