NuStar API 6A / 17D gate valves are used to control the flow of fluids in Christmas trees, manifolds, pipelines and surface wellheads.
Gate valves can be provided in a variety of configurations based on project requirements or customer preference for pressure ratings 2,000-10,000psi. NuStar offers both slab style (one piece solid gate) and expanding (split type) gate designs. The slab-style gate valve is a straightforward and simple design and comes with bi-directional metal-to-metal sealing arrangement. Slab gates may also be used when wireline cutting is a requirement.
