Page 3: Introduction
1. Introduction Industrial valves made by company ROFI S.A.R.L. are designed according to International norms such as DIN-Standards, EN-Standards and according to the Technical Rules like AD and the European Pressure Vessel Guideline 97/23/EG, etc.. Design, manufacture and testing of these valves was carried out on condition that the valves are operated under normal operating conditions. -
Page 4: General Information
The guidance for installation, operation and maintenance of ROFI Valves contained in this manual, is intended for use with our standard products. It may also be used with special valves provided the special additional instructions are observed. These are available on request. These instructions should ensure trouble-free fitting and safe operation of our valves, and form also the basis for any guarantee claims that might arise. -

(2 / 3) – EN 50014. The installation of the electrical device must be in accordance with DIN VDE 0100 and EN 60079. QM-Nr: FB_BMA_01-R-0804engl_3 Erstellt/ Prepared : am/ on:19/11/2015 Genehmigt/ Approved: am on19/11/2015 7 / 16 by ROFI S.A.R.L. -

Strainers must be fitted that way that the screen shows down. Upon fitting the flow direction has to be considered (directional marker). QM-Nr: FB_BMA_01-R-0804engl_3 Erstellt/ Prepared : am/ on:19/11/2015 Genehmigt/ Approved: am on19/11/2015 8 / 16 by ROFI S.A.R.L. -
Page 9: Installing Position
In order to avoid undesirable pressure surges when opening large valves with high differential pressures, or to warm up gradually the connected pipelines, suitable bypasses opened before the main valve should be provided.

Page 11: Gear Operated And Actuated Valves
The specific torques of electric actuators normally are set in the factory. The closing of ROFI valves is controlled by torque switches, eventually additionally secured by limit switches. Opening of the valve is generally controlled by limit switches only. -
Page 12: Venting
Seal tightness should be checked after a while since seals and bolts etc.. are apt to settle during initial operation, especially at high temperatures. QM-Nr: FB_BMA_01-R-0804engl_3 Erstellt/ Prepared : am/ on:19/11/2015 Genehmigt/ Approved: am on19/11/2015 12 / 16 by ROFI S.A.R.L. -

Page 14: Recommended Lubricants
It is for the valve operator to specify the intervals for lubrication of the spindle thread and of the thread bushing (depending on the operating conditions of the valve).
