Honeywell L604A 1177 Pressuretrol Pressure Controller 5-50PSI 250V

The Honeywell L604A 1177 is part of the Honeywell L604A Pressuretrol® Controllers series, which are used in industrial and commercial systems to regulate or limit the pressure of liquids or gases.

Key Features of the Honeywell L604A 1177:

1. Purpose:
   • Designed to control or limit the pressure in systems by operating a valve or switch when the pressure reaches a setpoint.
2. Application:
   • Commonly used in boilers, compressors, and other pressure-sensitive systems in heating, ventilation, and industrial processes.
3. Pressure Range:
   • Specific pressure ranges vary by model. For the L604A 1177, the exact range would need to be confirmed, but L604A controllers generally operate within low to medium pressure ranges.
4. Action:
   • Single-stage control (activates or deactivates at a set pressure point).
5. Adjustment:
   • Equipped with a user-adjustable pressure setpoint.
6. Switch Mechanism:
   • Includes a snap-acting switch that operates based on pressure input.
7. Housing:
   • Rugged construction to withstand industrial environments.
   • Often includes a protective cover to prevent tampering or damage.
8. Mounting:
   • Typically wall-mounted or pipe-mounted for flexibility.

Applications:

• Boilers:
  • Monitors and maintains proper operating pressure for steam or water systems.
• Compressors:
  • Ensures system pressure stays within safe operational limits.
• Industrial Process Control:
  • Regulates pressure in fluid systems for consistent performance.
• HVAC Systems:
  • Helps maintain proper pressure in heating and cooling applications.
