Trunnion Ball Valve Manufacturers In India / Trunnion Mounted Ball Valves Price In India

Taking this into consideration, we offer a full range of metal to metal seated ball valves, including floating ball valves and trunnion ball valves, which are found in extensive applications such as petroleum, chemistry, power, metallurgy and light industries. Apr 10, 2020· Velan ABV decided to jump into this huge market for valves, over $500M/yr in Ball/Gate/Check, leveraging its experience with Aramco and the wide portfolio of Velan. An international Ball Valves report presents in-depth market analysis to prosper in this competitive environment. Valtorc’s trunnion mounted designed ball valves are a high strength and quality valve for your industrial needs. Metal to metal sealed design has been employed perfectly for the ball and seat, which has also adopted the advanced hardening technologies, such as ultrasonic spray coating, nickel base spray welding, surface specially hardening, satellite spray welding, ceramic material with high strength, and hardness, etc. Surface hardness of the ball and seat may generally reach more than HRC60, maximum up to HRC74, and application temperature of the material may be up to 1004°F, maximum up to 1796°F. Combining strength of the material gets to more than 1000 psi. The forging material can ensure sufficient rigidity and strength under maximum rated operation pressure.

This increase the sealing reliability while decreasing the operation torque, which is better for high pressure, big sized ball valves. To decrease the operation torque and increase sealing reliability, lubricated ball valves are adopted in recent years. A special sealant is injected between sealing faces of lubricated ball valve to create a layer. Tightness rate allowable leakage rate at full psi, ASME/FC170-2 Class V with special lapping, tighter shutoff available upon request. The seats in a high-pressure ball valve are reinforced with special seat rings that can handle the high pressure from the onstream. Carefully designed high pressure and high temperature ball valves can sustain temperatures as high as 400°F and elevated pressures up to 10,000 psi. The series 300 valves are offered in flanged connection ends with Nylon and Peek seats. Ball valves can be manufactured bar stock material, forgings, castings, with options on end connections (screwed, SW, BW, and flanged). As most of the service is not completely clean, there are maintenance options. For in-line maintenance services, the top entry ball valve can be used. The electric conductance between all the metallic components of this series Ball Valve. This can be a lever, a gear, a motor-operated gear (electric actuator), or a pneumatic/hydraulic actuator.

As the actuator is rotated, it will move the stem, which in turn will rotate the ball. When the Ball Valve body cavity pressure exceeds the down stream seat spring preloaded force, the differential force in the cavity area pushes the downstream seat away from the ball, the body cavity pressure will automatically relived. After closing the valve ball, the valve ball under the effect of medium pressure moves a little toward the valve seat, making the valve seat produce elastic deformation and exert compaction effect on valve ball, thereby ensuring the sealing of valve. For floating ball valve, the sealing force of valve seat and the sealing pressure are greatly influenced by changing medium pressure. If there is no medium pressure, the sealing force relies on elastic element that installed on the back of the seat. The fixed shaft is installed in upper and lower end of the valve ball and valve ball rotates around the axis of the fixed shaft.

The surface of the ball is perforated to help distribute the pressure evenly.

Offered in class 150/300/600/900 and 1500 in sizes from 2″ – 12″ in size. Which is suitable for widely service in valves with high pressure and big sizes. J-Flow’s design provides freedom for thermal expansion of the ball without jamming even at high temperatures. J-Flow’s single seat ball valve has a flat spring set acting through a hard face bearing against the bottom ball shaft which provides sufficient initial ball-seat load for valve tightness, even at low psi. In the Trunnion design configuration, the ball is supported by bearing plates, held in position by the valve closures.

In this case, flow is controlled by the position of a hole in the center of the ball. It contains the elements necessary for enabling or disabling the flow of fluids through the pipe. According to the material of seat, It is very important to choose appropriate-stiffness elastic elements and proper seat materials. The seat material of general purpose ball valves employ generally non-metal material, such as PTFE. And for the driving air-powered engines from forward to reverse, the function is conducted by spinning only one PP Valves. To start the flow of oil, you will move the actuator on the valve 90 degrees one way (usually clockwise). Pneumatic Actuator can be handiest to open and near the valve, or may also allow intermediate positioning; some valve actuators consist of switches or different approaches to remotely suggest the location of the valve. Limited by the seat material, the general purpose ball valve cannot be used in case of high temperature applications and applications with solid articles and ash dregs.
