+44 (0)1737 766391 Website

Application

Flow rate control in district heating systems or extended heating or cooling networks.

For use with water and other liquids, provided these do not cause the materials used to corrode. Suitable for treated water up to 150°C.

Description

Combined self-operated regulator for flow rate with additional electric actuator.


Features and benefits:

  • Closes when the flow rate rises.
  • Device combination consisting of valve, diaphragm actuator, adapter for flow rate adjustment, and electric actuator.
  • Actuator optionally with or without fail-safe action.
  • Valve 2423: Single-seated valve with balanced plug.
  • Flanged connections.
  • Valve size DN15–250.
  • Pressure rating PN16, PN25 or PN40.
  • Flow set point ranges from 0.8 to 300 m³/h.


Flow regulator with thermostat connection also available (Type 2489), consult manufacturer for details.

Manufacturer guidance

Consult manufacturer's literature for further details.


Special version with two diaphragms (for increased functional safety) also available.

Accessories

None.
Compression-type fittings.

Guidance for specification option:

Straight stud ends with parallel thread according to DIN 2353 to connect control lines to the valve.

  • G¼ threaded connection for pipe with 8, 10 or 12 mm outside diameter.

Screw joint with restriction.

Guidance for specification option:

Pipe screw fitting with restriction to dampen vibrations in the control line.

Various cross-sections available depending on the volume of the diaphragm actuator.

Needle valve.

Guidance for specification option:

To shut off the control lines and also to dampen any vibration.

  • Steel body (stainless steel on request).
  • G¼ female thread.

Compensation chamber.

Guidance for specification option:

Used to protect the operating diaphragm in the actuator against high temperatures. Required for medium temperatures above 150°C.

  • Maximum permissible pressure 40 bar (gauge).
  • Case made of sheet steel S235JR (1.0037). Two assembled condensation chambers with mounting brackets form a cool-down battery.
  • Control line connections with two compression-type fittings for pipes with an outside diameter of 8 mm (special version: for pipe with an outside diameter of 10 or 12 mm).

Double adapter for regulators.

Guidance for specification option:

For connection of a second control thermostat or a second actuator. The double adapter is mounted between the bellows housing and the actuator to apply a second controlled variable, e.g. to limit the temperature.

Orifice plate.

Guidance for specification option:

To create a differential pressure Δp.

Required when using a differential pressure regulator as a flow regulator.

  • Available for DN 15 to 300.
  • Material: stainless steel 1.4571.

The orifice bore diameter is calculated based on the technical data.

The orifice plate is mounted between the inlet flange of the differential pressure regulator and an additional welding neck flange.

Welding neck flange with compression-type fitting.

Guidance for specification option:

For flow control with an orifice plate.

  • Valve sizes DN 15 to 300.
  • Pressure rating PN 16, 25 and 40.
  • Control line connection: compression-type fitting for pipe with 8 mm outside diameter.
  • The dimensions correspond with DIN EN 1092-1, flange type 11. For simultaneous measurement and indication of the flow rate, the use of an orifice plate (orifice flange) and a flow meter must be used.

Control line connection.
Ready-mounted control line with accessories (mounting kit).

Guidance for specification option:

For transmitting the pressure to the diaphragm of the regulator.

The manufacturer recommends using a stainless steel 8 x 1 mm tube as a control line.

Optionally, they offer various regulator models with ready-mounted control lines, needle valves and compensation chambers.


Consult manufacturer's literature for details of the various options and configurations.
