DTP series Adjustable angle choke control valves

Features & Benefits

Generally located at the wellhead, valves are designed for Oil&Gas processing, water and gas injection and gas lift. Velan’s DTP series are the optimal solution for controlling high levels of fluid pressure in the most difficult conditions such as dirty and corrosive fluid services.

Angle choke are traditional robust angle valves with a multistage trim and a corresponding plug specifically designed to provide high energy dissipation.

The valve’s multi-stage technology and discrete tortuous path design divides the flow into many streams reducing pressure and fluid velocity avoiding cavitation, flashing or erosion phenomena.

Velan ABV offers the advantage of intechangeable plug and trim components, the valve has no welded internal parts, resulting low maintenance costs.

Actuation can be either hydraulic or pneumatic depending on the speed requested. Stepper actuators are an option for reaching the highest level of accuracy.

Material selection is fully customizable to meet customers project specifications.
