It has a robust construction that can withstand harsh operating conditions. The valve features a floating ball design in combination with the ring seat, which allows for self - alignment and excellent sealing under different pressure conditions. The body of the valve is made from high - quality materials such as carbon steel, stainless steel, or alloy steel, depending on the application requirements. The ball is precisely machined to ensure smooth rotation and accurate flow control. It can be operated manually or actuated by pneumatic, hydraulic, or electric actuators for automated control.
In the pharmaceutical industry, the Ring Type Ball Valve is used for the transfer and control of highly pure liquids and gases. Its hygienic design and tight sealing prevent contamination, ensuring the quality of the products. In the marine industry, it is used for ballast water management, fuel transfer systems, and other onboard fluid handling applications. The valve's ability to handle corrosive seawater and withstand the vibrations and shocks of the marine environment makes it a reliable choice. In the pulp and paper industry, it is used for the control of pulp slurries and process chemicals, where its wear - resistant properties and good flow control are essential.
Q: How does the floating ball design in the Ring Type Ball Valve improve its performance?
A: The floating ball design allows the ball to move slightly in response to the fluid pressure. This self - alignment feature helps to ensure that the ball makes proper contact with the ring seat, resulting in better sealing performance and reduced leakage. It also reduces the operating torque as the ball can adjust itself to the pressure conditions.
Q: Can the Ring Type Ball Valve be installed in any orientation?
A: While it can be installed in various orientations, for optimal performance, it is recommended to install the valve in a horizontal position when possible. However, it can also be installed vertically or at an angle, but care should be taken to ensure proper operation and to prevent any potential issues such as debris accumulation or improper seating of the ball.
Q: What is the difference between a flanged and a threaded connection for the Ring Type Ball Valve?
A: A flanged connection provides a more secure and leak - proof joint, especially for high - pressure and large - diameter applications. It allows for easier installation and removal of the valve. Threaded connections, on the other hand, are more suitable for smaller diameter pipes and lower pressure applications. They are quicker to install but may be more prone to leakage if not properly tightened.
MAIN FEATURES
Patented Velan ring valves are an intrinsically safe design. The ring valve has no seats. It is a throttling valve. As a result, it does not require a mechanical stop in order to avoid full closure and the resulting drum overpressurization.
Design Features
Steam purges: Steam purges to bellows and body area ensure the valve cavities are kept free of coke buildup.
Excellent throttling characteristics: In the "maximum obstruction" position, the valve provides a pressure drop equal to a butterfly valve's set at 15° open.
Automation:The electric, hydraulic or pneumatic actuator is selected in function of coker service. A large torque safety factor ensures the valve will cycle under the most stringent conditions. When selecting actuators, special attention is paid to the coker deck environment.
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.
1.One piece body
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.
2.Top entry
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.
3.Low operation torque
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.
4.Emergency sealing
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.
5.Reliable sealing
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.
6.Double block&bleed(DBB)
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.
7.Anti-static and fire safe design
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.
8.Extension stem
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.
9.Various driving types
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.
