Makers of everything from petrol pumps to dry-cleaning machines specify Danfoss valvesValves are usually a small but crucial part of a design, and not always easy to specify. But by working in partnership with Danfoss, you can get precisely the valve needed for your application as quickly and inex-pensively as possible. For example, thanks to the scope of our product line, we can often deliver what others might term “special” configurations directly from stock, saving you time and money. Where needed, we can modify our products to your specifications, giving you a valve optimized for the application. And where the specifications don’t yet exist, we’ll help you define them — build ing quality into your product from the start.

Benefits• Complete range of general purpose valves, including solenoid valves

and externally operated valves• Standard product line covers wide range of industrial applications• Includes stainless steel versions for aggressive media, and IP 67

General purpose solenoid valvesDirect, servo, assisted lift....We’ll help you select the right one

Danfoss offers an exceptionally wide range of solenoid valves, available in direct-operated, servo-operated and assisted lift versions. An easy, economical way to control and regulate fluids and gases, they are especially suitable for:

• Media with limited dirt content• Small to medium flow volume

A Danfoss sales engineer can assist you with sizing and application engineering, ensuring optimum performance and long operational life.

Externally operated valvesOur externally operated valves are designed for specialized and demanding applications.

These robust units are the right choice for:

• Media with high dirt content• Media with high viscosity• High ambient and media temperatures• Large flow volumes• Humid environments• Applications with low or unknown pressure conditions• Explosion harzard environments

Thermostatically operated valvesDanfoss self-acting valves are a simple and reliable way to control the temperature of water-cooled equipment. They do not require control air or electricity and are typically used in:

• Hydraulic systems• Injection moulding machines• Compressors• Vacuum pumps• Dry-cleaning machines• Distillation plants• Other machinery using water cooling
