Virtually Indestructable Actuators for the World's
Most Demanding 1/4-turn Applications.

Whether you are in need of actuators for general industrial applications or specified applications such as Chemical, Power or Food Production, you can rely on QTRPAQ actuators. When other actuator's lives have been cut short, QTRCO's patented actuators, constructed of 316 stainless steel and other rugged materials, will still be providing you with longer lifetimes and fewer repairs. And if for any reason the QTRPAQ actuator does not live up to your expectations, we back our product with an impressive 3-year Performance Guarantee.

 

Rack & Geartm

Rack & Geartm actuators from QTRCO are available in 316 stainless steel, ductile iron and aluminum materials to solve the most difficult automation applications. Originally designed for food applications that typically see over 200,000 cycles per week, the Rack & Geartm actuators are designed for long life and can turn valves with a torque requirement up to 15,000 pound-inches.
The Flat Yoketm actuator design is an extension of a decade of Rack & Geartm development. Available in stainless steel and ductile iron with balanced design, and much lighter weight than comparable scotch yoke actuators, the new Flat Yoketm can turn most valves, with an available torque range from 20,000 up to 2.2 million pound-inches.
Custom built for specific applications, QTRCO engineers can create a full 316 Stainless Steel pneumatic, spring return linear cylinder for mounting to control valves. Use this when a spring and diaphragm would either rust away or just won't fit due to the typically large size of the diaphragm.
Eliminate the possibility of spurious plant trips with the QTRCO Partial Stroke Testing device. Using our proven Tandem Piston Technology, the QTRCO PST option is a pneumatic, remotely operated hard physical stop. What do you get? Zero possibility of valve overtravel during Partial Stroke Testing and peace of mind while testing your critical valves.
