Technical details
Function and application
The PDE3K*, PRE3K*, PRE10K*, PRE25K* and PRE32K* are explosion proof proportional pressure control valves, direct and pilot operated, for subplate mounting. They are compliant with ATEX, IECEx, or PESO requirements and are suitable for use in potentially explosive atmospheres, for surface plants or mines. A low temperature version (up to - 40 °C) is also available. They are used to modulate the pressure of the hydraulic circuit and allow the use of the entire flow of the pump, even with pressure values near the set value. They have a mechanical pressure limitation feature inside the pilot stage, for higher safety of the application. The valves are available with 12 or 24 V solenoid. Several connection types are available, metric or NPT type. Cable glands are available. Share | Contact us
