What is a 3-Way Twin-Pak Transfer Valve?

The HYCOA 3-Way Twin-Pak transfer valve provides simultaneous switching of two independent fluid circuits in a single manual operation. Two linked 3-way valve bodies are mechanically coupled so that both circuits change over at exactly the same moment — eliminating the possibility of operating one circuit without the other.

This is the preferred solution for applications where both the supply and return lines of a duplex filter or cooler must switch simultaneously. A single handle operation changes both circuits together, preventing cross-contamination and ensuring system integrity during change-over.

Like all HYCOA transfer valves, the Twin-Pak uses the patented resilient sealing shoe for true zero leakage and the retracting actuator for zero frictional drag on change-over. No lubricant is required. Positive mechanical lockdown holds position with no springs.
