The essential role of ball valves in engineering systems

Today it is difficult to imagine even a basic engineering system, whether it be water, heat, gas, air conditioning or oi transportation infrastructure without flow control devices of various media, i.e. without the pipeline valves. The principle of operation of any pipeline valves is based on the change in the flow cross sections. One of the most common type that is used to shut off the flow of the medium is the ball valve. The devices invented almost 100 years ago rely on basic physics laws and no significantly more effective alternative until nowadays.

Ball valves and durable industrial ball valves by Orseal, a seasoned engineering equipment manufacturer, are a decent example of a finest quality and unsurpassed cost-efficiency: by its parameters, they in no way inferior, and in many ways superior to costly analogs by large US and Swiss enterprises. Orseal focuses on reliability and durability and promotes easy-to-use systems, valves for gas, water, heating and cooling, as well as for other industrial processes.

When choosing body ball valves for common industries considering carbon steels and special heat-resistant colored enamel models that can withstand operating temperatures up to 200°C, and having a high resistance to the appearance of scratches. However, it is worth noting that there are models of valves providing heat and cold-resistant performance that can withstand ambient temperatures up to -60 ° C, which is especially important for the northern regions, oil and gas industries. Since the locking sphere is the most crucial element in the construction, it is typically made of stainless steel. Additionally, the ball is covered with grease, thus reducing friction and wear of ring seals, plus it increases the life of the ball itself. The surface of the ball is carefully polished with protecting layer (but no more than 0.1 micron thickness). Such a high accuracy at times allows to reduce the wear of ring seal, and hence to considerably increase the service life of the tap (when compared to conventional valves). The reliability and durability of the saddle seal is provided by the crane, which is made of a fluoroplastic with the addition of 20% carbon. In connection with this increase, the design life with proper maintenance grows up to 25 years. The production range of steel ball valves typically includes 16, 25, 40 bar models in a range of diameters from 15 to 500 mm. There are the following options for configuration management you may want to make use of: mechanical gearbox, manual (stick), electric actuator, pneumatic actuator.

To press for an increased durability pay attention to A-class integrity throughout life, through the use of disc springs, which create additional seat springing. Every ball valve is tested for strength and density of design with water or air – saddle seals for leaks, after which it is assigned to a unique number. Ball valves Biwa, successfully passed the test, go to the packing area where passport-equipped with detailed instructions and labeling.
