The new VA40 Hose Burst Valve from Hydreco Hydraulics has a number of unique design elements that offer improved safety, better performance and improved environmental impact.

The hose burst valve is an inline safety valve that prevents the tipper body lowering in the event of a hose rupture.

The device uses an adjustable flow dependent check valve (also known as a velocity fuse), in a patented arrangement, that is ‘de-sensitised’ by the use of a solenoid valve with a separate tank line, they work in unison to provide reliable hose burst protection.

In normal operation the valve provides faster flow rates on lowering than all other designs. An added slow lower function (separate from the tipping valve) is available by activation of the solenoid valve only.

The use of a robust coupling sleeve to connect the device to the hoist and hose, allows for the best location of ports and hoses during installation.

This safety device complies with VSB6 and to the Australian Standard AS1418.8 Section 4.4.4 and is required to be installed in accordance with the Cranes, Hoists and Winches guidelines.
