● Friction-Free Operation: The ball turns only after moving away from the seat, eliminating friction and reducing wear common in traditional ball, gate, and plug valves.
● Injectable Packing: Allows for online maintenance by injecting packing into the stem through a port, effectively controlling emissions. This feature is applicable to all models with a
sealed cover.
● Single Seat Design: The rising stem ball valve's single static seat ensures zero downstream leakage and avoids the pressure
build-up issues common with double-seated designs.
● Extended Service Life: This valve can replace other valves prone to sealing failures, such as standard ball valves, gate valves, and plug valves, reducing failure rates and maintenance costs significantly.
● Optimal Flow Characteristics: Both full-bore and reduced-bore valves maintain high Cv values when open, enhancing pump efficiency and minimizing corrosion issues.
● Top Entry Design: Facilitates inline inspection and maintenance after decompressing the pipeline system, simplifying upkeep.
● Dual Stem Guides: The stem moves smoothly up and down, and rotates along guide pins, ensuring stable control.
● Self-Cleaning Feature: When the core is off the seat, the medium flows 360 degrees along the sealing surface, washing away impurities.
● Low Torque Operation: The elimination of sealing friction makes the valve easy to turn, allowing the use of a small handwheel without the need for a gearbox, except in very large
sizes.
● Wear-Resistant Hard Sealed Surfaces: The core's sealing surfaces are overlayed with hard alloy and polished, maintaining seal
integrity even under harsh conditions.
● Mechanical Wedge Seal: The inclined surface at the bottom of the stem provides a mechanical wedge force, ensuring continuous
tight contact between the core and the seat.

RAYS Through Conduit (T.C.) Slab Gate Valves are manufactured with a full bore port, rising stem OS&Y and with floating seats and gate, pressure energized, for a bubble tight shut off upstream and downstream under both low and high differential pressure. Double block and bleed capability and automatic relief of excess body pressure are a standard feature of this seat design. The smooth, continuous bore minimizes turbulence within the valve and when in the open position it produces a pressure drop equivalent to a portion of pipe of the same length and diameter. The seat faces are outside the flow stream and therefore protected from the erosive action of the flow. Pigs and scrapers can be run through the valve without damage.
Designed specifically for industrial ventilation and gas transportation systems, it features a high-strength carbon steel or stainless steel valve body, equipped with a low-torque sealing structure, enabling efficient regulation of large flow of gas media. The optimized butterfly plate design is combined with wear-resistant sealing rings, ensuring reliable performance under harsh conditions such as high temperatures and dust. It is suitable for ventilation and dust removal systems in industries such as power plants, metallurgy, and chemical engineering
Forged steel globe valve is a high-performance fluid control equipment, manufactured with high-quality forged steel materials and precision, integrating throttling and shut-off functions. Specially designed for high-pressure and high-temperature working conditions, it has the characteristics of compact structure, reliable sealing, and long service life, and is widely used in harsh working conditions in industries such as petroleum, chemical, and power.
