What are the causes and solutions of internal leakage in forged steel ball valves?

The causes and solutions of internal leakage in forged steel ball valves are as follows: I. Causes of Internal leakage 1. Executive agency issues: The zero position setting of the actuator is inaccurate and the valve is not completely closed. The torque force of the actuator is insufficient to overcome the driving force of the medium, resulting in the valve not closing properly. The limit error of the actuator causes the valv

What are the differences between high-platform ball valves and ordinary ball valves?

High-platform ball valves and ordinary ball valves have significant differences in structure, installation methods, performance characteristics, appearance, application scenarios and cost, as follows: Structure and installation method High-platform ball valve: It adopts a new type of ISO5211 platform structure. There is a platform on the valve stem, allowing the actuator to be directly installed without the need for a bracket. This design not only facilitates installation and disassembly, but also significantly enhances the stability between the valve and the actuator.

The design and structural characteristics of forged steel gate valves

The design and structural features of forged steel gate valves are mainly reflected in the following aspects: Design features 1. Application and medium adaptability: Forged steel gate valves are mainly used to cut off or connect the medium in pipelines. They are suitable for the working pressure range of Class150 to 2500, as well as the working temperature range of -29 to 425℃ (carbon steel) or -29 to 500℃ (stainless steel). Different materials can be selected to adapt to various media such as water, steam, oil products, acetic acid, oxidizing media, and urea.
