All manual, pneumatic, hydraulic and electric butterfly valves shall be subject to pressure test and commissioning before delivery. Pressure detection is the key process to inspect the strength, sealing effect and opening and closing stability of the valve body, so as to ensure that the product can adapt to various pipe working conditions and avoid […]
In municipal water supply, building pump house and circulating water system, silencing check valve is the core pipe fitting for preventing medium backflow and protecting pump unit. HC41X and HC42X are two kinds of soft seal silencing check valves purchased frequently in the domestic water supply and drainage field. Many foreign trade customers and engineering
The foot valve is a check valve installed at the end of the pump suction pipe, usually equipped with a filter screen, which is mainly used to prevent liquid backflow in the pipeline after the pump is shut down and reduce impurities into the pump body. When the water pump starts, the foot valve opens under
Butterfly valve pressure testing is an essential step in factory quality control. It helps to verify the pressure resistance, sealing performance and overall quality of the valve before delivery.? Pressure testing helps identify potential defects, reduce the risk of leakage, and ensure that butterfly valves comply with the required specifications. It is especially important for
Double-eccentric butterfly valve is also called double-offset high-performance butterfly valve. It is an upgraded pipeline block and control valve based on the midline butterfly valve. The opening and closing friction is optimized by the two eccentric structures. It is widely used in water supply, sewage, industrial circulating water and other medium pipelines. It is also
Packing quality of outlet gate valve directly affects cargo transportation safety and customs clearance efficiency. In order to adapt to international export standards by sea and air, our gate valves are packed in a standardized export packing process, which is dust-proof, anti-collision and compliant in the whole process, so as to ensure the intact delivery
The pneumatic wafer soft seal butterfly valve is a common control valve for industrial automation pipeline, which adopts midline structure, wafer connection and pneumatic driving mode. The product supports multi-material and multi-sealing configuration, which can realize local and remote control and adapt to various industrial fluid transmission pipelines. The main structure of the valve includes
H44T-16Q Swing Check Valves are designed to prevent reverse flow in piping systems and help protect pumps and other equipment from backflow.. H44T-16Q normally uses flanged and swing disc designs. As the fluid flows forward, the disc opens under flow pressure. When fluid is stopped or reversed, the disc returns toward the seat to prevent
In various industrial pipeline systems such as water supply and drainage, petrochemical, electric power and fire fighting, medium backflow will cause pump damage, equipment shutdown, medium pollution and even safety accidents. As an automatic check valve, swing check valve is the key equipment for pipeline backflow prevention, and is often called flap check valve and
Gate valve and globe valve are the main shut-off valves in the pipeline system, which are widely used in water supply and drainage, water conservancy and industrial pipeline scenes. The two valves are mainly used for on-off control of pipeline, but there are obvious differences in opening and closing structure, operation mode, flow use and installation
Text of the article In municipal water supply and drainage, high-rise building water supply, fire fighting system, industrial circulating water, heating and ventilation pipeline and other fluid network systems, high water pressure and unstable pressure fluctuation are the core problems affecting the safety of pipeline equipment and water use stability. Excessively high pipeline pressure will
1. What Is a Centerline Soft-Seated Butterfly Valve? The centerline butterfly valve is also known as the concentric butterfly valve. The valve stem is positioned along the centerline of the valve body and disc. During operation, the disc is rotated approximately 90 degrees around the stem axis. When the valve is fully open, the disc
Recently, our team traveled to Moscow, Russia, to participate in a professional industrial exhibition and visit local customers and business partners. The trip focused on industrial valves, pipeline valves and related products, while providing an opportunity to better understand the technical requirements, product standards and practical applications of the Russian and Central Asian markets. During
In many fields such as water conservancy and water supply, industrial production and building water supply and drainage, the stable control of liquid level is the key to ensure the normal operation of the system. As an automatic liquid level control valve without external power and purely driven by machinery, the ball valve, with the
