Type 32 Hydraulic Drilling Choke
The aXoN Type 32 drilling choke utilizes two flat tungsten carbide discs with a half round cut out in each disc, available in manual and hydraulic configurations. one disc remains stationary while the other rotates, providing a variable orifice according to requirements. In addition, the lapped matting surfaces of the discs provide a positive seal when the choke is closed. Moreover, the choke control panels are available in single or dual choke operation.

FEATURES / BENEFITS
operating features
- Hydraulic fluid applied to a rotary actuator rotates the disc to precise choke control of the process fluid
- Stem (or fork) attached to the rotating disc is sealed in the choke bonnet and connected to the actuator assembly
- Visual choke position is made in an open area between the choke bonnet and actuator
- Variable, low-pressure pneumatic, signal relays the choke position to a remote choke control panel
- replaceable wear sleeves located below the carbide discs protect the choke body from flow wear and turbulence
- Pressure relief valve, located on the choke body, ensures any trapped pressure is released from the choke prior to bonnet removal
Control Panel
- operated with hydraulic fluid from an air-operated pump in the remote choke control panel
- Choke control panels available in single or dual choke operation
- battery operated pump stroke counters, choke position indicator, remote manifold pressure transmitter gauges, and manual pump back up also provided in the choke control panels
