Category: K20

Proven, Wear‑Free Reliability

The K20 is engineered for long‑term performance with fully potted electronics, non‑contact position sensing, and a frictionless spool manifold validated through 2 billion cycles.

Precise, Real‑Time Control

An integrated 4–20 mA transmitter and optional end‑of‑travel sensing deliver continuous monitoring and redundant confirmation for accurate valve performance.

Fast, Intuitive Startup

Auto‑calibration, a user‑friendly interface, and a built‑in quick‑start guide enable easy commissioning and on‑site adjustments.

Flexible, Drop‑In Compatibility

A standard mounting footprint supports both single‑acting and double‑acting actuators, simplifying installation and reducing inventory complexity.

Built for Demanding Applications

Dual Intrinsically Safe / Non‑Incendive certification, a high‑visibility beacon, and industry‑leading flow capacity from 16 SCFM up to 40 SCFM ensure reliable operation in challenging environments.
