VTA570

The 3-way ESBE VTA570 can be utilized in a mixing or diverting application for hydronic closed looped systems (not for potable water). Typically, this thermostatic control is used as a non-electric alternative for a 2-pipe changeover diverting application.

KOVM mixing valve

KOVM mixing valve bodies are designed to maintain room temperature by controlling hot (or chilled) water flow through radiators, fans, convectors, etc. Due to the KOVM’s unique bypass design, a constant system flow is achieved regardless of the room’s heating (or cooling) requirements. Therefore system pressures and flow rates are automatically kept constant without the need for pressure controlled bypass valves.

Actuators for rotary valves

Motorized rotary actuators specific to ESBE rotary valves that operate on a variety of input signals.

Rotary valves

ESBE Rotary valves are designed for regulation of flow temperatures in hydronic heating or chilled systems.
