Description
The Schneider Electric (Barber Colman) PNV-103-3 Lower Housing is a building element that is used to support and shield interior components of a pneumatic valve actuator assembly. It is used to create the lower part of the actuator body that contains internal components like the diaphragm and linkage components fixed in it but can move in response to air pressure when it is used in hydronic and air-handling HVAC system. The housing is mounted under the actuator assembly where it fits into the actuator body of MK-2690 and is connected to the valve control mechanism. Actuator components should be properly enclosed to ensure the stable mechanical operation.
