P8600 | Pneumatic Liquid Level Switch
BelGAS CP Control Products
The BelGAS CP P8600 is a snap-acting pneumatic liquid level switch designed for reliable level control in gas compressor scrubbers and similar applications. It uses a float-actuated mechanism to generate a pneumatic signal that opens or closes dump valves and downstream equipment based on liquid level conditions.
The float movement drives a cam and actuator assembly that modulates internal back pressure. This pressure change shifts a diaphragm and spool, switching the output signal between vented (0 PSI) and full supply pressure, delivering a clean and repeatable on/off control signal.
The P8600 is engineered for rugged field use with a simple mechanical design, making it easy to maintain, reliable in harsh environments, and ideal for protecting compressors by automatically removing accumulated liquids.
Typical Applications:
Gas compressor scrubbers, separation vessels, and general liquid level control systems

PERFORMANCE ADVANTAGES
Why the P7100 Performs Where It Counts
POSITIVE ON/OFF CONTROL
Snap-acting design provides a clear, binary pneumatic signal, ensuring dependable valve actuation without drift or ambiguity.
PROTECTS CRITICAL EQUIPMENT
Automatically controls dump valves to remove liquid from scrubbers, preventing carryover and protecting compressors from damage.
SIMPLE AND RELIABLE MECHANISM
Mechanical float and cam design minimizes complexity, reducing failure points and making the unit highly dependable in field conditions.
EASY FIELD SERVICEABILITY
Straightforward internal components and accessible design allow for quick maintenance, repair, and elastomer replacement without specialized tools.
