The Ring Type Ball Valve series is engineered with high-quality materials to ensure long-term durability and consistent performance under extreme conditions. Its design minimizes flow resistance, enabling efficient fluid transfer while maintaining a reliable seal under high pressure and temperature fluctuations. Available in various sizes, pressure ratings, and seat materials, these valves can be customized to suit diverse industrial requirements. With flexible end connections including flanged, socket-weld, and butt-weld options, integration into existing piping systems is simple. The valve can also be fitted with electric, hydraulic, or pneumatic actuators, making it ideal for automated operations in demanding coker service applications.
Ring Type Ball Valves and Backpressure Coker Ball Valves are widely used in industries that require reliable sealing, wear resistance, and accurate flow control:
Mining Industry – Handles slurry and wastewater with excellent resistance to abrasion and solids.
Petrochemical and Refining Plants – Used as Coker Ball Valves for safe and efficient backpressure control under severe operating conditions.
HVAC Systems – Provides precise regulation of chilled water and hot water, improving energy efficiency.
Food & Beverage Processing – Soft-seated Ring Type Ball Valves ensure hygienic handling of milk, juice, sauces, and other liquid products.
Water & Wastewater Treatment – Reliable in flow diversion, distribution, and slurry applications with high solids content.
For applications requiring on-line maintenance, the Top Entry Ball Valve design allows servicing without pipeline removal, reducing downtime and simplifying operation in critical systems.
The patented Velan Ring Valves feature an intrinsically safe design with no seats, functioning as throttling valves. This unique construction eliminates the need for a mechanical stop, preventing full closure and reducing the risk of drum overpressurization.
Steam Purges – Integrated steam purges to the bellows and body cavity keep the Ring Valves free from coke buildup, ensuring smooth and reliable operation.
Throttling Performance – Provides excellent throttling characteristics; in the “maximum obstruction” position, the valve achieves a pressure drop equivalent to a butterfly valve at 15° open.
Automation Options – Compatible with electric, hydraulic, or pneumatic actuators. Each Coker Ball Valve is designed with a large torque safety factor to guarantee reliable cycling under the toughest coker service conditions. Special attention is given to actuator selection to meet harsh coker deck environments.
Top entry ball valve is mainly used in pipeline and industry system and it has a top entry and on line maintenance function. It has a lot of advantages, such as small fluid resistance,simple structure, small volume, light weight, reliable saaling, convenience for operation and maintenance, open and close quickly, as well as start and close flexibly.
One piece body is used for the body to guarantee sufficient strength and rigidity under maximum rated operating pressure. The internal parts of valve are carefully designed and selected to ensure reliability under all kinds of operating condition. Enough margin wall thckness and adaptation of high strength connective bolts are convenient for valve maitenance and sufficiency to support the stress from piping.
Its most difference from common ball valve is that its maintenance can be made on pipe line and without dismounting from the pipe line. The back space seat structure is adopted for the seat and the rear portion of seat retainer is oblique angle to prevent accumulation of impurity from affecting back space of seat.
Top entry series ball valve has a trunnion mounted ball, whose surface is ground, polished and hard face treated. The ball and stem is integrated, sliding bearing is installed on the external bore so that the friction radius is small and operation torque is very low.
Compound injection holes are designed and compound injection valves are installed at locations of stem/cap and body support of side valve. When sealing of stem or seat is damaged to induce leakage, the compound can be used to do the second time sealing. A concealed check valve is installed in side of each compound injection valve to prevent compound from out flowing due to the action of transmitter substance. The top of the compound injection valve is the connector for fast connection with compound injection gun.
The seat sealing is formed by seat sealing and metal retainer component. The seat retainer floats axially and low pressure sealing of valve seat is reached by pre-pressure of spring. In addition, the piston effect of valve seat is designed reasonably, which realized high pressure sealing by the pressure of operating medium and realize the interception of retainer to form the sealing of the body. The expansion graphite ring is designed to realize sealing under fire condition.
When ball is full open or close position, the transmitter substance in center cavity of body can be released by drainage and emptying devices. In addition, the over loaded pressure in the center cavity of valve can be released to low pressure end by self relief seat.
The fire prevention design of valve meets the requirement in API6FA/API607 standard and the design of the anti-static conforms to regulations in API6D and BS5351.
For the underground installed valve, the stem can be lengthened and for the convenience of operation the corresponding compound injection nozzle and drainage valve can be extended to the top of valve.
The top pad of valve designed according to ISO 5211, which is convenient for connection and exchange of various drivers. The common driving types are manual, electrical, pneumatic and pneumatic/hydraulic.

A: The selection of the seat material depends on several factors such as the type of fluid (corrosive, abrasive, or clean), the operating temperature, and the pressure. For corrosive fluids, a soft - seat made of a chemically resistant polymer like PTFE may be suitable. For high - temperature and high - pressure applications, a metal - to - metal seat would be a better choice.
A: The lifespan of the valve depends on various factors such as the operating conditions, the frequency of operation, and the quality of maintenance. Under normal operating conditions and with proper maintenance, a Ring Type Ball Valve can last for many years. However, in harsh environments or with frequent operation, the valve may need to be replaced or serviced more frequently.
A: Yes, the Ring Type Ball Valve can be used for gas applications. Depending on the gas properties and the operating conditions, the appropriate seat material and valve construction should be selected to ensure safe and reliable operation. For example, metal - to - metal seats may be preferred for high - pressure gas applications.
A: Yes, Ring Type Ball Valves are designed for durability and can withstand frequent cycling without significant wear. Since they do not rely on traditional soft seats, they are less prone to seat degradation, making them ideal for high-cycle applications such as in coking units or refining processes.
A: Regular inspection and preventive maintenance are recommended. This includes checking for leakage, ensuring that the actuator (manual, electric, or pneumatic) is functioning properly, and cleaning any deposits that may affect performance. For critical service, scheduling periodic professional servicing can significantly extend the valve’s operational life.
