J23W-320P 304 Stainless Steel Needle Valve, High Temperature & High Pressure External Thread Welded Pressure Gauge Ferrule Needle Valve

Product Overview

The BKH-SAE Flange High-Pressure Ball Valve (also known as KHB-SAE) is a specialized valve designed for high-pressure fluid systems requiring flange connection. It integrates a high-pressure ball valve with a standard SAE 4-bolt flange through welding, combining the quick opening and closing characteristics of ball valves with the convenience and stability of SAE flange connection. This design is particularly suitable for occasions with vibration, impact and high sealing requirements such as construction machinery, mining equipment and hydraulic systems, making it the preferred connection solution for equipment manufacturers and system integrators.

Detailed Product Features and Advantages

1. SAE Flange: Standard and Stable

International Standards: Complies with international standards such as SAE J518 and ISO 6162, perfectly matching SAE flange ports of mainstream hydraulic components (e.g., hydraulic cylinders, hydraulic motors, valve groups) at home and abroad.
Reliable Connection: The flange mating surface adopts O-ring sealing with high sealing specific pressure, and its seismic performance is far superior to the connection method of flat flange plus gasket.
Quick Installation: Installation and disassembly can be completed quickly using flange clamps or bolts and nuts, achieving high maintenance efficiency.

2. Welded Valve Body: Integral Molding

Zero Leakage Design: The valve body and flange are welded into one piece with high strength, fundamentally eliminating leakage risks at the joint between the valve body and flange.
Compact Structure: The integrated design reduces connection points, resulting in a more compact overall structure and higher strength, which can withstand greater system impact and vibration.

3. High-Pressure Design: Safety Foundation

Reinforced Valve Body: Made of high-quality carbon steel or stainless steel through forging/casting with thickened design, ensuring safety under high pressure.
Excellent Sealing: The ball core and valve seat adopt metal hard sealing or high-performance composite materials, resistant to high-pressure erosion and having a long service life.

4. Complete Specifications: Flexible Adaptation

Offers various specifications from F3(SAE 10) to F6(SAE 25), meeting different flow requirements.
Can provide supporting standard SAE flange clamps (e.g., 420, 210 series) for one-stop procurement.
