Product Description

Electric Flow Control Valve

Model: 3131,External Thread

Product Description

Fan-coil control valves are used for controlling the flow of hot or cold water in heating and air conditioning systems. They are ON/OFF operated by electric actuators with max. stroke of 4 mm,such as electrothermic actuator. It can be used both as mixing and diverting valve.

The actuator is made for either 220V or 24V supply in normally closed

APPLICATIONS

The valves are used for diverting/mixing, the heat transfer fluid to a heating or air conditioning system as required by the room thermostat (or timing thermostat).

The 3-way fan-coil valves series 3131, thanks to the special configuration of the plug controlling the by-pass flow, can be used equally well as diverting or mixing valves (thus optimizing to the full the various plumbing requirements in assembly).

MEDIA
These valves can handle the following types of media:
- Fresh water / Potable water
- Closed systems
- Water with antifreeze additive (glycol ≤ 50% mixture)

TECHNICAL DATA

Max pressure, models w. constant Kv 16 bar
Max pressure, models w. variable Kv 10 bar
Min. fluid temperature 4°C
Max. fluid temperature 110°C
Plug stroke 4 mm
By-pass leakage 0,02 % Kvs

Valve thread connection: External Thread, G thread, DN32,DN25
Actuator connection Threaded ring nut M30 x 1.5

MATERIALS

Body: forged brass

Stem: Stainless steel

Spring: Stainless steel

Plug Rubber: EPDM

OPERATION

Operation of the fan-coil control valves 3131 is through the movement of the plug which shuts off the heat transfer fluid: the ON/OFF action of the plug is controlled by the actuator whose internal motor consists of a wax thermostatic element activated by a PTC thermistor against a signal sent by a room thermostat (or timing thermostat).

When coupled to the normally closed actuator, under rest conditions (actuator not energized), the valve becomes

• normally closed (NC) (straight way closed and by-pass open); when the actuator is energized, the valve is opened.

When coupled to the actuator, under rest conditions (actuator not energized), the valve remains

• normally open (NO) (straight way open and by-pass closed ); when the actuator is energized, the valve is closed.

The reliability of the fan-coil control valves 2131, 3131, 4131 is guaranteed by the 100% testing on the production, which checks the hydraulic seals of the valve body and its components towards the outside and the seal of the plug in its flow shut-off function.
