Danfoss Pneumatically Operated Valves
Angle seat valve types, also known as air operated angleseat valves or externally operated valves are the optimum valve choice when a standard solenoid valve is not able to do the job.
The angle seat valve is a real trouble shooter solution for difficult conditions; it allows very large flow rates, it can operate from zero differential pressure and with high media temperatures, it operates at high viscosities and with dirty media, and it operates in EEx areas, merely by placing the pilot valve outside the area.
Danfoss externally operated angled seat and axial valves AV210, HP220, HP230N and EV220X (EVSI)spec. are designed for more specialised applications, such as: Media with high dirt content or fire sprinkler systems.
The valves are operated by a pilot medium under pressure, usually compressed air but also oil, water or steam. The valve is equipped with a pneumatic actuator supplied by a three-way solenoid valve. The pressure of the pilot medium enters the actuator cylinder and acts on the piston, which allows the seal to open or to close through the stem. The return of the seal into its rest position is usually achieved by a return spring that can be found in the pneumatic actuator. In the double acting configuration there is no return spring and the pilot medium is used both for opening and for closing the valve. Applications of Danfoss angle seat valves - The trouble shooter valve has a countless number of application possibilities:
• Cooling
• Pre-heating
• Sterilizers and autoclaves
• High pressure lubrication
• Steam distribution
• Bottling
• Equipment for textile production
• Equipment for industrial steam pressing
• Mixing of paints, inks and colours
• Equipments for industrial washing and cleaning and many more… |
