IDV – Impulse Dosing Valve

The patented impulse dosing valve is the result of many years' experience in the development and production of components in the field of volumetric dosing of lubricant. The IDV – impulse dosing valve is in its element wherever a precise volume of lubricant has to be dispensed accurately.

It is controlled by means of a mono-stable, quick-acting pneumatic valve actuated at a system pressure of 5 - 6 bar and can dispense up to 20 dot shapes per second. A corresponding number of activations means that different dosing volumes are possible with only one IDV without a significant loss of time.

Component parts of the impulse dosing valve

• Valve cartridge
• Valve connection block
• Nozzle adapter
• Replacement nozzle

Adaptation accessories

• Valve cartridges with different dosing piston diameters for dosing volumes of 0.3 mm³ – 40 mm³
• Standardised replacement nozzles with nozzle diameters of 0.4 mm – 1.5 mm or blast air supported dosing nozzles
• Regulated valve heating to improve flow properties and avert ambient temperature influences

Combination of accessories via modular design

Its modular design enables the best possible adaptation to specific lubricant properties and dosing requirements by combining various sizes of individual components in conjunction with optional accessories.

The benefits at a glance

• Contactless dispensing method
• Option for use in automated handling systems due to its small size and flexible positioning
• High process reliability
• Low primary medium pressure to prevent lubricant separation
• High dosing speed

The medium to be dosed is fed via the valve connection block to the IDV by means of a static pressure of 3 - 6 bar, where a non-return valve in the valve's dosing chamber prevents an uncontrolled release. Triggered by a quick action valve, the dosing piston in the valve cartridge is abruptly pressurised and plunged without clearance at high speed into the dosing chamber. The tensioned column of lubricant is driven towards the dosing nozzle and opens the non-return valve.

The great force of the impulsive compression stroke causes the lubricant to emerge from the nozzle with a high kinetic energy and correspondingly high flow velocity, while the abrupt stop of the dosing piston at the configurable end stop causes it to break off at a specified point thus achieving a precisely targeted lubricant application. The dosing volume can be set manually using the rotary valve cylinder, which restricts the stroke of the dosing piston.

The variety of lubricants and their fields of application, as well as product-specific dosing requirements, often dictate a dosing component that is individually tailored to the task.

In such cases, we offer our customers a comprehensive range of services based on the necessary expertise and technical possibilities, including a feasibility analysis and coordination of the dosing valve through to an automated system solution.
