Boiler plant – return-temperature control valves

Introduction

Boiler plant control valves graphic

Typical for applications are: heat sources with minimum limitation of the return temperature (to avoid condensation); robustness for long service life; 3-position control signal; 3-port flanged valves; PN 16 pressure class.
