J61Y high-temperature and high-pressure forged needle globe valve technical parameters

The heat dissipation welding needle valve is suitable for use as an opening and closing mechanism on high pressure and high temperature pipelines such as steam in thermal power plants. The valve body material is made of high quality carbon steel, stainless steel or heat resistant alloy steel forging, and the sealing surface is made of hard alloy surfacing. The high temperature and high pressure needle valve has good sealing performance and other advantages. It is an advanced connection method valve in power stations, oil, chemical equipment and instrument measurement pipelines. When installing, the flow direction of the medium should be consistent with the direction of the arrow on the valve body. The welded needle valve can be divided into butt welding needle valve and socket welding needle valve. It is suitable for use as an opening and closing mechanism on high pressure and high temperature pipelines such as steam in thermal power plants.

Alias: butt-welded needle valve, welded needle valve, high-pressure needle valve, high-pressure and high-temperature stop valve

Working principle: When the hand wheel is rotated clockwise, the valve stem is rotated by thread, so that the needle valve core is slowly pressed against the end face of the valve seat, so that it is pressed and sealed to achieve the closing function. When the hand wheel is turned counterclockwise, the valve core slowly moves away from the valve seat to achieve the purpose of opening. Because of the welding type, the pressure can usually meet very high requirements.

Main advantages: high pressure resistance, high temperature resistance, corrosion resistance, beautiful appearance, and durable.

Scope of use: electric power industry, electromechanical engineering, chemical engineering, mechatronics engineering, shipbuilding, auto parts industry, various air sources and pneumatics, hydraulic pipelines, etc., with a wide range of uses.
