⛳Pressure-limiting valves and relief valves are types of pressure valves. Pressure-limiting valves safeguard the system against excessive system pressure or limit the operating pressure. Sequence valves generate a constant pressure difference between the
inlet and outlet flow.
Pressure relief valves are widely used in scenarios where system pressure needs to be prevented from exceeding safe limits, including industrial automation (pneumatic systems, injection molding machines), energy sector (oil, natural gas, nuclear energy), building water supply (high-rise water supply, fire protection), heavy machinery (excavator, crane hydraulic circuits), and household appliances (water heaters). Their core function is to safely release excess pressure and protect equipment, personnel, and the environment from overpressure damage or explosion.

Pump elements type MPE and PE for radial piston pumps
The pump elements type MPE and PE deliver lubricating hydraulic = uids while
simultaneously generating a counter-pressure opposing the load resistance of a
connected consumer.
The pump elements type MPE and PE are the cornerstone of all HAWE radial
piston pumps.
High-pressure pumps for various requirements can be constructed using pump
elements and suitable drive components.

Description: Pump piston plunger
Design: Valve-controlled pump piston plunger
Installation position: As desired
The suction valve inlet of the pump element must be entirely below the oil level to prevent any air being drawn in. The piston and roller bearings must be fully immersed under the oil level during continuous operation to ensure continuous lubrication.
Material: Steel; hardened, ground functional inner parts
