From

0

The 2-port motor-driven ball valve RESOL VA22 is produced according to international standards and offers universal application possibilities in heating, warm water, solar and irrigation systems. A large number of application possibilities in the field of energy distribution is provided to the user.

Compact size, modern design, insulated actuator housing. Simple manual control for commissioning or emergency operation. Universal electrical connection by integrated relay (220 ... 240 V~). The control is effected via an on-off contact. The limit switch signal output can be used for control purposes (max. 1 A). The position of the ball valve is visible with the indicator flag (white). The actuator can be replaced quickly without demounting of the valve. No flow reduction, full flow according to the versions DN25 and DN32.
