Elevator safety valve L 20

shut-offplug

The L20 has been designed to fit in all types of Blain ¾" series of valves without the need to change any existing piping and thus is ideal for renovation projects. The L20 can be either ordered pre-assembled with a new Blain control valve or alternatively ordered as an upgrade to make an existing Blain valve compliant to european safety standards (EN 81-20/50 unintended car movement - UCM). A separate tank connection is required from L20 in case of renovation, however for a new factory assembled valve, there is no need for a separate tank connection. As no extra fittings & adapters are required, the size of the complete unit remains compact. This also results in further savings and considerable less installation time. It’s an easy to implement, plug and play system.
