What is the difference in price between the check valve HH48X-10C and the HH49X-10C?
The price will not be too much difference, the appearance looks the same. It's just a little different from the inside structure.
Since this model has exceeded the standard requirements, so there is no uniform manufacturers. There are dozen HH49X, there are also playing HH48X, HH49X, in fact, are the same kind of valve.
HH47X, HH48X and HH49X are all the same, all of which are micro blocking, slow closing and butterfly type silencing check valves.
