The new Xomox XLB provides a universal means to manage corrosive chemicals through a cost effective lined solution, avoiding the need for expensive high alloy alternatives. The lower torque of Xomox XLB lined ball valve designs permits use of smaller actuators, allowing cost reductions and creating space saving opportunities. Our innovative "pressure assisted" SX seal device provides the highest protection from fugitive emissions. The Xomox XLB dynamic body joint design retains pressure boundary during thermal cycles.

The Xomox XLB body assembly has metal-to-metal connection that offers resistance against forces that may be created in the pipework. This feature is designed to alleviate deformation and damage to the lining, even under pressure induced stresses. Also, the body joint sealing is provided with taper lining overlap, which is especially effective under high internal pressure and temperature variations.

When valves are closed under pressure, the ball is able to float with line pressure and pressurize the downstream seat to further enhance the in-line seal. However, the stem will tend to tilt and can side load conventional packing, leading to potential wear and eventual leakage to atmosphere. The SX seal in the Xomox XLB valve moves in conjunction with the spherical portion of the stem, maintaining a constant seal to atmosphere.

In a conventional valve, moderate stem side loading can lead to significant emissions issues. Other situations where side loading can occur during valve actuation include: Heavy manual operation, actuation loads and misalignment, abusive contact. The Xomox XLB valve's pressure assisted SX seal stays in constant contact with stem spherical seal surface to significantly reduce the chance of atmospheric leakage.
