Intended use
The type examined safety valve HSV is a component of the unintended car movement protection in down direction according to EN81-2:1998 + A3:2009, EN 81-20:2014 e EN 81-50:2014.
Combination of the safety valve HSV with a detecting component and actuating component, which are subject to approvals will constitute the complete protection, means that fulfils the requirements of a safety component.
If the current of HSV solenoid 12:A is correctly interrupted (see chapter 2.4.1.1 ) and all the operational limits are being observed (see chapter 2.5.1), the valve respects the requirements par.,5.6.7.5 e 5.6.7.6 EN 81-20:2014 independently of volume flow, load pressure and oil viscosity.
Hence proof of the function of the complete protection means can be provided by a travel at reduced speed (e.g. inspection speed).
The product must not handled in any way by unauthorised persons.
