Limit Switch Boxes for BVA300 Series Actuators

Description

LSB limit switch boxes are normally used for indicating valve open or valve closed position. They also allow switching points to be adjustable

over the full range of actuators. There is an open/closed valve position indicator mounted at the end of the switch box axis, at the top of the

cover. LSB's include a stainless steel linkage kit for direct mounting to BVA300 series actuators.
