High Pressure Needle Valve
The KOSEN High Pressure Needle Valves is a kind of advanced connection valve in power station, oil refining, chemical plant and instrument measuring pipeline. The needle valve has good sealing performance and long service life. Even if the sealing surface is damaged, it only needs to replace the vulnerable parts, so that it can continue to use.Learn More
Cast Steel Needle Valve
The KOSEN Cast Steel Needle Valves is a kind of valve that can be precisely adjusted. It is widely used. For example, the cutting distance of flame cutting, the knob of adjusting the flame temperature is the needle valve. Instrument needle valve is an important part of instrument measuring piping system. It mainly consists of globe valve and ball valve. Its function is to open or cut off pipeline passages. The spool of the needle valve is a very sharp cone, like the needle inserted into the valve seat.
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
The KOSEN Needle Valve Manifold is mainly divided into two valve Manifold, three valve Manifold, five valve Manifold, two Manifold of valves are two single valves together, the three groups of three single valves are combined together, the five Manifold of valves are five single valves together. The original brake system brake cavity and the lower cavity have separate air supply and exhaust circuit, the solenoid valve can realize the brake cavity air supply and the exhaust automatic switch, and the four - way valve can realize the brake cavity air supply and the manual switching of the exhaust. The solenoid valve can realize the automatic switching of the air supply and exhaust of the brake return cavity, and the four way valve can realize the brake return cavity gas supply and the exhaust manual switching.Learn More
