Before using the valve, please read the entire manual carefully and ensure everything is clear. If in doubt, please contact Meca-Inox. The R2 2-piece ball valves should be used under service conditions within the range defined by the pressure/temperature diagram (classification is determined by the body and seat materials).
Ref.: UM-2PCS-MANUAL-R2-v0 MECA-INOX Date: 2024/03/15 R2 FLANGED 2-PIECE VALVE Edit: INSTALLATION AND OPERATING MANUAL Approval: Space requirements : Before positioning the valve on the line, ensure that the pipes do not exert stress on the valve. There should be no misalignment between the upstream and downstream pipes.
4 User Manual 4.1 Principle The R2 2-piece valve is primarily used for on/off applications. It allows fluid flow when fully open and cuts off the line when closed. Caution: It is not recommended to use the valve in an intermediate position, as this could cause seat deformation and eventually lead to leakage.
