Socket Weld Globe Valve

Socket welding globe valve is a stop valve that is directly connected to the pipeline through the welding end (socket interface). It uses the valve disc to achieve medium cutoff by linear motion. It is designed for high pressure, high temperature and harsh working conditions.

Features
Compact structure: The socket welding stop valve has a compact design and occupies a small space, which is suitable for installation and use in limited space.
Good sealing performance: The sealing surface of the valve is not easy to wear and scratch, ensuring good sealing performance. ⁠⁣
Flexible opening and closing: The opening and closing operation of the socket welding stop valve is flexible, the valve disc stroke is small, and the opening and closing time is short. ⁠⁣
Easy to manufacture and maintain: The structure of this valve is simple, easy to manufacture and maintain.
Wide range of application: The socket welding stop valve is suitable for a variety of media, such as water, oil, steam, etc., and can work under different temperature and pressure conditions.
High strength and corrosion resistance: The key components are made of forged steel materials, which have high strength and excellent corrosion resistance, and can operate stably for a long time under harsh working conditions. ⁠⁣
Multiple bonnet designs: There are three bonnet designs for socket welding stop valves, including bolt connection, spiral wound gasket sealing bonnet, nut connection, fully welded sealing bonnet and threaded connection internal pressure self-tightening bonnet.

Design standard: Follow API 602 (forged valve) and ASME B16.34 (pressure-temperature rating)
Structural length: Meet ASME B16.10 standard (compact design)
Pressure level: Covers CLASS 150~2500LB (up to 42MPa)
Welding end specification: Socket weld complies with ASME B16.11, suitable for Sch80~Sch160 pipelines
Valve body material: Carbon steel (A105, WCB) Stainless steel (304/316L) Chromium-molybdenum steel (WC6/WC9)
Sealing surface: Carbide cladding (such as Stellite, hardness ≥HRC55)
Inspection standard: API 598 (leakage rate ≤0.01ml/min)
