Yancheng Cyber offers a wide range of surface, subsea, and drilling chokes to suit varying applications and operations.
Choke valves are used to control flow rate and reduce pressure for processing of produced fluids farther downstream. There are two basic body styles (adjustable and positive) and three body types.
Our choke valves have interchangeable bodies. The bonnet can be removed on the adjustable valve and replaced with the positive choke valve bonnet, and vice versa. In most cases users will determine the desired calibrated orifice size using the adjustable valve and then convert this to the positive valve with the corresponding choke bean in place.
