The MP918A1057 model from Honeywell functions as a pneumatic high-force damper actuator, suitable for demanding automation tasks. Measuring a compact stroke length of 3.5 inches, this actuator is engineered to provide effective control in HVAC systems. The diaphragm has a diameter of 23.8 inches, allowing for substantial force and operational efficiency.
This model operates within a spring range of 8 to 13 psi, making it versatile. A notable feature is its built-in positive positioner, enhancing accuracy during operation. The actuator is designed to withstand a maximum safe pressure of 25 psi. In cases of power loss or fault, the spring return fail-safe mode ensures that the actuator reverts to a predetermined safe position, maintaining system integrity.
In terms of environmental specifications, this actuator operates at minimum temperatures down to -29 °C and can withstand a maximum temperature of 70 °C. Its design supports a relative humidity range of 5% to 95% without condensation, making it robust in varied conditions. Air connections are configured with a 5/32 inch outer diameter (OD) push-on barb for pilot applications and a 1/4 inch OD push-on barb for main air connections, promoting easy installation and integration into existing systems.
