The Kenmac KVV is an adjustable relief valve suitable for nonvented or vented inline applications in chemical, petrochemical and high purity gas industries. Available from Boiswood with pressure ranges up to 35bar, the KVV is ideally suited for use in analytical sample handling systems and on cylinder gas pressure regulators as a protective device to prevent excess pressurisation of sensitive components or overranging of the regulators outlet pressure gauge. The KVV can be used to protect pressure sensitive laboratory and inline process analysers; glassware from over pressurisation; and outlet gauges on single and dual stage cylinder gas regulators. The KVV is specifically designed for use with gases and liquids compatible with materials of construction and is manufactured using stainless steel and brass. It features convenient adjustment of the pressure setting through the outlet port, low hysterisis between cracking and reset pressure and operating temperatures up to 315C.
