L81 Flange Mount Pneumatic
This version of the K-Dyne, Inc. Model L81 liquid level switch incorporates a pneumatic 3-way valve, providing positive and fast system response. Its design has non-adjustable trip point and narrow level operation range making it perfect for applications where trip point tampering is unacceptable. An internal stainless steel supply gas filter reduces maintenance requirements.
