Single Seat Valves & Double Seat Valves

Alfa Laval’s range of single seat valves consists of large numbers of purpose-designed valve units that are very robust and flexible. They are ideal for use in processes with a high hygiene standard.

On the other hand, double seat valve concept provides modular solutions that are easily tailored to any specific requirement. The double seat design provides long-lasting, spillage-free operation thus minimizing the risk of product contamination. The use of double lip seals provides added protection to ensure safe and hygienic operation.

Dependable design

Alfa Laval Tri-Clover 700 Series valves feature a durable and dependable design with rugged plastic stem bushings, which eliminate metal-to-metal galling. In addition, the stem is threaded to the actuator shaft, eliminating the coupling between the stem and actuator, thereby ensuring proper alignment. Bushings at each end of the cylinder support stem also ensure perfect alignment. Finally, each valve features a heavy-duty bonnet and body ferrule design that will stand up to years of pounding from hydraulic shock.

A variety of styles and sizes

Alfa Laval Tri-Clover 700 Series Valve are available in both long and short actuators, including a wide selection of shut-off and divert valves. Sizes range from 2 in (50 mm) to 4 in (102 mm), in normally opened or closed positions. A 32Ra surface finish is standard, with several valve body combination options to choose from.

Helping fill your valve project gaps

Even in this era of continuous mixproof processing, Alfa Laval Tri-Clover Valves 700 Series are the perfect valve project gap filler. Specifically, if a simple divert valve is needed, consider a 761 divert valve. Or, if a section of your process requires flow diversion, install a series of 762 Flow Diversion valves – as shown.

The Alfa Laval Tri-Clover 700 Series Valve is remote-controlled by means of compressed air. It has few and simple moveable parts which results in a very reliable valve.

As an air-operated seat valve, it can be configured with either a short-stroke or long-stroke actuator. The 761 valve has a flexible sanitary design, allowing it to be used in a wide range of applications as a stop valve with two or three ports or as divert valve with three to five ports.
