These ERA Double Union Ball Valves are designed to accommodate our grey pressure pipe and are used in conjunction with our grey pressure pipe fittings. In a contemporary koi pond, grey pressure pipe is the only way to go. These ERA Double Union Ball Valves are very reasonably priced, significantly superior to Valterra slide valves, and will survive longer while coping with higher pressure. ERA double union ball valves provide an easy approach to separate items such as pumps, UV's, heaters, and so on.
