Description

AST manufactures a complete range of high-performance globe control valves, whose sturdy construction makes them suitable for moderate and severe service conditions.
CV-8000 series is characterized by a sturdy plug and a guide designed to minimize vibrations and wear. Precise machined plug contours 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, angle or three-way bodies are available; standard flanged connections or 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.
AST has been awarded fugitive emission certification according to ISO15848-1; CV-8400 may be marked as follows:
ISO FE AH – CC3 – SSA0 – t400°C – CL600– ISO 15848-1.
Low noise or cavitation control trims are also available (see CV-8450 CV8750).
