hi everyone hope you can help
i have a y plan heating system with a sunvic duoval 3 port valve i cant find which model it is as the actuator just says duoval on the sticker it has a clear plastic window in the top with a red indicator in it the valve itself must have been leaking for quite some time so i cant see if there is a model number on it the valve is at least 17 years old could anyone please guide me to an alternative for this sorry looking valve cheers in advance
