Control Valve CV-8450 & CV-8750

 

Description

High-performance globe control valve range is completed by CV-8450 and CV-8750 series, characterized by low-noise or anti-cavitation cage trims.
Trim design, single cage or multi-cage, material selection and precise machining make them suitable for  severe service conditions due to high pressure drops, noise or cavitation.
Cage guide minimizes vibrations and wear; these features and optimized stroke lengths result in a superior performance control. 
These valves can be supplied with pneumatic, electric or piston actuators for high pressure applications.
Straight or angle bodies are available; standard flanged connections or connections in accordance with process licensor requirements may be supplied upon customer request.
Forged body is available on small size control valves or when required by process licensor.
