Intensifer with Pilot-operated Check Valve

Intensifer with Pilot-operated Check Valve - ROEMHELD D8.757

• Intensification ratio 1.5 to 5
• Intensification ratio: 1:1.5 - 5.0
• Max. flow rate: 8 - 15 l/min (low-pressure side)
• Max. operating pressure 100 - 200 bar (low-pressure side)

Advantages:

• Compact design
• Pipe thread and manifold mounting connection possible
• Continuous flow rate
• Pressure regulation low-pressure side
• Expensive high-pressure pump not required
• High-pressure only where needed
• Cost-saving piping
• Pilot-controlled check valve integrated
• Sequence valve can be adapted

Application:

Hydraulic intensifiers convert a low input pressure into a higher output pressure according to the intensification ratio. In principle, smaller clamping elements can be used with higher pressure and thus more workpieces can be machined on one fixture. A single hydraulic cylinder, a complete group of cylinders or a complete hydraulic clamping fixture can be connected to the hydraulic intensifier. The integrated pilot-controlled check valve prevents a pressure drop in the high-pressure range on uncoupled pallets. Prerequisite is the use of leakage-free clamping elements.

Description:

An oscillating pump piston, that will be automatically reversed in the end positions by a hydraulically-operated valve, is installed in the intensifier. The ratio of the piston areas corresponds to the intensification ratio. For unhindered flow in the low-pressure range, the pump piston will be bypassed by means of a bypass-line. A pilot-controlled check valve shuts off the high pressure.
