Accessing reserves is becoming more challenging than ever before.

2 In order to enhance recovery rates cost-effectively, operators rely on their hardware. Reliable Valves are a vital component of hardware requirements. With two decades experience, we have the edge when it comes to designing and developing small bore Subsea Valves . We pioneered metal-to-metal sealing technology that reduces the risk of contamination and failure. We employ some of the brightest minds in the industry to stretch the boundaries of design with creative engineering. The outcome is bespoke products that help engineers solve their design challenges. We like to think of it as a partnership approach. 02 Subsea Rotary gate Valves20-year field provenOur Rotary gate valve is beautiful in its simplicity. With 100% continuous metal-to-metal design across stem, seat-to- gate and seat-to-body, it performs reliably even with the dirtiest of fluids. The valve s innovative wiping action means it is self-cleaning, which further promotes all adds up to better quality and cost-efficiency.

3 And that means maximum assurance surrounding safety, performance and design reduces the size and weight of the product. It has minimal moving parts and a time-saving quarter-turn mechanism that can be operated manually or with hydraulics. Even in the event of over-torque the internal parts of the valve cannot be damaged; it will continue to rotate and function as Christmas tree and manifold has its own specifications. That s why our Valves are custom-made in line with their purpose and the space envelope. Robust and simple, each of our Rotary gate Valves can suit many applications and various media, from hydraulic fluids to well fluids to injection chemicals. Porting and mounting arrangements can be tailored according to need. Body size, stems, seals and ROV interfaces can be rationalised if receptacleManual Rotary visible position7 valve manifold blockSubsea Rotary gate Valves 03 FeaturesOur Rotary gate Valves can be supplied in a wide range of operating pressures, working pressures and operating temperatures.
