Can I replace this zone valve with this Uponor zone valve?

    That is a Stadler manifold. Stadler was bought out by Viega. Viega thermal actuators with an adapter is the replacement for a failed Stadler actuator. There is a brochure on Viega's website on how to replace Stadler's actuators.

    Does Uponor work??? Call Uponor tech support.
