Operating media

Water

Typical applications

  • Leakage reduction
  • Pressure management
  • District metered areas
  • Smart network management

Approvals

WRASISO 9001

Features

  • The P26M provides time-based pressure management, automatically reducing network pressure during low-demand periods (typically overnight) and restoring pressure for daytime demand
  • Lower overnight pressures significantly reduce background leakage and burst frequency
  • The time-based actuator requires no external power or SCADA connection, making it a fully hydraulic, self-contained solution

Description

The P26M provides time-based pressure management, automatically reducing network pressure during low-demand periods (typically overnight) and restoring pressure for daytime demand. Lower overnight pressures significantly reduce background leakage and burst frequency. The time-based actuator requires no external power or SCADA connection, making it a fully hydraulic, self-contained solution.

Selection notes

This control valve is supplied for flanged installation.

Sizes run DN50 to DN800, in PN10, PN16, PN25, ANSI 125, ANSI 150.

The body is EN-GJS-500-7.

Seat and trim options are AISI 304 and AISI 316. The seat, not the body, usually sets the temperature and medium limit, so confirm it against the service before ordering.

Stated service media include water.

It is catalogued for Water & Wastewater.

Working temperature is -10°C to 80°C.

Built to EN 1074-5, BS EN 1074-5, BS EN 558-1, ISO 5208 and BS EN 12266-1.
