M3P..FY

M3P..FYP

for chilled and low-temperature hot water systems or for

systems with media containing mineral oils (M3P..FYP)

• Fast positioning time (1 s), high-resolution stroke (1 : 1000)

• Positioning signal: DC 0...10 V or DC 4... 20 mA

• Fail-safe feature: 1  3 closed when de-energized

• Low friction, robust, no maintenance required

• Indication of operating state, position feedback and manual control

Use

The control valves are mixing or throughport valves with the ready fitted magnetic ac-

tuator for position control and position feedback. The short positioning time, high reso-

lution and high rangeability make these valves ideal for modulating

• control of chilled and low-temperature hot water systems

M3P..FY

• control or dosing control of fluids containing mineral oil (SAE05...SAE50), mineral-oil-

based diesel fuels, heat transfer oils

M3P..F

in closed circu

its.

• Temperature control in mixing circuits for motor oil circulation, screw-compressors

(compressed air) and fuel circuits for petrol and diesel oil

Applicatio

n examples

M3P..FYP

• High pressure control for the calibration of components for electronic injection

components

• Control of cutting-oil emulsion for industrial grinding machines

Control Spring return function Manual control The magnetic actuator can be driven by a Siemens controller or a controller of other manufacture that deliver a DC 0/2...10 V or DC 4... 20 mA output signal. To achieve optimum control performance, it is recommended to use a 4-wire connection. If the positioning signal is interrupted, or in the event of a power failure, the valve’s return spring will automatically close control path 1  3.

When sizing valves for media other than water, note that the medium properties • specific heat • density • kinematic viscosity differ from water. All variables depend on temperature. The design temperature is the lowest medium temperature in the valve. Note on viscosity Kinematic viscosity ≤ 10 mm2/s > 10 mm2/s Valve characteristic Viscosity may change considerably on temperature changes depending on the medium.

Engineering notes Conduct the electric connections in accordance with local regulations on electric installations as well as the internal or connection diagrams. Attention Safety regulations and restrictions designed to ensure the safety of people and property must be observed at all times! A strainer should be fitted upstream of the valve. This increases reliability. Mounting notes Two mounting instruction leaflets are enclosed with the valve: Ref. 35638 (valve) and reference 35731 (terminal housing).

Warning Disposal Under operating conditions within the limits defined by the application data, the actuator will become hot, but this does not represent a burn risk. Always maintain the minimum clearance specified, refer to "Dimensions", page 9. The actuator must not be disposed of together with domestic waste. This applies in particular to the PCB.
