Johnson Controls D-251-6002 2-Pneumatic Actuator Diaphragm

The Johnson Controls D-251-6002 is an essentialdiaphragm replacement part for pneumatic actuator applications in HVAC systems. This single-piece diaphragm is specially made from high-quality rubber material that is, highly resistant to abrasive wear that in fact enhances its durability. The diaphragm controls the pressure of air in pneumatic actuators. It employ the pressure in terms of compressed air to achieve mechanical movement. This diaphragm bends in response to the variation of the air pressure, which influences the actuator. This movement in turn impacts the functioning of many HVAC systems.
