Enerpac PID Inline Dump Valve, Intensifier
The internal bypass valving enables high output flow rates and includes a dump valve and eliminates the need for an external pilot check valve. The compact and self-contained design allows for ease of installation. Select fit of all internal components that provides long operating life. It includes FL2101 filters and a VFC1 flow control valve. 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.
The outlet filter in port is the high-pressure outlet while the inlet filter and flow orifice in port is the low-pressure inlet. The built-in dump valve is the valve type.
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 the 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.
