The rocker-shaped gland bridge compensates for uneven adjustments of gland nuts, ensuring smooth operation even when misalignments occur. Additionally, the extended neck design provides ample room for up to two inches of pipeline insulation, which is essential in maintaining thermal efficiency and protecting the system from external conditions.
The body of the valve features a flattened bore at the shaft journal ports, which positions the shaft bearings close to the disc. This design provides superior shaft support, minimizing wear and extending the lifespan of the valve. Another innovative feature is the tangential positioning of the disc taper pins, with half embedded in the disc and half in the shaft. By placing the pins in compression rather than shear, the potential for failure is significantly reduced, increasing the reliability of the valve.
An integrally cast disc position stop ensures that the disc is perfectly located within the seat, optimizing seat and seal life. Furthermore, the valve is equipped with seats made from various materials, allowing for extended service life across different applications. This versatility ensures that the valve can be tailored to suit specific operational needs, making it a robust solution for demanding environments.
