Notes Engineering The VBG31.. slipper valve should preferably be used in mixing applications. In systems where oxygen can enter the hydraulic system, there is an increased risk of corrosion which can cause the valve slipper to seize. Mounting variants Boiler flow from left Factory setting Mounting 4232H02 4232H01 Boiler flow from right Re-position the valve slipper, scale plate and manual adjuster, as described in the mounting instructions for VBG… slipper valves.
PAGE 6
Commissioning When commissioning the slipper valve, ensure that the position and rotation of the valve slipper are appropriate for the system concerned (see "Engineering").
