The J-VALVES DN700 PN10 WCB flanged gate valve has become an ideal valve to meet the needs of multiple industries by virtue of its outstanding features. I. Reliable Material - WCB Carbon SteelThe select

In the current complex industrial and living scenarios, valves play a vital role in fluid control. J-VALVES stainless steel trunnion ball valves stand out among numerous industries by virtue of their unique product features and wide adaptability, and have won the praise of being "all-round valves".

In modern industrial production, fluid control is a key link to ensure the smooth progress of the production process. As an efficient and reliable fluid control device, the ear shaft ball valve is widely used in multiple fields such as petroleum, chemical engineering, natural gas and water treatment

Stainless steel high-pressure ball valves with high-pressure design and excellent sealing performance are specially designed for high-pressure environments. They can withstand extremely high pressure while maintaining excellent sealing performance. The sealing surface adopts an advanced hardened sur

Structural characteristics of trunnion ball valves. (I) Trunnion support design. The core structure of a trunnion ball valve is the trunnion support system. The ball is fixed by trunnions at the top and bottom. This design significantly reduces the friction between the ball and the valve seat, and a

Structure and working principle of floating ball valveThe core component of a floating ball valve is a floating ball. Under the action of medium pressure, the ball can produce a certain displacement and be tightly pressed against the sealing surface at the outlet end, thereby realizing sealing. This

Sealing principle of elastic gate valveThe core component of the elastic gate valve is the elastic gate. Its sealing principle is based on the elastic deformation compensation mechanism. The following are the key points of its sealing principle: I. Elastic deformation compensation The elastic gate i

I. Basic Characteristics of Floating Ball Valve(1) Structural PrincipleThe core component of the floating ball valve is a ball that can freely float within the valve body. The outer surface of the ball is machined with a sealing surface, which closely cooperates with the valve seat to achieve sealin

Application Practice of Low-temperature Trunnion Ball Valves in the LNG Field(1) LNG Receiving TerminalThe LNG receiving terminal is an important link in the liquefied natural gas industry chain, responsible for receiving, storing, and transshipping LNG. In the receiving terminal, low-temperature tr

Structural Design of Trunnion Ball Valve(1) Trunnion Support StructureDesign Principle· The core design of the trunnion ball valve is to fix the ball in the valve body through the trunnion, and the ball will not move towards the valve seat during the operation. This design significantly reduces the

Water treatment is an important link to ensure the sustainable utilization of water resources and environmental protection. In water treatment systems, valves, as key fluid control components, directly affect the operational efficiency and stability of the system. Floating ball valves have been wide

I. Basic Principle and Structure of Floating Ball ValveThe core component of a floating ball valve is a ball with a passage. Under the action of medium pressure, the ball can freely float between the valve seats. When the valve is opened, the passage of the ball aligns with the pipeline, allowing th

The pneumatic butt welded ball valve is a type of valve that controls the on-off of the fluid by driving the rotation of the ball through a pneumatic actuator. It has the advantages of rapid opening and closing, good sealing performance and convenient operation, and is suitable for various industria

I. Corrosion Resistance: A Reliable Guarantee in the Marine EnvironmentMarine engineering equipment is exposed to a high-salinity and high-humidity environment for a long time, and the corrosion problem has always been a key factor affecting the equipment's lifespan and safety. The corrosion resista

Selection Guide(1) Selection Based on Fluid CharacteristicsLiquid: If the fluid is water or a low-viscosity liquid with few impurities, a Y-type strainer can be selected; if the fluid is oil or contains a large amount of impurities, it is recommended to choose a basket strainer.Gas: For gas filtrati

STRUCTURAL DESIGN: It may adopt a swing-type structure, where the valve disc is connected to the valve body through a hinge mechanism and can rotate around an axis to open and close. This structure is relatively common in large-diameter valves. It enables the valve disc to have sufficient swing space when opening, and the fluid encounters relatively low resistance when passing through. It may also be a lift-type structure, where the valve disc slides along the vertical centerline of the valve body and opens and closes relying on the pressure of the medium. This type has better sealing performance.

In modern industrial production and various fluid transmission systems, valves play a crucial role in the precise regulation of flow. As commonly used fluid control equipment, the gate valves and globe valves of the J-VALVES brand exhibit different flow regulation capabilities in terms of opening co
