3-way valves are suitable for use in the refrigerant cycles of industrial refrigeration systems, they can be installed between pressure vessels or between pressure pipes and two safety valves. 3-way valves are activated by a handwheel. When one of the outlets closes, the other one opens forcibly. It is impossible to lock both at the same time. Maintenance-free, any defects that occur in the functional performance of the valves can be repaired.
