Modulating control valve PN with magnetic actuator for hot and chilled water with positioning control and position feedback MP80FY MP00FY Mixing or straight-through valves DN80 and DN00 with magnetic actuator for modulating control of hot and chilled water systems. Fast positioning time ( s) High resolution (> : 000) > closed when de-energised With positioning control and position feedback Low friction, robust and maintenance-free se The MP...FY valves are mixing or through port valves with a ready-mounted magnetic actuator. The actuator is equipped with connecting electronics for positioning control and position feedback. If the power is off, the valve control path > is closed. The valve is suitable for straight-through or three-way applications and may be installed ONLY in a mixing arrangement. The short positioning time, high resolution and high rangeability make these valves ideal for proportional control of hot and chilled water systems. The low-friction, robust and maintenance-free construction make regular service unnecesary. Type summary The MP...Y valve is available in two sizes: MP80FY MP00FY Flanged valve with DN80 Flanged valve with DN00 Flanged valves up to DN and screwed valves up to DN0 see sheet CANE.

Ordering The valves are supplied complete with the magnetic actuator and the terminal housing. The blank flanges required for straight-through applications must be ordered separately (see 'Accessories'). When placing an order, please specify the quantity, product description and type code. Example: flanged valve MP80FY and blank flange Z/80 Technical / Mechanical design See data sheet CAN08E for a detailed description of operation. The control signal is converted in the terminal housing into a phase cut signal which generates a magnetic field in the coil. This causes the armature to change its position in accordance with the interacting forces (magnetic field, counterspring, hydraulics etc.). The armature responds rapidly to any change in signal, transferring the corresponding movement directly to the control disc, enabling fast changes in load to be corrected quickly and accurately. The valve position is measured continuously. Any disturbance in the system is rapidly corrected by the internal positioning controller, which ensures that the control signal and the valve stroke are exactly proportional, and also provides a feedback signal indicating the valve position. Stroke [%] 00 9.000 80 0 0 0 0 0 8 0 Control signal [V] If the power is switched off or fails, the valve control path (port > ) is automatically closed by the force of the spring. The valve stem is sealed with a maintenance-free O-ring gland. Manual adjustment Control path ports > can be opened mechanically to between 0 and approximately 90 %, by turning the handwheel clockwise. The manual adjustment facility can also be used as a mechanical method of low limit control, i.e. the valve will exercise its normal control function between the manually-set position and the 00% open position. For fullstroke automatic control, the handwheel must be set to 0 (the anticlockwise end-stop). Accessories For flanged valves: Close off port '' in straight-through applications. The blank flange kit consists of a seal, screws, spring washers and nuts.

Always disconnect the power before fitting or removing the terminal housing. The terminal housing is calibrated and matched to the actuator, and should be replaced only by qualified personnel. The MP...FY valve is suitable for straight-through or three-way applications but may be installed ONLY in a mixing arrangement. Vertical to horizontal mounting: Protection standard IP. The valve must not be suspended below the horizontal. The actuator must not be lagged. Recommendation Straight-through applications Water systems should be cleaned, flushed and treated in accordance with current good practice, as described, for example, in BSRIA Application Guides AG 8/9 and AG/9. For other relevant information, see also CIBSE Guide B (Section 7). Close off port '' with the type Z/... accessories, which must be ordered separately.
