Hoist Safety Valve - 3/4" BSP
Air Operated
In Australia, all tippers are required by law to include protection against hose failure and to prevent any tipper body falling uncontrollably if a hose does burst - in fact, you may be required to have a Hose Safety Valve to enter some sites.
The valve is an inline, direct acting, pneumatically operated hoist check valve for use in blocking or load holding. The valve is direct mounted to the Lift cylinder by its hydraulic connecting fitting and secured utilising clamping holes provided. It’s ease of fitment gives it the highest degree of suitability for both new installations and retro fits to existing Tippers.
Raise: Flow comes from the truck mounted directional valve, enters port 1 of the APV valve and exits its port number 2 straight into the Lift Cylinder.
Lower: Air pilot pressure simultaneously operates the Truck directional valve to lower function as well as opening the check valve in the APV valve from port 2 to 1 which then allows oil to leave the cylinder and return to tank via the directional valve.
COMPLIANCE: This valve can be utilised as the controlled lowering device on AS1418.8 compliant Tipper Hydraulic Circuits.
