Unique DV-ST UltraPure

Unique DV-ST UltraPureConcept

The standard Unique DV-ST UltraPure is designed either for manual operation or for Pneumatic operation. The valve consist of a valve body, diaphragm, handle or actuator. Optional Sensing and control units are available. With a fully modular design the Unique DV-ST UltraPure can be built to meet virtually any demand within most industries.

The valves are primarily used in biotech and pharmaceutical industries however they are also widely used in aseptic and hygienic processes as well as in utility systems within dairy, beverage and food industries.

Working principle

Manual operation – A simple turn of the handle will push the compressor downwards on the diaphragm, pressing the diaphragm against the weir of the valve body thereby closing the valve.

Automatic operation

The actuator controls the axial movement of a piston, thereby opening or closing the valve depending on the actuator function.

Valve Body Design

The valve bodies are available in a wide variety of valve types and configuration options (dimension standards, connections, surface finish and material).

• 2-way
• T
• Tank outlet
• Tandem
• Multi-port

How it works

Construction

The standard Unique DV-ST UltraPure consists of a valve body, diaphragm, handle or actuator. Optional automation and control units are available. With a full modular design, the Unique DV-ST UltraPure can be built to meet virtually any demand within the biotech and pharmaceutical industries.

Operating principle

The standard Unique DV-ST valve range is designed either for manual operation or for automatic operation.

Manual operation

For manual operation, the Unique DV-ST UltraPure is controlled by means of a handle. A simple turn of the handle will push the compressor downwards on the diaphragm, pressing the diaphragm against the weir of the valve body thereby closing the valve.

The handle can be made of full stainless steel, stainless steel composite, full composite or an epoxy version. All have a standard optical positioner and over closure protection*. As an option, the handle can incorporate a lockable function for security. The handle is fitted onto the valve by means of four screws and bolts.

*Except composite handle.

Automatic operation

The Unique DV-ST UltraPure can be controlled from remote location by means of compressed air using a pneumatic actuator. The actuator controls the axial movement of a piston, thereby opening or closing the valve depending on the actuator function.

The actuator is available in three standard versions: normally closed (NC), normally open (NO) and air/air activated (A/A). All versions have an integrated optical positioner. The actuator is fitted on to the valve by means of four screws and bolts.
