Bypass Valve - Screwed 45-6 - Differential Pressure Regulator

Verified by manufacturer 7 days ago

DN15

SAMSON Controls Ltd Variant:

Differential pressure regulators, DN15–50 for installation in a bypass pipe or short-circuit pipe.

Jump to:
+44 (0)1737 766391

Application

Differential pressure regulator (differential pressure control) for extended piping systems and industrial applications for installation in a bypass pipe or short-circuit pipe.

  • For use with water and other liquids, air and non-flammable gases (provided these do not cause the materials used to corrode).

Description

Differential pressure regulators, DN15–50 for installation in a bypass pipe or short-circuit pipe.


Features and benefits:

  • Consisting of globe valve and actuator; valve opens when the differential pressure rises.
  • Low-maintenance proportional regulators requiring no auxiliary energy.
  • Single-seated valve with balanced plug.
  • Ready-assembled regulator, control lines do not need to be routed on installation.
  • Replaceable operating diaphragm.
  • Low overall height achieved by suing a compact spring assembly.
  • Suitable for water and other non-flammable liquids or gases (provided these do not cause the materials used to corrode).
  • DN15, DN20, DN25, DN32, DN 40 or DN50.
  • Part of the Series 45 Self-regulated regulators range.


Also available with connection nuts/ welding ends, or flanges. Consult manufacturer for details.
