Severe Service Control Valve Proteck
SEVERE SERVICE CONTROL TYPE
Many valves are marketed for critical service control but few can provide the complete solution needed for the grueling conditions of severe service PROTEK® valve was designed solely for this purpose - to meet your specific control valve needs. Whatever your application, for severe service control, there is only one intelligent choice: PROVAL PROTEK® control valve.
PROTEK® is PROVAL of the line high performance specialty trim that offers a proven solution th those severe service applications where a true velocity control trim is the best of possibly the only answer. By limiting the fluid velocities inside the valve, PROTEK® stacked disc design precludes those problems typically associated with high vibration and poor control. Every PROTEK® trim is custom designed to meet the needs of the toughest liquid, steam and gas services in the power and process industries.
