Valves
Our valve systems are engineered to provide reliable flow control, pressure management, and secure operation for demanding oil and gas applications. Available in a range of configurations, they include gate valves in DPF, DFL, DFL-R, DFLD (sand-proof double seat), DFC, and DFK series, as well as needle and cage chokes. The valves can be equipped with corresponding actuators and configured as integral combination valves or valve blocks for compact offshore applications. Designed in accordance with API 6A standards, our valves offer dependable performance across a wide range of temperature, material, and product-level requirements.
