Technical Specifications of DBB BALL VALVESDouble block and bleed ball valve Body Material: Forging is selected. It has excellent mechanical properties, high strength and good toughness, can withstand high pressure, ensuring the reliability and stability of the valve body, preventing deformation and

The operational principle of the double block and bleed ball valve (DBB ball valve) unfolds as follows:When in the closed configuration, the ball snugly mates with the valve seat, thereby generating the initial sealing barricade. This barricade functions with great efficacy in impeding the onward pr

The performance of wedge gate valves can be affected by changes in temperature and pressure. Here's how:Temperature ChangesSealing and Wedging Issues: In high-temperature environments, the material strength of the valve components may decrease, and the hardness of the sealing surfaces may reduce. Th

The disadvantages of wedge gate valves are as follows:High operating torque:Due to the wedge shaped structure, when opening and closing, the gate has to overcome significant friction and medium pressure. As a result, a relatively high operating torque is needed. This may make manual operation more d

Compared with other types of gate valves, wedge gate valves have the following advantages and disadvantages:AdvantagesGood sealing performance: The sealing surface is wedge-shaped with respect to the vertical centerline. When closing, the gate can be "wedged" into the valve body, forming a tight sea

On this special Christmas, the J-VALVES team got together with joy and friendship. We exchanged carefully selected gifts, and each package was filled with anticipation and kindness. When opening the gifts, laughter filled the air, revealing the thoughtfulness within. These simple acts of giving not only strengthened the bond between us but also reminded us of the importance of sharing and caring during this festive season. It was a heartwarming moment that we will remember as we move forward, united and ready to face the challenges of the new year.

Product Overview High Visibility and Easy Identification: The red gate valve has extremely high visibility in the pipeline system. Especially in complex industrial environments or emergency situations like the fire-fighting system, operators can quickly locate and accurately operate it, saving time and improving the emergency response speed.

In numerous industrial and civil pipeline systems, threaded ball valves play an extremely crucial role. The design of threaded ball valves is highly ingenious. The core components, the ball and the valve seat, fit closely together. The circular through-hole on the ball can precisely control the flow and direction of the fluid. When the ball rotates 90 degrees, the pipeline can be fully opened or closed, and the operation is extremely convenient. The connection method adopts a threaded design, which not only makes the installation process simple and efficient, requiring no complicated tools and professional techniques, but also enables easy disassembly and repair, significantly reducing maintenance costs and time.

In today's complex and diverse industrial and civil pipeline systems, precise control and efficient sealing of fluids are of utmost importance, and the self-sealing gate valve is undoubtedly one of the best.The self-sealing gate valve, with its unique structural design, exhibits excellent sealing peNamephoto introduction photo introduction photo introduction photo introduction photo introduction photo introduction photo introduction photo introduction photo introduction photo introduction photo introduction photo introduction photo introduction photo introduction photo introduction photo intro

The Y-Type Globe Valve is a core component in industrial piping systems. Its unique Y-shaped structure significantly reduces flow resistance, enabling efficient and energy-saving fluid transportation. The exquisite sealing technology ensures a tight fit between the valve seat and the valve disc, capable of withstanding high pressure and eliminating leakage, effectively guaranteeing the safe and stable operation of the system. With a simple design and excellent performance, it precisely regulates the flow rate to meet the requirements of different working conditions, providing reliable support for your engineering projects.
