Slab Gate Valves Collection

Perfect for media with suspended particles, slab gate valves, also called through conduit gate valves, feature a solitary gate unit that lowers and rises between two seat rings. The self-positioned sealing surface of slab gate valves keeps the gate unit free from thermal deformation brought by the medium’s temperatures.

DomBor is the industry leader when it comes to long-lasting and affordable slab gate valves, utilizing the latest design tools and precision processing equipment to complete orders large and small. Through years of production expertise, our line of slab gate valves sees use in various oil and gas industries across the globe.
