Atlas Regulating Valve 1614728500 for Air Compressor Parts

A Regulating Valve is a broad category of control valves designed to automatically manage and maintain specific process variables—such as pressure, flow rate, temperature, or liquid level—within a fluid system. Unlike simple on/off valves, regulating valves modulate the flow passage to ensure a set parameter remains constant despite fluctuations in upstream or downstream conditions. They are fundamental components for achieving stability, efficiency, and precision in industrial processes.

The primary function of a regulating valve is automatic control. The specific type of regulation depends on the valve's design and application:

• Pressure Reducing: Maintains a constant, lower downstream pressure regardless of higher, fluctuating upstream pressure.
• Pressure Sustaining / Backpressure: Maintains a constant minimum upstream pressure by restricting flow to build pressure.
• Flow Control: Maintains a constant flow rate through a line despite changing system pressures.
• Temperature Control: Modulates flow of a heating or cooling medium (e.g., steam, coolant) to maintain a set temperature.
• Differential Pressure Control: Maintains a constant pressure difference between two points in a system.

Most regulating valves operate on a simple principle of balance-of-forces:

1. Sensing: An internal mechanism (e.g., a diaphragm, piston, or bellow) senses the process variable (pressure, flow).
2. Comparison: The force generated by this sensed variable is compared against the force of a pre-set reference spring.
3. Actuation: Any imbalance between these forces causes the actuator to move.
4. Modulation: This movement adjusts the position of a plug, poppet, or globe within the valve, changing the flow area.
5. Correction: The change in flow corrects the process variable, re-establishing the force balance and stabilizing the system.

This creates a continuous, self-contained feedback loop that requires no external power, making many regulating valves self-operating.
