Manufacturer guidance

• This module is fitted with a stainless steel perforated screen with drain-cock / vent facility and pressure tapping point.
• The screen may be removed for cleaning by undoing the bonnet. Replacement screens are available.
• It is recommended that the gasket and ‘O’ rings are replaced during routine servicing.
• Re-tighten the bonnet to the recommended torque.
• The strainer may be back or forward flushed by setting the bypass valve to the appropriate mode and loosening the drain-cock about two to three turns.
• The drain cock has provision for attaching a drain hose.
• Avoid over-tightening the drain-cock, which requires only low torque to seal.
• The load can also be flushed in the back-flushing mode.
• Monitoring the pressure drop across the load can be facilitated by taking a reading across FODRV (upstream - red tapping point) and the tapping point provided in the strainer.

Manufacturer guidance

• All balancing valves require four clockwise turns of the ‘Microset’ hand-wheel from fully open to closed position.
• A highly visible window indicates the number of complete turns of the hand-wheel from fully open (four) to closed (zero) and a numbered ring indicates the division of each turn in tenths from zero to nine.
• A total of 80 distinct settings are available.
• The ‘Microset’ hand-wheel can be removed and repositioned on the valve spindle in any one of six positions to allow ease of scale reading.

Manufacturer guidance

The ‘Dominator’ has two unions fitted to allow for orientation and handing of the FODRV, strainer and bypass valve.

Manufacturer guidance

• Steel tube – cut square and de-burr internally and externally, thread to BS21 and fit to Dominator using PTFE tape to BS7786:1995 or other recommended jointing compound.
• Whilst fitting pipe and / or adapters, appropriate sized wrenches should be used to take the reaction force generated on the valve body when making the joint.

Manufacturer guidance

• The valve may be installed directly or remotely to a load (typically a Fan Coil Unit).
• The direction of flow should be such that the return from load enters the ProBalance (FODRV) on the flow measurement side.
