Parker Hannifin, the worldwide chief in movement and management applied sciences, is unveiling a sequence of valves examined to ISO 15848-1 Class C, a normal that units out the measurement, take a look at and qualification procedures for fugitive emissions from industrial valves
The Class C valves complement Parker’s present options for the extra stringent Class A and B leak fee designations, while minimising funding required by the client.
For corporations working within the chemical, petrochemical or pure fuel industries, the explanations for minimising emissions to the environment from industrial valves embrace environmental targets, authorities rules and plant/employee security. An unbiased take a look at home witnessed and licensed the total manufacturing unit exams accordingly.
To attain ISO 15848-1 Class C certification, a valve should display lower than a sure leak fee over a predefined variety of operations (cycles). Moreover, the valve should stay inside this restrict whereas enduring predefined temperature fluctuations. Each Parker Hello-Professional ball valves and H sequence needle valves met the factors and now carry certification to ISO 15848-1 Class C. The Hello-Professional ball valve efficiently accomplished a take a look at of 205 cycles at a take a look at temperature of -50°C, reaching a stem sealing system leak fee of 1.2 x 10-6 and a take a look at of 205 cycles at a take a look at temperature of +160°C, reaching a stem sealing system leak fee of 1.0 x10-6. The H sequence needle valve efficiently accomplished a take a look at of 205 cycles at room temperature, reaching a stem sealing system leak fee of two.0 x10-6. Each valves had been examined utilizing Helium because the take a look at media.
Parker’s Hello-Professional high-performance Class C ball valves provide full chilly working strain scores as much as 414 bar, giving 100% bubble-tight shut-off and steady repeatable efficiency. That includes a real two-piece, quality-assured design, physique leakage paths are decreased to a minimal. The identical high quality, reliability and worth is accessible from Parker’s H sequence Class C needle sample hand valves, which permit exact circulate regulation for all kinds of media in low-flow functions. As customary, the needle valves have metal-to-metal seats to make sure 100% bubble-tight shut-off.
Each valve sequence characteristic totally built-in tube connections utilising both Parker’s superior benefit of proprietary A-LOK (two-ferrule) or CPI (single-ferrule) becoming applied sciences. This essential technical characteristic not solely facilitates fast set up, but in addition eliminates the necessity for taper threads and thread sealant and, in flip, the potential for an exterior leak path. This will additional scale back general plant emissions.
One other technical characteristic of the valves that helps ISO 15848-1 Class C accreditation is a strong design of packing across the stem. The stem inside industrial valves is a transferring half, so a sturdy surrounding sealing idea is crucial to forestall leaks throughout movement, and in enduring the variety of cycles and temperature fluctuations set out within the ISO 15848-1 Class C customary.
With this growth, course of vegetation, system integrators and pure fuel distributors can make the most of Parker ISO 15848-1 Class C licensed ball and needle valves that assist to minimise emissions and enhance security.
