Valtek
Official website: www.flowserve.com ↗Valtek was founded in 1968 in Springville, Utah, with a focus that has not moved since: control valves for hydrocarbon, power and severe process duty. Now part of Flowserve, the brand pairs a distinctive cylinder-actuator style with globe and rotary bodies, and its Mark One is one of the most recognized severe-service globes in the Americas.
The catalogue centres on the Mark One and Mark Two globes with cage-guided trims, the Maxflo rotary platform for high capacity and tight shut-off, and Valdisk butterfly valves for large bore. Severe-service depth is the selling point: MegaStream and related anti-cavitation trims, flash-tight configurations, cryogenic extensions and live-loading as standard practice. Logix digital positioners complete the loop, and the whole stack is engineered for the rugged end of oil and gas duty.
