“This is identical to the valve that was installed in my house 45 years ago. After a heating zone had not been used for years, the valve was seized up. I tried to purchase just the replaceable insert parts and they actually cost substantially more than buying the whole valve. So I bought the whole thing and will move the replacement parts to the old valve. Call this a buying tip. The valve looks great, but it has not yet been installed. Will wait for warm weather.”
