Ball Valves are a manually operated control valve that requires the handle to be turned 90 degrees to open and close. Ball Valves are widely used for Burning Bar and Lance Pipe holders. Many people do not realize that standard ball valves you buy off the shelf are not safe for use with Oxygen. As a matter of fact there are very few ball valves that are manufactured and assembled Oxygen Safe or Oxygen Cleaned
Oxylance Ball Valves have three major differences to most Ball Valves. Most common ball valves have a single Teflon seal around the stem. The stem goes into the valve body from the outside and the stem has a nut that holds it in place. This nut also puts the sealing pressure on the Teflon seal. Then the handle is attached to the stem with a second nut. These nuts tend to loosen up over time and oxygen can leak from the stem.
The Oxylance Ball Valve has a stem that is inserted from the inside of the body and has three seals. One Teflon that seals the face of the stem and two Viton O-rings on the stem shaft. The other difference is the body of our ball valves are CNC machined with tight tolerances so they last for many years. Lastly, our ball valves can be rebuilt and we stock all of the parts necessary to rebuild them.
Lever Valves have a spring loaded lever handle that has to be manually operated to open and close. Lever valves give the operator the ability to vary the oxygen flow according to the volume required. Lever Valves are used primarily for Lance Pipe applications where the operator has to stand back and have variable control of the oxygen flow. Our precision lever valve was designed to have a safe operating range up to 200 psi. We do not use a rubber plunger on the Valve Stem as the rubber can deform and is only rated for 100 psi operating pressure. Our stem and plunger is CNC machined out of brass and the seal for the plunder and the stem are both Viton Rubber O-rings. This allows the valve to operate at higher pressures without deforming the plunger.
