manual op drilling chokes


The manual actuated drilling choke is actually a pressure control valve. Its

function in the system is to ensure pressure control during drilling operations and during a kick (blowout). The pressure is controlled by modifying the relative

position of the control elements, gate and seat, by moving the gate.

Gate and seat are from tungsten carbide and are reversible for double life


Standard orifice size is 51 mm (2").

Inlet-outlet connections are flanges according to API 6A.

Working fluids: water, crude oil, gases, drilling fluids, petroleum products.


Standard A and B dimensions are the same with hydraulic actuated drilling choke.

Other dimensions will be made on request.
