Jump to:
+44 (0)1737 766391

Application

Differential pressure regulator (differential pressure control).

For use with water and other liquids, air and non-flammable gases.

  • Suitable for district heating systems according to DIN 4747-1 (fulfills AGFW requirements for components in house substations).

Description

Differential pressure regulators, DN15–50.


Features and benefits:

  • Consisting of valve and closing actuator; valve closes when the differential pressure rises.
  • Single-seated valve with balanced plug.
  • Set point adjustable between 0.1 and 4 bar.
  • With set point indication (DN15 to DN32 only; set point range between 0.1 and 1 bar, or 0.1 and 0.5 bar).
  • Type 45-4 includes internal overload protection (excess pressure limiter) in the actuator.
  • Suitable for district heating systems according to DIN 4747-1 (fulfills AGFW requirements for components in house substations).
  • With connection nuts and welding ends.
  • DN15, DN20, DN25, DN32, DN 40 or DN50.
  • Part of the Series 45 Self-operated regulators range.
