Rexroth Air Valves

Topco Oilsite Products Ltd. Is the master Canadian distributor of Rexroth pneumatic controls used in oilfield applications.

These highly engineered and quality driven products lead the industry with state-of-the-art technology to provide reliability, a wide range of capability, and ease of use.

Rexroth manufactures 4 way directional control valves in various solenoid and air pilot versions. These rugged valves are found in the most demanding applications and the use of internal ceramic plates repels contaminants while sealing and providing stick-free operation.

Rexroth oilfield valves may be used on mobile equipment and are well known for both reliability and precise control.  The Type “A” Pilotair directional control poppet style valve is ideally suited for use in frequent opening and closing due to ease of operation, fast response time, and the ability to tolerate contaminated air.  They are manufactured in 3-way, 4-way, and with multiple 3-way functions.  The Type “P’ Rotair directional control valve features a single handle operation with up to 8 handle positions and is ideal for transfer valves and the control of multiposition cylinders.

Rexroth oilfield actuators/positioners are compact pneumatic devices used in such applications as the accurate positioning of diesel engine governor control arms, butterfly valves, carburetors, and low force mechanisms.  The popular A-2-H actuator comes in four pressure ranges up to 90 psi.

Topco maintains a large inventory of Rexroth pneumatic controls in our Edmonton distribution centre and is able to supply most product requirements on short notice.
