Drilling Industry: Why order from us?

40 years of experience in oil field drilling rig air valves

With more than 40 years invested in the drilling rig, workover rig and pulling unit industries, DTI understands what parts and repair kits are necessary to keep pneumatic control systems running. We are not merely stepping in at an opportune moment for the oil industry. DTI carries all Rexroth (originally known as WABCO) directional and pressure control air valves for rotary drilling rigs, workover rigs and pulling units.

Keeping rigs running

DTI’s major focus is providing control valves for drilling and workover rigs. Kris Coleman, DTI owner, has been solving oil field air valve and actuator circuit problems for drilling operators, rig builders and well service personnel for 20 years. His personal consultations ensure you are getting the valve or actuator necessary for the application. From throttle actuators and brake control valves to valves for engaging and disengaging clutches, we know which valves will keep your rigs running.

Parts readily available

DTI maintains a complete stock of type “A” PILOTAIR pneumatic air valves, type “H” CONTROLAIR valves and A-2-H Actuators. We have seen customers of other vendors wait as long as 16 to 18 weeks for these products to be ordered. DTI has solved the problem of lengthy lead times by ordering our inventory more than a year ahead of time, so we can meet your needs when you need them met. Virtually all valves and the repair kits to service these valves are currently in stock in sizable quantities.

Rexroth or WABCO air valves are used for the following applications:

Bosch Rexroth directional and pressure control valves, actuators and cylinders provide the reliability, quality, ruggedness and precision needed to ensure safe, positive pneumatic control for clutches, brakes, transmissions and diesel engine governors for drawworks on oil drilling and oil well service rigs and associated equipment. The leader in the industry from the beginning, our products are found worldwide — wherever oil and gas are produced. Valves, such as our H-Controlair®, A-Pilotair®, P Rotair®, and D-Pilotair®, withstand the harsh conditions and are considered standards of the industry.

From the primary controls of the driller's console, to the pneumatic actuation of rotary tables, from sandline drums to winches and fracturing pumps — we have the pneumatic controls to fit the bill.

Some of the typical functions that utilize our controls are:

Engine Speed:
- Hand and foot control,
- Front and rear station control and station interlocks

Transmission:
- Powershift and automatics
- Cab and operator console stations: for primary drum and vehicle propulsion
