Function and Design

Quality valve, casted in stainless steel with firesafe design.

Three-piece ball valve.
No disassembling or changing of gaskets is necessary when the valve is welded in.
The design with blow-out safe stem prevents the stem to blow out at pressure hammer.
Mounting flange according to ISO 5211 for actuators.
No dismantling of valve at service and installation of mounting flange.
Valves from DN50 have round body and end piece.

Accessories and Options

Can be provided with different types of actuators and limit switches. (See separate datasheet AT 3830, AT 3831, AT3840, AT3841, AT 3900)
The valve is available with different types of accessories and in different performance as:
Stem extension, Cavity fillers, spring return lever with spring-to-open or spring-to-close function. Fire-safe design, three-way valves, heating jacket, Cryo performance, double gasket box, tank bottom valve, high pressure performance.
Three-piece valves give many variations for connection, for example one weld end and one threaded end. NPT threads and customer related welded ends.
