Bonney Forge HL-11-LE Valve

Bonney Forge HL-11-LE 3/4 in. NPT gate valve delivers reliable, tight shutoff in demanding piping systems with an 800 lb class rating and low-emission packing. This OS&Y valve from the HL-11 family features inlet socket weld and outlet threaded (NPT) connections, enabling a versatile end configuration for threaded piping on one end and welded connections on the other. The body is carbon steel (A105/A105N family), with trim including a corrosion‑resistant ASTM A479 410 HF seat, ASTM A479 410 stem, and ASTM A182 F6a wedge, plus a self‑aligning two‑piece packing gland and spiral‑wound gasket for a durable seal and integral backseat. It is rated for up to 100°F (38°C) and up to 1,975 psi at that temperature, with a flow coefficient (Cv) of about 19, making it suitable for mid‑range flow control in oil, gas, chemical processing, or general industrial piping. The valve weighs roughly 5 lb in this size and is designed for manual operation within the Bonney Forge HL‑11‑LE specification, offering robust performance and compatibility with ASME B16.34/API 602 style design. Typical applications include isolation in process lines, power generation, water treatment, and other industrial systems requiring reliable gate isolation with NPT threaded ends.
