SERVINOX RVO

The pig speed control unit (RVO) continuously and autonomously adjusts the most appropriate pig propellant pressure. It allows the speed of the pig to be continuously regulated during pigging. This system can be used whatever the characteristics of the line subject to the pigging process or the product to be recovered. The control unit is a stand-alone system, with instant access to data.

Pigging on transfer lines for all types of liquids Prevents pig jamming

This equipment is particularly suitable for lines conveying viscous, laden and/or solidifying liquids (creams, chocolate, caramel, paints, lubricants, etc.)

Design & Features

• Protects lines from water hammer
• Prevents pig jamming
• Eliminates the “karcher®” effect of the product at the end of the process
• Ensures the safety of users and facilities
• Adapts to products of different natures or viscosities that can be transferred on the same line
• Increases pig service life
• Detecting the end of a pig service life
• Detecting a leak in the line
