Pilot Operated, Spool Type, Slip-In Valve - PDMC10S30P
POA
The proportional pressure reducing valve PDMC10S30P is a pilot-operated, 3-way spool-type valve.
When it has no energy, it vents the port 1 (consumer) via tank port 3. The pump port 2 provides a constant small flow of pilot oil to tank port 3. When the inlet pressure and the volume required fluctuates, it provides an almost constant outlet pressure - depending on the energization of the coil.
Plus, when the control current increases, the solenoid coil exerts a force via the pilot line on the pilot spool. Thereby, this will connect port 2 (consumer) with pump port 3. This will also compress the reset spring of the control spool.
So, if as a result of external factors, the pressure at port 1 rises above the preset pressure, the valve opens from port 1 (consumer) to tank port 3. This reduces the flow from pump port 2 to port 1 (consumer). This reduction will happen until the pressure across port 1 is equal to the pre-set pressure value.
What's more, any pressure at tank port 3 is additive to the pre-set control pressure.
Features:
- A compact design
- An excellent dynamic performance
- A low pressure drop due to CFD optimized flow path
- A control pressure reduction is possible right down to 0 bar.
- Excellent curve characteristics, also when there is inadequate primary pressure (the max. control pressure is 1.3 bar below the primary pressure)
- External surfaces corrosion-proof
- Hardened and ground valve components to ensure minimal wear and extended service life
- Some application example: clutch control
- A screen filter protects the pilot from contamination
