Needle Valve

The GAIRUI 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.

The GAIRUI Stainless Steel 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.

The GAIRUI Multiport Gauge 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.

The GAIRUI Instrument 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.

The GAIRUI Stainless Steel Blow-down Valves is an important part of the instrument measuring pipeline system, mainly with cut-off valve and ball valve, its function is to open or cut off the pipeline access, the needle type valve has the convenient installation and disassembly, the needle type valve connection fasten, the needle type valve is beneficial to the fire protection, the needle type valve has high explosion proof and pressure resistance, and the needle type valve seal performance is good and so on. Point is a kind of advanced connection valve in power plant, refining, chemical plant and instrument measuring pipeline.

The GAIRUI 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.

The GAIRUI 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.
