The Manufacturer

Built in Britain.
Proven in the field.

Blackhawk Valves is a UK-based manufacturer of critical-service valves for the oil and gas industry. From API 6A wellhead equipment to API 6D pipeline systems, every valve is engineered, machined, assembled and pressure-tested before it leaves our factory.

Our engineers work directly with procurement teams and EPC contractors to tailor materials, trim and actuation to the duty — sour gas, cryogenics, extreme pressure, fire-safe.
