Product Overview

The Graco 288262 Pneumatic Back Pressure Regulator is designed to maintain a stable and consistent upstream fluid pressure in circulating and spray systems. It uses air pilot pressure to control a diaphragm valve, automatically adjusting fluid flow back to the return line to keep the set pressure constant at the gun, valve, or applicator.

Key Functions

Feature Description
Pressure Control Maintains constant upstream fluid pressure regardless of flow changes.
Pneumatic Operation Air-controlled diaphragm ensures precise and repeatable regulation.
System Stability Reduces pressure spikes and pulsation in circulating lines.
Application Range Suitable for coating, finishing, and industrial fluid handling systems.

Frequently Asked Questions
