Check Valves, Size 04 … 40 RKVE…
Description
Compared with the previous series, the new generation of hydraulic check valves offers up to 50 percent higher flow rate for the same pressure differential. The larger flow rate saves energy and in many cases allows a smaller valve to be used, which in turn has a positive effect on costs and installation space.
The use of high-quality materials, high-precision production and 100 % quality inspection ensure better use, more performance and higher availability of the machine.
For size 04 up to 16 a metal cutting lip on the valve provides a metal-to -metal seal.
For size 25 up to 40 an external O-ring seals the leakage path between the valve and cavity wall.
The variants differ by:
VD = standard flow-optimized variant
VD22 = optimized for reduced pressures up to p = 220 bar
KB = compact design
Check Valves, Size 04 … 40 RVVE
Description
Ball-type, screw-in design, series RVVE
Check valves prevent any flow in one direction. In the opposite direction, free flow with minimal pressure drop is possible.
Dual Check Valves PDCV
Description
Series PDCV-08 pilot-operated check valves lock a cylinder in any rest position. They are intended for direct mounting in the cylinder as weel as for mounting in a manifold block or a line mounting body.
Excavator Pipe Rupture Valve CFS
Description
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 Valve ESV
Description
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 BBV
Description
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.
