Introduction to Stainless Steel External Thread Needle Valve

Instrument needle valve is an important component of instrument measurement pipeline system, mainly including globe valve and ball valve, which is used to open or cut off pipeline passage.

Needle valve driving devices can be divided into manual devices, gear transmission devices, pneumatic devices, electric devices, hydraulic devices, gas-liquid linkage devices, electro-hydraulic linkage devices, etc. according to the power source. The primitive and simple valve driving device is a handwheel and handle. With the increasing size of needle valves and the automation of production processes, there is a growing demand for various needle valve drive devices.

General valve flange connection steel globe valve and lift check valve

Widely used, such as the cutting torch for flame cutting, and the temperature adjustment knob is a needle valve. Instrument needle valve is an important component of instrument measurement pipeline system, mainly including globe valve and ball valve, which functions to open or cut off pipeline passage. The valve core of a needle valve is a very pointed cone, and the sealing of a needle valve is achieved by inserting the cone into the valve seat to achieve a good sealing effect.

Based on the stainless steel needle valve structure, it is a newly designed and widely used valve of the new generation.

The anti-corrosion of the valve body of stainless steel external thread needle valve mainly depends on the correct selection of materials.

Stainless steel instrument needle valves are suitable for media such as liquefied petroleum gas, water, acid, steam, oil, etc. J49H/J49W3-6mm 1.6-32MPa J61Y Needle Valve Model Diameter Pressure J61Y-1.6/32P Welded Needle Valve Applicable media: liquefied petroleum gas, water, acid, steam, oil products, etc.
