Two-way valve for controlling cold, hot or glycol-mixed water, in domestic water systems or district heating, in the temperature range -5 ° C to + 150 ° C. The valves are pressure balanced (not from DN20-50, not DN15) and therefore handle the large pressure difference with low forces. The valves are used in conjunction with Regin RVAN5 actuators. Adapters for actuators of other brands are also available.
