ORION valves can be equipped with by-passes which allow equalization of pressure on both sides of the valve. Unless otherwise specified “Built-up” by-passes will be supplied on the side of the main valve.
By-passes of other types can be made according to client request. Enquires should give complete description or drawings. By-pass valves are bolted bonnet, outside screw and yoke, socket-weld and globe valves, and materials are suitable for the same service as the main valve.
