550 Connection code 80 / Valve body material code C2. Angle Seat Globe Valve, Metal

Transcription

1 Angle Seat lobe Valve, Metal Construction The EMÜ pneumatically operated / way angle seat globe valve has a low maintenance piston actuator. The valve spindle is sealed by a self-adjusting gland packing providing low maintenance and reliable valve spindle sealing even after a long service life. The wiper ring fitted in front of the gland packing protects it against contamination and damage. Features Suitable for inert and corrosive* liquid and gaseous media Substantially reduced installation dimensions when using the body with male threads which can be installed using union nuts Materials of all medium wetted parts can be selected to suit relevant applications Higher media temperatures Versions according to ATEX on request Advantages Stainless steel actuator for simple cleanability, corrosive atmospheres Various types of valve body connections ood flow capability Low weight Standard gland packing suitable for vacuum Optical position indicator is standard for NC control function (optional for NO and DA control functions). Accessories: - Electrical position indicators - Combi switchboxes - Electro-pneumatic positioners/process controllers (see data sheet EMÜ control valve) - Stroke limiter Suitable for contact with food according to Regulation (EC) No. 9/ *See information on working medium on page Sectional drawing Connection code 8 / Valve body material code C

Bleed hole in the actuator To bleed the control medium, the pneumatic actuator has a bleed hole that is located on the side of the actuator housing (control function normally closed). In certain areas of application (e.g. the foodstuff industry), dirty water or cleaning media could enter through this bleed hole and penetrate the actuator, thereby adversely affecting correct operation. A special bleed system with lip check valve is available for these applications, which prevents such functional impairment. The bleed hole at the side is then closed.
