Relief Valves
A pressure relief device that opens automatically when system pressure rises above a safe level, venting the excess to protect the equipment downstream.
Why it matters
Protects instruments, sample cylinders, and operators from overpressure events, reducing the risk of equipment damage, lost samples, and unplanned downtime.

Product features
- Automatic overpressure protection for sampling and pipeline systems
- Reseals once system pressure returns to its normal operating range
- Helps protect gauges, analysers, regulators, and sample cylinders
- Suited to instrument, analyser, and sample handling installations
- Selected to suit the pressure, temperature, and media of the application
