ASTA R223 TERMOKOMPAKT is a single-seat two-way control valve of lightweight design, controlled by an electric drive, designed for precise remote regulation or shutoff of the flow of the working medium.
The new line of TERMOKOMPAKT valves was specially designed for use in cramped conditions at housing and communal facilities (boiler houses, central heating stations, individual heating stations) in sanitary and technical systems of buildings (heating, ventilation, water supply).
