MVS Guidance for Application

• Connectors suitable for system ends
• MVS are available with factory fitted VSH XPress, VSH Tectite or Kuterlite adapters

Recommend

• Compact and economical 40 -120mm centres
• Allows forward flushing where the system is flushed before letting water through the fan coil and control valve, clearing debris out of the inlet pipework
• Allows reverse flushing where water flows backwards through the MVS and fan coil. Useful to flush debris out of a new fan coil unit without the risk of contaminating the control valve

Please Note:

BSRIA

• Compliance to BSRIA BG 29/2012 drain arrangement
• Additional pair of drains fitted between the MVS and the fan coil
• Complies with BSRIA recommendations
• Protects the entire MVS from contamination during flushing of the fan coil

A capped end can also be fitted with optional air vent or drain cock

• Rotatable drain spigot for access from any angle
• Manual air vent

Recommended

• Filters inlet flow protecting fan coil and control valve from debris
• Includes 2 ball isolation valve so filter can be cleaned without draining system
• Available in standard and extended handle variants
• Test points are available as an optional extra to allow the strainer to be checked for blockages

Please Note:

• If suitable separate strainers are fitted elsewhere in the system then the strainer can be omitted from the MVS assembly
• PY always recommend that the PICV is protected by a strainer. Failure to do this can permanently damage the MVS

Any system over 50 fan coils we recommend the use of PICV

• Comfort integration via Room Thermostat or Building Management System integration through range of actuators
• PICV - 3 valves in 1 (Flow regulation, Pressure regulation, 2 port valve)
• Venturi based flow measurement system (accurate to ±5%)
• Pegler Proflow is unique as it can prove the flow rate

Smaller systems we recommend FODRV

• Flow regulation, Flow isolation
• Venturi based flow measurement system (accurate to ±5%)
• Orifice based flow measurement system (accurate to ±10%)

• The terminal connection installation can be variable from FCU centres and accessible for maintenance
• Enables centres to be flexible from 40mm to 120mm
• Pegler flexible connector option enable a direct fitment to a Fan coil without the need for further components

Please Note:

• Factory fitted VSH XPress and VSH Tectite adaptors also available

• Actuators are also available with on/off and modulating options

• Provides comfort integration via room thermostat or building management integration
