New sealing system for valve stems suitable for use with many chemicals

New sealing system for valve stems suitable for use with many chemicals

Bonomi (UK) has introduced an advanced sealing system for valve stems. V-Pack is a PTFE stem sealing system removing the need for an elastomer (HNBR/ EPDM/ MFQ, FFKM) O-ring, meaning that the valve is suitable for use with a wide range of chemicals. The result, says Bonomi, is a single valve, suitable for use in many different applications, without having to consider changing the elastomer O-ring stem seals.

The removal of the elastomer O-ring stem seal also has the benefit of increasing the temperature range (-40 °C to 180 °C) of the valve. And the performance of V-Pack has been fugitive emission tested in accordance with ISO 15848-1, covering the external leakage of stems and body joints of valves intended for use with volatile air pollutants and hazardous fluids.

This new option is available for Bonomi’s Valpres range of wafer, wafer-split, and split-body ball valves in carbon steel and stainless steel.

“V-Pack gives our customers even more options when it comes to selecting the optimal process valve for their application,” says Jason Hill, sales director at Bonomi (UK). “The V-Pack option now makes a single valve suitable for use with many chemicals, in many applications.”
