Welding globe valve/throttle valve JL61H-100V

【 JL61H Welding Stop/Throttle Valve Product Usage 】

JL61H welding globe/throttle valve is suitable for cutting or connecting pipeline media in various systems of petroleum, chemical, hydraulic, and thermal power plants with nominal pressures of PN200~PN320 and P54/100V-P57/170V, and operating temperatures of ≤ 540 ℃ (where P57/170V operates at 570 ℃).

JL61H Welding Globe/Throttling Valve Product Features

1. The valve cavity adopts a pressure self tightening sealing structure, which improves the sealing performance. The two ends of the branch pipe are welded structures. Welding grooves can be matched according to standards or user requirements

2. The sealing surfaces of the valve disc and valve seat are welded with Stellite cobalt based hard alloy, which is wear-resistant, high-temperature resistant, with good scratch resistance and long service life

3. The valve stem has undergone tempering and surface nitriding treatment, providing good corrosion resistance and scratch resistance.

4. The depth of the valve cover packing box is reasonable, and the packing is added with corrosion inhibitor, ensuring reliable sealing
