Valtek.

Founded in 1965, Valtek revolutionized traditional control valves by adding a high-pressure piston actuator to enable maximum stiffness, plus a simple, one-touch calibration positioner. Superior control, easy operations, reliability, long life, parts interchangeability, ease of maintenance, and prompt delivery are hallmarks of the Valtek brand. 

Valtek control valves are designed as a complete system which includes the valve, actuator and positioner. The products are widely used in power, chemical, oil & gas, water, and general industry applications.
