The valve features a welded body with a carbon-reinforced Teflon gasket, designed for frequent operation and resistance to impurities and chemicals, ensuring a long service life. A finely ground stainless steel ball guarantees reliable operation for years.
It uses a floating ball structure with an inclined plane elastic washer to maintain a tight seal against the ball, even under unstable pressure. The valve stem employs dual "O"-rings to prevent leakage, ensuring smooth rotation and eliminating the need for maintenance, adjustment, or lubrication. This design simplifies installation and reduces operating costs.
The valve stem can be extended for easy heat insulation, and the operating handle can be removed and reinstalled in reverse. The body is free of heavy castings, enhancing durability and reliability. Installing a regulator is straightforward, making the valve easy to integrate into various systems.
