The hose burst valve is open in the normal position and allows flow in both directions. If there is an excess of the pre-set actuating flow rate as a result of a hose burst, for example, the valve quickly closes and blocks the flow from port 1 to port 2. Add to Cart.

A Velocity Fuse, (Hose Burst Valve), is a safety device that senses the flow rate of hydraulic fluid out of a cylinder and ‘locks’ if the flow rate exceeds the allowable rate. A velocity fuse requires a flow potential large enough to meet the differential pressure setting. The flow normally required to trip the fuse is 30% above the rated flow. This usually accommodates flow surges without
Hydraulic hose burst valves are particularly suitable for elevating platforms, scissor lifts, bridge cranes and forklifts, due to their safe and responsive design. Pilot Operated Check Valves. Hydraulic pilot operated check valves are simply check valves which can be opened by an external pilot pressure. These designs of hydraulic valve are often abbreviated as P.O check valves, and are used

Viton withstands high temperature better than most other elastomers, and retains its good mechanical properties. Oil and chemical resistance are also essentially unaffected by elevated temperatures. Compounds of Viton remain substantially elastic indefinitely when exposed to laboratory air oven aging up to 204°C or to intermittent exposures up to 316°C. High temperature service limits are
24/6/2021· Hose burst detection is a software-enabled feature of the Eaton CMA advanced mobile valve. Using built-in pressure and position sensors, the CMA valve prevents major oil spill events by monitoring flow consumption on each service and closing the spools for that circuit if a large leak is detected. This dramatically reduces the amount of oil spilled, which can help:

Specialists in ISO 8643. Hose burst protection valves (HBPV) also known as lowering control device, load hold valves, hose rupture valves, craning valves, anti-drop valves, circuit installations and testing are required to meet the current Australian Standards 1418.8 (AS) ISO8643 2017. The general requirements of AS1418.8 relate to all forms of earthmoving equipment, including backhoes, front
hydraulic hose ruptures). One type of burst protection device is shown in photographs 1 and 2. Photograph 1: Burst protection fitted to boom cylinders. Photograph 2: Burst protection fitted to dipper arm cylinder. The Mobile Crane Code of Practice 2006 discusses the need for burst protection to be fitted to the boom and dipper arm of earthmoving equipment used as a crane (i.e. with a freely
Holury’s VPC Series hose burst valves allows free flow in both directions under normal working conditions, however, in the situation of a surge flow from ‘B’ to ‘A’ due to hose failure the valve immediately stops the flow. The burst flow can be set by increasing or decreasing dimension ‘S’ to be verified during final testing of machine.

Hose burst valves reduce the risk of components such as dipper arms collapsing under pressure. If the event that a hydraulic hose fails then these valves will stop the dipper arm from moving downwards. It is a key safety component for any earth-moving hydraulic machine.

Hose burst protection valves also known as load holding valves, hose rupture valves, hose rupture control valves, craning valves, hose safety valves, check and metering valves, anti-burst valves, counterbalance valves, controlled lowering device and over centre valves are required to conform to the ISO8643 regulation fitted on all earthmoving equipment used as a crane, where the rated capacity
Hose Burst Valves are designed to protect people and equipment in the event of a failure of an hydraulic hose. Australian Standards (AS1418.8) require earth moving equipment such as excavators, backhoes and front-end loaders, used to lift and transport freely suspended loads, be fitted with such a device to protection in the event of an hydraulic hose burst.
