Point is a kind of advanced connection valve in power plant, refining, chemical plant and instrument measuring pipeline.Learn More
Screwed Needle Valve
The KOSEN Screwed Needle Valves is forged pipe connection and threaded connection. It is suitable for other gas pipelines, such as gas equipment container connection pressure gauge matching and other gas pipelines. Good sealing, long service life, even if the sealing surface is damaged, it only needs to replace the vulnerable parts, and can continue to use.Learn More
Welding Needle Valve
The KOSEN Welding Needle Valves is one of the most used valves in electric, electrical, electromechanical equipment engineering and electronic control equipment engineering. Because of its convenient installation, reasonable manufacture and simple economy, it is widely used in electric power engineering and other pipelines with beautiful appearance, good sealing performance, high pressure resistance and convenient assembly and maintenance.Learn More
Angle Type Needle Valve
The KOSEN Angle Type Needle Valves is used widely, the cutting distance for flame cutting, the knob of adjusting the flame temperature. In order to cut off the fluid. The angular pin valve has good sealing performance, so it is generally used for small flow, high pressure gas or liquid medium seal. The shape and pressure gauge are the most suitable. The angular pin type valve shape is made of screw thread. Connection. First, the anticorrosion of the valve body is mainly made of stainless steel and carbon steel.Learn More
