Slab Gate Valves

Slab Gate Valves (Through-Conduit Gate Valves) feature a single solid parallel-faced gate with a precision bore hole aligned with the pipeline bore when fully open. In the open position, the valve creates an unobstructed, continuous circular conduit that exhibits zero pressure drop, prevents turbulent eddies, and allows regular pipeline scraping (pigging) without risk of catching or jamming.

Zeron Fastners manufactures heavy-duty API 6D Through-Conduit Slab Gate Valves in forged and cast carbon steel, low-temperature steel (LCC/LCB), and stainless alloys up to Class 1500#. Equipped with spring-energized floating seats that maintain continuous bi-directional mechanical contact with the slab gate, delivering true Double Block and Bleed (DBB) isolation across cross-country crude oil, refined product, and high-pressure natural gas pipelines.
