Body It is directly connected to the pipeline (or equipment) to provide the channel of the medium circulation Bonnet To connect with the valve body (or through other parts, such as diaphragm) and it is also the main part of the pressure control with the [...]
1. ISO 9001 Quality SystemCertification The role of the certification is to establish a quality assurance system from product design to after-sales service, to monitor the quality system, so as to ensure the quality of products and satisfy users. Through the certification, to achieve the [...]
Valves are the most common equipment in heating companies, such as fully welded heating ball valves. It seems easy to install valves, but if they are not implemented in accordance with the relevant technology, that will cause a safety accident. The next is to share [...]
The application with higher requirements will put forward requirements to the shut-off valve, so the shutting off function is an important function and intrinsic quality index of the shut-off valve. Being used in a working situation, faults such as poor shutoff of the regulating valve [...]
Valve castings The valve is used on the fluid pipeline. It withstands itself the erosion and corrosion of various temperatures and pressure media. There are even small defects in the casting that can also leak, causing loss and waste of media. When transporting toxic and [...]
The working principle of the three-way ball valve is to open or close the valve by rotating the valve stem. The ball valve switch is lightweight, small in size, can be made into a large caliber, reliable sealing, simple structure, easy maintenance, the sealing surface [...]
The irreplaceability of water and the necessity of people's survival determine the importance of the safe operation of the water supply network. But due to various reasons, it’s hard to avoid the water shutdown of the local section. It is necessary to install the control valve properly [...]
In general, if it is not tightly closed, first check whether the steel valve has been closed in place. If the leak cannot be sealed after it has been closed in place, then check the sealing surface. For some ball valves, the sealing pair is [...]
The requirements for pressure test before the installation of fully welded ball valves mainly include the following aspects: Strength test The strength test uses water as the medium; after the valve is opened to the 45-degree position, water is injected into the fully welded ball [...]
Industrial valve is a device used to control the direction, pressure, and flow rate of a fluid in a fluid system. It is a device that allows the medium (liquid, gas, powder) in pipes and equipment to flow or stop, and its flow can be [...]
