When the O ring of stem or the body seat ring is damaged due to accident, the medium leakage between body and stem can be prevented by injecting the sealing grease through the device.

Flow dynamic studies were performed in a mechanical pulse duplicator with Starr-Edwards ball valves. It was shown that the "effective orifice" of the ball valve is less than the measured orifice of the cage of the ball valve. The orifice is decreased to 83 per cent of the measured orifice in the smaller and to 89 per cent in the larger valves. These measurements corresponded well with the measurements of the "effective orifice" of the valve implanted in patients who were examined by left and right heart catheterization and left ventricular angiocardiograms several months after placement of the valve.

The Model 6120 ball valve prosthesis introduced in 1965 is still strongly supported as a mitral valve substitute in many centers around the world. A current reassessment of the performance of this prosthesis is therefore pertinent to current medical practice.Longevity and durability due to the use of brass ball plated with polished chrome plated (Warranty life 4000 cycles) and increased brass ball valve thickness of the crane and weighted design Corrosion resistance due to high-quality materials crane parts that are not subject to corrosion and provide maximum protection for the crane.The ball valves were later found to contain as much as 18 percent lead by weight on inner surfaces in contact with drinking water.

These portable generators are less expensive and could be brought to any remote portable generator areas. They are smaller when compared to standby generators that only cranes or forklifts can afford to carry. Many opt for portable generators especially to those who are having businesses to run. It is really a necessity to them to have a standby generator sets. Carbon Monoxide poisoning is one of the risks of having a portable generator set.
