Material Globe Valves
Globe valves by material groups linear-motion globe valves according to body and trim metallurgy, which usually governs selection once size, class and body pattern are set. The disc-on-seat throttling and isolation principle is unchanged, but the alloy fixes the pressure-temperature rating, corrosion and erosion resistance, high- or low-temperature suitability and compatibility with sour or oxidising media. Because globe valves often see throttling and high local velocities, trim metallurgy is as important as the body grade.
The common bands run from bronze and brass for low-pressure water and utility service, through A216 WCB carbon steel for general hydrocarbon and steam duty to BS 1873 and API 623 in ASME 150-2500, to A351 CF8 and CF8M stainless (SS304/SS316) for corrosive and hygienic lines. High-temperature power and refinery service uses A217 chrome-moly grades such as WC6 and WC9, while low-temperature duty uses A352 LCC/LCB. Aggressive and sour media call for duplex, super-duplex or nickel alloys such as Inconel, Monel and Hastelloy, with NACE MR0175/ISO 15156 compliance where H2S is present and the pressure envelope per ASME B16.34. Shell and seat testing follows API 598 or BS EN 12266-1.
Trim is matched to the body and the throttling duty: 13Cr, Stellite-faced or hardened stainless seats and discs resist wire-drawing and erosion at partial opening. Bolted-bonnet OS&Y rising-stem construction is standard, with pressure-seal bonnets for higher classes. End connections span flanged ANSI B16.5 RF/RTJ, butt-weld, socket-weld and threaded across carbon, stainless and alloy.
Handwheel, gear and factory-mounted electric or pneumatic actuation is available across all metallurgies, with documentation matched to the grade, where specified.
Himalay's MSME partners manufacture globe valves across these metallurgies with testing per API 598, BS EN 12266-1 and ISO 5208, material traceability, and PED-CE (EU), SABER (Saudi Arabia) and NACE MR0175 (sour service) coordinated as part of the standard order flow.
