Industrial Gate Valves
Industrial gate valves are linear-motion isolation valves in which a flat or wedge-shaped gate is raised and lowered across the flow path by a rising or non-rising stem. They are designed for fully open or fully closed service, giving a near-straight-through bore with low pressure drop when open and a tight shut-off when closed. Gate valves are not intended for throttling, where partial opening can erode the seat and gate.
The family covers several design and size bands. Cast steel gate valves to API 600 serve general refinery and pipeline duty in sizes from 2" to 48" and pressure classes ASME 150 through 2500. Compact forged steel gate valves to API 602, and the related BS 5352 and ISO 15761, cover small-bore lines, typically up to NPS 2 and into NPS 4, in classes to 1500 and 2500. Corrosion-resistant cast gate valves to API 603 suit lower-pressure stainless and alloy service to ASME 600. Pipeline gate valves are also built to API 6D, and the European BS EN 1984 covers steel gate valves in PN and Class designations. Shell and seat testing follows API 598 or BS EN 12266-1.
Materials span A216 WCB carbon, A352 LCC/LCB low-temperature carbon, A351 CF8/CF8M stainless, and duplex or nickel alloys for corrosive duty, with bolted-bonnet, OS&Y, rising-stem and wedge or parallel-slide configurations. End connections include flanged ANSI B16.5 RF/RTJ, butt-weld, socket-weld and threaded.
Operation is by handwheel, gear, or factory-mounted electric and pneumatic actuators for remote and ESD service, where specified.
Himalay's MSME partners manufacture industrial gate valves 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.
