Gate valves are bi-directional valves ideally suited for on-off duties OMB produces various types, with parallel face gates or wedge gates (as closure elements. These valves have a high flow coefficient (Cv), and in the case of parallel gate valves, it is comparable with the straight pipe's Cv. They are usually installed in high pressure fluids applications because the upstream pressure helps the sealing between gate and seat. OMB is continuously studying and improving the surface finish of the seating in order to guarantee the minimum wear under high pressure conditions. Gate valves are supplied in various models that cover a wide range of different and unique services.

Globe valves are unidirectional and closing-down valves in which the closure member is moved squarely on and off the seat and are designed to maintain the pressure flowing under the disc. In this way, the opening of the port is directly proportional to the travel of the disc. This proportional relationship is ideally suited for applications that require flowrate regulation. In order to increase precision in the regulation, the disc element is available in three different configurations: parabolic, needle and v-port. Furthermore the short-travel of the disc between the open and closed positions makes these valves ideally suited for on-off duties when they must be opened and closed frequently.
