Indicator Ports

Cook indicator ports provide convenient access for monitoring cylinder pressure.

Regular diagnostic testing is key to extending compressor runtimes and avoiding unplanned downtime. Many compressors, however, are not manufactured with indicator ports to allow pressure monitoring. While adding a tapped indicator port requires cylinder disassembly, machining and hydrotesting – introducing cost, downtime and risk of damage to the cylinder – Cook indicator ports provide safe, easy access.

Non-invasive, Secure Access for Pressure Monitoring

A Cook indicator port valve provides access to cylinder pressure using a connection that passes through the center of a valve and extends out the cylinder. An indicator valve mounted on the end of the indicator port allows pressure readings to be taken manually, using a pressure transducer, or automatically, using an online monitoring system.

Cook indicator ports are designed to fit existing compressor valve ports, eliminating the need to machine or modify the cylinder. They can be included with any new MOPPET®, Manley® or Optima™ series compressor valves, or retrofitted to existing valves as part of upgrade projects. They can be applied to either suction or discharge valves.

Cook indicator ports are also compatible with most valve restraint designs. If the existing restraint includes a jack bolt, however, Cook Compression will upgrade it to an HSR design that replaces the jack bolt with a multi-stud design for stronger retention.
