Single Seated Control Valve

Overview

CEPAI single seated control valve is a top entry globe type valve, which
is manufactured under ISO 9001 quality assurance system. The body
channel is streamlined by S shape with low pressure loss, high capacity,
wide regulating range, and high accuracy in flow characteristics. The plug
features with guiding area and good vibration resistance. The control valve
is equipped with mult-spring diaphragm actuator and compact in structure
as well as big in output force. This valve is designed to control a broad
variety of fluids, like steam, water, most of the medium and gases.



Design Features
· Reduced trim can be chosen to provide wide capabilities for site applications
· Balanced trims are suitable for high pressure drop and shutoff
· Hardened trims to handle high pressure drop applications
· Bellows seal for special medium
· Extended bonnet for low temperature
· Finned bonnet for high temperature
· Higher maximum valve flow coefficients
· Bigger body volume to reduce cavitations
