Concept

Unique Single Seat DN125 and DN150 Valves are pneumatic seat valves in a sanitary and modular design giving a wide field of application, e.g. as a stop valve with two (2) or three (3) ports or as change-over valve with three (3) to five (5) ports
 

Working principle

The valve is remote-controlled by means of compressed air. It has few and simple moveable parts which results in a very reliable valve and low maintenance cost.
 

Standard Design

The Unique Single Seat DN125 and DN150 Valves come in a one or two body configuration. The actuator is connected to the valve body by means of clamp rings. To facilitate installation the valve is only partly assembled when delivered. The valve has welding ends as standard and is available with fittings as option. It is recommended, due to the valve size and weight, to use supporting equipment, handling and installing the valve. Guidelines are given in the instruction manual. Alfa Laval is not able to supply the recommended supporting equipment.
