High-Flow Pilot-Operated Pressure Regulators - R119 Series

Brand: Parker Hannifin

Parker's R119 Pilot Operated Regulators are heavy duty, rugged regulators that provide accurate pressure regulation and very quick response times and is ideally suited to handle the most demanding industrial applications. 

This pilot operated regulator can be controlled by a remote or distant small pilot regulator and is ideal for maximum capacity requirements in applications where units are not readily accessible. 

The R119 also has high flow performance and is great fit for those installations calling for constant pressure with wide variation in flow. 

With a diaphragm operated design, balanced poppet and constant bleed pilot, this regulator has quick and accurate regulation. 

For specific flow and space restricted applications, this product can provide a solution that does not sacrifice performance. With various options available, R119 regulators can be easily configured for your application.
