FIP has developed a VKDIF DUAL BLOCK® ball valve to introduce a high reference standard in thermosplastic valve design. VKD is a True Union ball valve that meets the most stringent needs required by industrial applications.

In addition to manually operated version, the VKDIF is also available in configuration with electrical actuator VKDIF/CE. The actuators are firmly connected to the valve with a special module Power Quick made by FIP entirely produced in technopolymer PP-GR.

The VKDIF/CE is produced using actuators complying with current regulations and selected by FIP according to its requirements of quality and reliability.

The efficiency of these valves, tested according to the company quality standards, is guaranteed by the expertise and know-how that FIP dedicates to the manufacture of its products.
