Pre-Fabricated Flushing Bypass Assembly
for Plant Applications Hero Plant DN15-150
Description Hero Plant is a pre-fabricated, flushing bypass
arrangement for balance, control, isolation, and
operation of plant devices.
Flow is controlled by the AB-QM pressure
independent control valve to avoid over flow
and optimize the efficiency of terminal unit. The
flow rate can be accurately verified via MSV (DN
15-32) and via AB-QM (DN 40-150).
Application
Hero Plant is designed for use with air handling units, heat exchangers, heater batteries and all other
plant devices, where flow is controlled via a pressure independent control valve, and isolation, drain,
strain, flushing bypass, and flow measurement is required.
Key features include:
• A compact, pre-fabricated design
• Factory pressure tested assembly to PED
standard
• PN16 screwed connections DN15-50, and
flanged connections DN65-150
• A wide flow rate range for all applications
• Danfoss AB-QM type pressure independent
control valve for balance at full or partial loads
• A comprehensive compatible range of actuators
to enable it to be connected to a building
management system or other controller
• Strainer to remove particles from the system
and prevent plant performance deterioration
• Flow and return mounted drains for flushing
and quick draindowns
• Flow measurement function in all sizes
