Main Control Valve: The primary function of the main control valve is to actively manage and regulate the flow rate or pressure of fluid within the system. It is responsible for controlling the desired system operation, such as adjusting fluid flow to a specific level.
Relief Valve: In contrast, the relief valve is a safety device that activates only when system pressure exceeds a pre-set limit. Its sole purpose is to protect the system from overpressure conditions.
Operation:
Main Control Valve: This valve is operated manually by a user or automatically by a control system to achieve specific tasks. It allows for fine-tuning and control over flow rates, pressure, or other system parameters.
Relief Valve: A relief valve operates passively, remaining closed during normal operating conditions. It automatically opens when system pressure becomes excessive, facilitating the escape of surplus fluid and restoring the system to a safe pressure level.
Setting and Adjustment:
Main Control Valve: Users or automated control systems can adjust the main control valve to fine-tune system parameters within defined operational ranges.
Relief Valve: Relief valves are typically pre-set to open at a specific pressure limit, determined based on system requirements and safety standards. They are not meant to be actively adjusted during normal operation.
Placement in the System:
Main Control Valve: Positioned within the system to actively manage fluid flow or pressure, typically closer to the points where fluid is utilized or distributed.
Relief Valve: The relief valve is strategically located downstream of the main control valve and closer to the system's pressure source. It serves as a protective barrier to prevent overpressure situations and safeguard the system's integrity.
