Page 9: Product Description
Product description PRODUCT DESCRIPTION The type 2871 direct-acting proportional valve is used as an actuator for process control loops. An elastomeric seat seal makes the valve close tight up to the orifice-specific nominal pressure (integrated shut-off function). The magnetic core of the valve is stored without friction, which results in outstanding positioning behaviour. -
