INTRODUCING THE LF311...
The LF311 is a single-stage piston-sensed pressure regulator for applications that require higher supply pressures in addition to an extended life cycle.

Based on the LF301, the LF311 also offers a ‘solid disk’ seat design which is more robust for aggressive or high temperature applications.

PLEASE CONTACT THE PRESSURE TECH OFFICE IF YOUR ORDER REQUIRES ANY SPECIAL MODIFICATIONS OR REQUIREMENTS.

APPLICATIONS:
• Gas cylinder regulator assemblies
• Pressure test rigs
• Instrument air lines
• Aircraft service carts

FEATURES:
• Piston sensing element
• Lightweight and compact design
• 316SS threaded bonnet
