Pre-Fabricated Flushing Bypass Assembly

for Plant Applications Hero Plant DN15-150

Description	Hero Plant is a pre-fabricated, flushing bypass	Key features include:
	arrangement for balance, control, isolation, and	• A compact, pre-fabricated design
	operation of plant devices.	• Factory pressure tested assembly to PED
	Flow is controlled by the AB-QM pressure	standard
	independent control valve to avoid over flow	• PN16 screwed connections DN15-50, and
	and optimize the efficiency of terminal unit. The	flanged connections DN65-150
	flow rate can be accurately verified via MSV (DN	• A wide flow rate range for all applications
	15-32) and via AB-QM (DN 40-150).	• 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
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.
