  1. PID321A

PID321A, 2.0 to 1 Intensifier, Inline, Dump Valve, SAE Ports, with port filtration and flow orifice


Model: PID321A   |  ECCN: EAR99    |   Harmonization: 8481809015
Series: PID   |  Product Line: Workholding Tools
  • Internal bypass valving enables high output flow rates
  • Includes dump valve, eliminates the need for an external pilot check valve
  • Compact and self-contained design allows for ease of installation
  • Select fit of all internal components provides long operating life
  • Includes internal filtration screens and internal flow restrictor orifices
  • When hydraulic pressure from an existing power source is limited, Enerpac oil-to-oil intensifiers serve to increase output pressure to satisfy the required application

Intensifier principle:

  • When oil is supplied to the inlet (IN) port it flows freely past the check valves (CV) and the dump valve to the cylinder and advances it.
  • As the inlet pressure increases the oscillating pump (OP) automatically increases the outlet pressure by the chosen intensification.
  • Once the maximum pressure is reached, the pump frequency lowers and balances at the maximum pressure.
  • Free flow from the cylinder to tank occurs when the directional control valve is switched to supply the R-port.
  • 10 micron filtration is required on all ports in the circuit to ensure trouble free operation. Filters and flow control included.
