 Overview of Panel Mounted High - Pressure Ball Valve Products

 Panel mounted high - pressure ball valves are a type of ball valves specifically designed for high - pressure working conditions are easy to install on the panels of various devices. They have unique advantages in terms of structure, performance, application, are key fluid control components in many industrial fields.

Structural Design：The valve body is usually forged integrally to ensure high strength impact resistance, can withstand high pressure without deformation rupture. The valve stem is closely connected to the ball adopts an anti - blowout design to prevent the valve stem disengaging under high pressure ensure operation safety. The valve seat generally uses polytetrafluoroethylene (PTFE) metal materials. The former has good sealing performance a low friction coefficient, while the latter is resistant to high temperatures wear, is suitable for high - temperature, high - pressure, special medium working conditions. The ball is processed with extremely high precision, has a smooth surface, closely cooperates with the valve seat to achieve double - sided sealing, effectively reducing fluid leakage.

 Working Principle：The handle is rotated to drive the valve stem, the valve stem then drives the ball to rotate. When the through - hole of the ball is in line with the axis of the pipeline, the valve is fully open, the fluid can pass smoothly; when the ball rotates 90 degrees the through - hole is perpendicular to the pipeline, the valve is closed, cutting off the fluid. The operation is simple, a full - open full - closed action can be completed with just a 1/4 - turn, which can quickly respond to the system's on - off control requirements for the fluid.

 Product Features：

 1. Excellent Pressure Resistance：It can withstand pressures as high as several thousand psi even higher, is suitable for scenarios with strict pressure requirements such as high - pressure hydraulic systems, oil gas transportation, high - pressure test equipment.

2. Reliable Sealing：The precise cooperation between the ball the valve seat, as well as high - quality sealing materials, ensure the good sealing performance of the valve under high pressure, reduce the risk of leakage, improve the stability safety of the system.

3. Convenient Operation：The lightweight handle design results in a small operating torque, allowing the valve to be easily opened closed even under high - pressure conditions. It can be manually operated easily integrated into an automated control system.

4. Easy Installation：The panel - mounted method only requires opening holes on the equipment panel fixing it with matching installation nuts bolts, saving space facilitating centralized control maintenance.

5. Long Service Life：High - quality materials precise manufacturing processes endow it with good wear resistance corrosion resistance, enabling it to operate stably for a long time in harsh environments reducing maintenance costs replacement frequencies.

 Application Fields：

 1. Oil Gas：In the exploration, transportation, processing sectors, it is used for the cut - off control of high - pressure gases liquids, such as wellhead devices, gas pipelines, refineries.

2. Chemical Industry：Suitable for the pipeline control of various corrosive, flammable, explosive media, such as the feeding discharging of reaction kettles high - pressure synthesis processes.

4. Energy Power：Used in the cooling systems steam pipelines of nuclear power plants thermal power plants to ensure the safe transportation control of high - pressure media.

5. Scientific Research Testing：In high - pressure test equipment laboratory instruments, it is used to precisely control high - pressure fluids to meet experimental testing requirements.

 Main Parameters：

 1. Nominal Pressure：The common range is 10MPa - 100MPa (1450psi - 14500psi), there are also products with higher pressure ratings to meet different high - pressure working conditions.

2. Nominal Diameter：Generally ranging DN6 (1/4 inch) to DN100 (4 inches), the appropriate specifications can be selected according to the flow requirements.

3. Applicable Temperature：It depends on the valve body sealing materials. PTFE seals are generally suitable for - 20℃ - 200℃, metal seals can withstand higher temperatures, up to 500℃ even higher.

4. Valve Body Material：Stainless steel (such as 304, 316) alloy steel are mostly used to ensure strength corrosion resistance; for special working conditions, Hastelloy, Monel alloy, etc. can be selected.

5. Connection Method：In addition to panel mounting, common connection methods at the inlet outlet ends include threaded connections (such as NPT, BSPT) welded connections (butt - welding, socket - welding), which are convenient for connection to the pipeline system.
