Inherent flow characteristic
Equal percentage.
Tightness
Tightness is tested in the direction by the arrow, e page 4,according to ISO 5208. The standard tightness of a metal-ated gment valve is 10 x ISO 5208 Rate D. This tightness corresponds to 1/100 of max at leakage allowed by ANSI/FCI 70.2 Class IV .
Valve pressure and leak test
All valves manufactured by Metso Automation undergo pres-sure testing. The test pressure of an R-ries valve body is 1.5 x the pressure rating and the test pressure of a at is 1.1 x the maximum permissible shut-off pressure. The test medium is water containing a corrosion inhibitor .

ACTUATOR MOUNTING POSITIONS
Note!
1. The most common positions are shown here. Should you wish to u some other mounting position, plea contact the nearest Metso Automation reprentative.
2. The mounting position can be changed at the site without extra accessories. See bulletin 3 R1L 71 for mounting,operation and maintenance.
3.If no mounting position is given, the actuator is mounted at the factory in position A-VU.
4.Following mounting positions are not possible A-VU, A-HU, A-HR, A-HL, A-VD, A-HD for following valve units:R2DS04/06-B1J10R2DS10/12-B1J20R2DS12/14-B1J25
