German ORBINOX valves ORBINOX models ORBINOX prices

The closure element (ball) of the ORBINOX valve is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. The hard-sealed V type ball valve has strong shear force between its V type ball core and the metal valve seat surfacing with hard alloy, making it particularly suitable for media containing fibers, small solid particles, etc. Multi-port ball valves can not only flexibly control the confluence, diversion, and direction switching of the medium in pipelines but also close any channel to connect the other two channels. This type of valve should generally be installed horizontally in pipelines. Ball valves are classified by actuation method into: pneumatic ball valves, electric ball valves, and manual ball valves.

ORBINOX valve industry applications

Ball valves are widely used in industries such as oil refining, long-distance pipelines, chemical engineering, papermaking, pharmaceuticals, water conservancy, electric power, municipal services, and steel production, playing a significant role in the national economy. They have a rotating action of 90 degrees, with the plug being a sphere that has a circular through-hole or passage along its axis. Ball valves are mainly used in pipelines for shut-off, distribution, and changing the flow direction of the medium. They require only a rotation of 90 degrees and minimal torque to achieve tight closure. Ball valves are most suitable for use as on/off and shut-off valves, specifically V type ball valves. In addition to paying attention to pipeline parameters, special attention should be paid to the environmental conditions when using electric valves, since the electric device in an electric valve is an electromechanical component whose operating status is greatly affected by the environment. Typically, extra care must be taken when using electric ball valves and butterfly valves in the following environments. [1]

ORBINOX valve sealing requirements

The sealing performance of a valve refers to the ability of each sealing part to prevent medium leakage, which is one of the most important technical performance indicators of a valve. There are three sealing parts in a valve: the contact area between the closure element and the two sealing surfaces of the valve seat; the fit between the packing and the valve stem and stuffing box; and the connection between the valve body and bonnet. Leakage at the first location is called internal leakage, commonly referred to as incomplete closure, which affects the valve's ability to cut off the medium. For shut-off valves, internal leakage is unacceptable. Leakage at the latter two locations is called external leakage, where the medium leaks from inside the valve to the outside. External leakage causes material loss, pollutes the environment, and may even cause accidents in severe cases. For flammable, explosive, toxic, or radioactive media, external leakage is strictly prohibited, so valves must have reliable sealing performance.

ORBINOX valve structure

Good sealing performance, but all the load of the working medium on the ball is transferred to the outlet seal ring. Therefore, consideration must be given to whether the seal ring material can withstand the working load of the ball medium. Under high-pressure impact, the ball may shift. This structure is generally used for medium- and low-pressure ball valves. Fixed-ball ball valve Fixed-ball ball valve The ball of the fixed-ball ball valve is fixed and does not move under pressure. Fixed-ball ball valves are equipped with floating valve seats. When subjected to medium pressure, the valve seat moves, pressing the seal ring tightly against the ball to ensure sealing. Bearings are usually installed on the upper and lower shafts of the ball, resulting in low operating torque, making them suitable for high-pressure and large-diameter valves. To reduce the operating torque of ball valves and increase sealing reliability, oil-sealed ball valves have been developed. Special lubricating oil is injected between the sealing surfaces to form an oil film, enhancing sealing performance while reducing operating torque, making them more suitable for high-pressure, large-diameter ball valves.
