Overview

The FK 80 is part of the 2/2‑way coaxial direct acting valve family from müller co‑ax / Co‑Ax Valves, designed to provide dependable flow control in demanding industrial environments. These valves are solenoid actuated, hermetically sealed, and pressure‑balanced, enabling them to control fluids from low to moderate pressures without leakage even if internal seals are worn. The FK 80 model specifically offers high flow capacity with a Kv value of 92.0 m³/h, making it suitable for applications requiring significant throughput. Typical features include stable switching performance, compatibility with a broad spectrum of media, and flexible electrical actuation options. Its rugged build with an IP65 protection class and industrial‑grade insulation rating ensures durability and continuous duty capability. The valve design can be adapted to match specific material, sealing, and application demands.
