Drallim Smart Valve Monitoring fully analysed
Drallim Smart Valve Monitoring (SVM) has completed its FMEDA analysis by EXIDA; the resulting analysis shows SVM to have a Safe Failure Fraction (SFF) of 100%.
PIVs were first made in our factory at Whyteleafe just south of London, then, to allow for expansion, the company moved to its Bexhill site in 1968.
Once again outgrowing these premises, Drallim moved further south to its current purpose built headquarters in St Leonards-on-Sea near Hastings in December 2003.
The PIV range starts with the Series 40 valve.
A 4-port version, which is designed with total flexibility in mind.
Flexibility comes from the fact that each valve can have its own unique inner camshaft arrangement and, when mounted in a stack, allows different fluids to be passed through each bank.
The Series 60 range of valves offers 6 ports.
It encompasses the same proven design as the Series 40 but offers far greater permutations.
The Series 70 and 95 valves are 4 port valves that offer a higher flow capacity than the Series 40.
Positive positioning is standard on all valves and comes from an indexing mechanism allowing the operator to have general feel of the various positions of the valves.
Should it be required, security can be provided by keylocking of the valve.
An electrical interface is also available by a rotary electrical switch directly coupled to the base of the valve.
These can be supplied as a standard switch or ATEX certified for use in hazardous areas.
