Function and Design

Three-piece ball valve in antistatic design for simple service and maintenance.
No disassembling or changing of gaskets is necessary when the valve is welded in.
Homogenous floating ball for tight shut-off and low pressure drop.
Self-compensating stem packing gives a tight valve also with high operation frequency.
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 maintenance.
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..., AT 3900...)
The valve is available with different types of accessories and in different performance as:
Stem extension, Cavity filling, 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.

Installation

Valves with weld ends can be welded in without disassembling, provided that the ball is in the open position. See separate manual.

Maintenance and Spare parts

The valve construction permit a simple exchanging of all parts. See separate installation- and maintenance instructions AT 9980-3502.
