Product Overview
Description
Product Description
Application:
In ventilation and air air conditioning plants for control on the water side and automatic hydraulic balancing of terminal units, such as fan coils, air handling units, and in heat exchangers for heating or cooling.
In heating zones like self-contained heating systems, apartments, individual rooms, etc.
Parameters:
Combines an externally presettable adjustable valve, a differential pressure control valve and a full authority modulating control valve.
DN15~200
Pipe connections
SMU12... (DN15~DN50):
Internal thread BSP (ISO7/1) PN25 SMU62... (DN65~DN200):
Flanged (ISO7005-2) PN16 PN25 Body materials:
SMT12...
(DN15~DN32): hot-pressed brass
(DN40~DN50): stainless steel
SMT62...
(DN65~DN200): nodular cast iron
Features:
The maximum flow can be preset arbitrarily
according to the actual flow demand, making the control more precise and adjustment more convenient
The presetting function has no impact on the stroke, regulation characteristic remains
unchanged regardless of preset flow
The flow control is only related to the electric control valve opening and is not affected by the fluctuation of the system pressure difference
Optional with pressure test plugs (P/T plugs) (It must be selected before delivery)
Can be equipped with linear electromotor actuators,such as: On/Off or 3 point or
DC0-10V or DC4-20mA.
