Forged steel fixed ball valves: Low pressure forged steel fixed ball valves, high pressure forged steel fixed ball valves.
The three-body connection forged steel fixed ball valve divides the body into three parts along the cross section perpendicular to the axis of the valve passage at the two seat positions. The whole high-pressure forged steel fixed ball valve is symmetrical along the central axis of the valve stem. It is mainly used to cut off, distribute and change the direction of medium flow in the pipeline. Its large pivot structure ensures accurate ball center position under high pressure and good operation performance of the valve; the standard valve seat adopts spring structure to push the valve seat to the ball, which ensures good two-way sealing performance for inlet and outlet; the valve body cavity can be discharged outward by using the self-contained discharge valve; the pivot adopts blowout-proof protection. The structure effectively prevents leakage; the bearing with low friction coefficient reduces the torque to small, facilitates the opening and closing of the valve; the effective contact between the valve stem and the valve body makes the anti-static grounding device superior in performance, etc. It has the advantages of excellent performance, high reliability, wide use and reasonable price.

By using the self-contained discharge valve, the body cavity can be discharged outward. Forged steel fixed ball valve pivot adopts blowout-proof protection structure, low friction coefficient bearings, etc. It has excellent performance, high reliability and wide application.
Related Designs of Forged Steel Fixed Ball Valve
Ball of forged steel fixed ball valve is fixed, it does not move with medium pressure. Forged steel fixed ball valve has floating seats. The seats move with the medium pressure to tight the ball and seal ring to ensure sealing reliability. Bearings could be mounted in top shaft and bottom shaft, which reduces operation torque. This is widely used in valves with high pressure and big sizes. 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. This increase the sealing reliability while decreasing the operation torque, which is better for high pressure, big sized ball valves.
Sealant injection device
Trunnion mounted ball valves are provided with devices for sealant injection, which are on both the stem and seat for the forged steel fixed ball valves of dn>150mm (nps6), and in the body cavity for the valve of dn<125mm. When the o ring of stem or the body seat ring is damaged due to accident, the medium leakage between body and stem can be prevented by injecting the sealant through the device.
Double block and bleed
Forged steel fixed ball valve features the front ball sealing design structure. Each seat of the ball valve can separately cut off the medium at both upstream and downstream to achieve double block function. When the ball valve is closed, body cavity is segregated from both upstream and downstream even there is pressure at both ends. The medium left in the body cavity could increase the pressure to propel the seats. The medium could be bled out through the relief valve to ensure valve safety.
Anti-static design
Except for the anti-static features floating ball valve has, the forged steel fixed ball valve has more. The ball of the forged steel fixed ball valve gets close contact with each other through the trunnion, adjusting cushion, and down-end cap, the passage of static electricity thus forms together with the valve, which may lead the static electricity caused by sparks generated by friction between the ball and seat during on and off performance to the ground to prevent the possible risk of fire or explosion.
Fire safe design
With the valve heated in a fire application, the nonmetal material parts such as seat sealing ring of ptfe,o ring for the stem, and sealing gasket for body and bonnet, might be damaged due to high temperature. Crv's special design of auxiliary metal to metal or the graphite seal is designed for the forged steel fixed ball valve to effectively prevent both internal and external leakage of the valve in case of fire.
If forged steel fixed ball valves in the original system are heavily maintained, the sealing performance of the stuffing boxes as well as the parts such as joints are supposed to be checked carefully. In order to make sure that forged steel fixed ball valves can be operated normally and the pipeline system can run smoothly, whether the information on the data plates of forged steel fixed ball valves is in consistent with the design requirements should be checked first before the new forged steel fixed ball valves are operated and installed.
Besides these, the following aspects of forged steel fixed ball valves are also supposed to be paid attention to.
The pipelines connected with two ends of forged steel fixed ball valves are supposed to be prepared well, and be made concentric. Two flange sealing surfaces should be parallel. Pipelines should bear the weight of the ball valve, or else appropriate support devices must be equipped on the pipelines. Blow and clean the pipelines connected with two ends of the forged steel fixed ball valve. Remove the oil contamination, welding slag and all other impurities inside pipelines. Check the marks of ball valves, and whether the ball valve is intact. Opening and closing the ball valves for several times to make sure they work normally.
Remove protectors on the flanges which connect both ends of ball valves. Check the potential dirt probably left in the valve opening and then clean the valve opening. Even just little particles between valve seats and balls may damage the sealing surface of valve seats. Install the forged steel valve on the pipeline, and both ends of the valve can be installed on the upstream end. Valves driven by the hand shank can be installed on any position of pipelines. But ball valves with gearboxes or pneumatic actuators should be installed straight, that is, being installed on horizontal pipelines, and driving device should be installed above pipelines.
According to the design requirements of pipelines, it is demanded to install gaskets between valve flange and pipeline flange. Bolts on the flange need to be symmetrically, successively and evenly tightened. Open and close the ball valves for several times to check whether the ball valves can be operated flexibly, smoothly and normally. According to the design requirements of pipelines, check the sealing performance of flange joint face between pipelines and ball valves.
