Request Information
The Ashcroft® pressure limiting valve-PL02 is designed to protect sensitive instrumentation by limiting pressure up to a specific set value and will only open once pressure drops down below a certain value. This device is often used to mitigate pressure spikes or other momentary pressure events that can damage instruments like pressure gauges, switches and transmitters.
