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.
