Description
Spring-loaded safety valves available in full lift (VEYT) and proportional lift (VEYO) configurations. Designed for flanged end connections per DIN 2533/DIN 2544/DIN 2545, covering pressure ratings PN10 to PN40. Nominal diameters range from DN25 to DN100 with a maximum temperature of +80°C.
Selection notes
This safety valve is a spring loaded, full lift and proportional lift pattern, supplied for flanged installation.
Sizes run DN25 to DN100, in PN10, PN16, PN25, PN40.
The body is offered in GG 25, GGG-40 and GS-C 25, so the grade can be matched to the service rather than the other way round.
Seat and trim options are AISI 304. The seat, not the body, usually sets the temperature and medium limit, so confirm it against the service before ordering.
It is catalogued for Industrial Process.
Working temperature is max 80°C.
Built to DIN 3202-F32, DIN 2532, DIN 2533, DIN 2544 and DIN 2545.
