Drain Valve

The excavator pipe rupture valve is used wherever so required by the standards ISO 8643, EN 474 and DIN 24093 for excavators with a lifting device (e.g. a load hook on the bucket). The actuators concerned are the lift cylinder, the stick cylinder and the adjusting cylinder. The valve should also be used on machines in which a pipe rupture on the actuators could produce dangerous situations (e.g. machines for materials handling and demolition).

The excavator pipe rupture valve, series CFS (Compact Flow Control and Safety Valve), prevents uncontrolled lowering of the actuator in the event of a pipe or hose rupture. In addition, the CFS valve holds the actuator in its position when the main valve is centred. The valve also includes a secondary pressure-relief function, which protects the actuator against overload. The inlet and actuator ports on the CFS are standard SAE flanged ports, and the valve can therefore be retrofitted to existing equipment without any difficulty.

Excavator pipe rupture valves prevent uncontrolled cylinder movement in the event that a pipe or hose bursts. The ESV valve fulfills all of the requirements of the ISO 8643  and EN 474-5 standards for excavators.

Load-control valves in this series prevent hydraulic actuators from running ahead of the available oil supply. In one valve, they combine the functions of load-holding, safety and pipe rupture protection.

Whenever loads are to be precisely moved, placed and held, leak-free load-control valves from the CINDY series are the right solution. Load-control valves in this series prevent hydraulic actuators from running ahead of the available oil supply. In one valve, they combine the functions of load-holding, safety and pipe rupture protection. Leak-free load-control valves in this series are ideally suited for use in high-pressure applications up to 420 bar (6000 psi). With a variety of optional components, the series can be extended and adapted to the requirements of the system.
