Description
DD: Flow Diverter
DDL and DDM are flow diverters with 6 ports, 2 positions. These valves allow one pressure source (one set of working ports) to power two independent circuits. The solenoid switches the flow from one application to another. There is an external drain port option that allows operating pressures up to 4,650 PSI (320 Bar). Up to five DD* modules can be bundled to operate with one set of supply ports. These valves are supplied with a zinc-nickel plating which helps them to withstand the harshest environmental working conditions.
- Zinc-Nickel plating standard
- External drain options for higher pressures
- Various voltage and connector options available
HDR: Self-Reversing Valve
The HDR valves are directional control valves hydraulic actuated, with self-reversing spool with porting pattern compliant to ISO 4401-03 and ISO 4401-05. These valves reverse the flow direction when the flowrate stops in A or B line (i.e., when a cylinder reaches the end stroke). The reversing process is independent of the working lines pressure. These valves are supplied with a zinc-nickel plating making them the perfect choice for mobile and environmental applications that require better protection. Salt spray resistance up to 600 h (test according to UNI EN ISO 9227 and UNI EN ISO 10289 tests and standards).
- ISO 4401-3 (D03) or ISO 4401-05 (D05) valve mounting pattern.
- Zinc-nickel plating standard
Cartridges: KCB (Coming soon)
Pilot Operated Check Valves & Counterbalance Valves
Screw in, cartridge type, guided poppet, hydraulic pilot operated check valve. Use as a blocking or load holding device for high pressure applications. Counterbalance valves are typically used with cylinders to safely hold suspended loads and deal with over-running loads. This valve can also be used with hydraulic motors and is then commonly called a brake valve. Both counterbalance valves and pilot-operated check valves can be used to lock fluid in a cylinder to prevent drifting.
