ETVS – 2-way valve, DN15-40, gunmetal, 20 mm stroke
The ETVS valves are designed for control of cold, hot and glycol-mixed water, steam and district heating. They are pressure balanced (from DN20-50, not DN15) and can therefore handle high differential pressure with low force. The valves are intended to be used together with Regin’s RVAN5 actuators.
