HAWEジャパン List of Products and Services

- This is a valve that integrates a low-pressure unloading valve and a high-pressure relief valve, which unloads when the low-pressure side of a multi-flow pump or a low/high-pressure pump reaches the set pressure. - Compared to assembling the relief valve and unloading valve separately, it is more cost-effective, smaller and lighter, and requires less piping. - When a pump manufactures an oil-immersed hydraulic unit inside a tank, installing this valve on the upper cover allows the piping inside the tank to be consolidated to this valve, eliminating the need for fittings and manifold blocks.

● It is a responsive direct-acting pressure control valve (including sequence valves). ● It has a unique damping mechanism built in to protect the valve seat, making it durable and capable of handling sudden pressure fluctuations at high pressures without issues. ● It is compact and lightweight. ● The set pressure can be fixed with a lock nut.

It is used when you want to limit the pressure of a part of the hydraulic circuit to a pressure lower than that of the main circuit. A pressure reducing valve that can maintain a constant pressure on the secondary side against pressure changes in the primary pressure. 【Features】 - The ADM type is equipped with an overload correction function that relieves pressure when the secondary side exceeds the set pressure.

It is used when you want to limit the pressure of a part of the hydraulic circuit to a pressure lower than that of the main circuit. It is a reducing valve that can maintain the pressure on the secondary side constant against pressure changes on the primary side.

This valve is a direct-acting pressure reducing valve, and while conventional balanced piston type pressure reducing valves require a drain port to escape internal leaks, this valve has no drain port due to its non-leak design.

This pressure relief valve is equipped with an override compensation function, which allows it to operate like a pressure control valve when the secondary side pressure exceeds the set value due to external forces. All specifications are non-leak in the closed state.

This valve is a direct-acting pressure control valve that provides pressure proportional to an electrical signal. It is compact and can handle high pressure. It is resistant to surge pressure and has high durability. A pressure reducing valve is incorporated into the proportional control section, resulting in a small internal leakage amount and excellent precision.

This valve is a balance piston type and is used to electrically remotely control the system pressure within a hydraulic device. It is a reducing valve that can proportionally adjust the pilot pressure according to the electrical command signal, reducing the primary pressure to a stable secondary pressure for supply. 【Features】 - Flow in the reverse direction against control can be up to 50% of Qmax. - It also has an overload compensation function, operating as a relief valve when the secondary pressure exceeds the set value due to external forces.

This valve is a balance piston type and is used for electrically remote controlling the system pressure within hydraulic devices. There are three types: relief valve, sequence valve, and pressure reducing valve.

- The mounting part has a double structure, making it easy to process the manifold, eliminating the influence of mounting distortion, and preventing damage to the manifold holes even when reassembling. - The dimensions of the mounting part are short, resulting in a smaller manifold, which simplifies hole processing and reduces manufacturing costs. - It is ideal for high pressure of 30 to 50 MPa, compact and lightweight, and suitable for downsizing manifolds and hydraulic units while reducing costs. 【Features】 - Used to control pressure within hydraulic systems. - Available in two types: relief valves and sequence valves.

A reducing valve has the function of maintaining a constant outlet pressure when the inlet pressure becomes high within a hydraulic circuit. These valves are typically used when it is necessary to supply a low and constant pressure to a secondary circuit from a primary circuit that has high and variable pressure levels. They are designed for flow supply to control circuits with low flow requirements. By design, there is always a leak, which needs to be returned to the tank through the depressurized line. Reverse flow direction is possible up to about 30% of Qmax. A bypass check valve is required for higher pressure reverse flow. These reducing valves are equipped with an override compensation function, which allows them to function like pressure control valves when the pressure on the secondary side exceeds the set pressure due to external forces, etc.

These valves block the flow path to the actuator downstream when the pressure at port B of the actuator reaches the set pressure. At this time, there is no leakage at all. When the pressure at port A falls below the set value, this valve opens the flow path again. The advantage of the cartridge-type valve CDSV is that it is easy to process the mounting holes (refer to dimensions). This type is used for the protection of pressure gauges.

- Our multi-flow pump can be combined with a seat-type switching valve to form a synchronization circuit. - It maintains a constant speed for reversing devices, swinging devices, and long crane arms where the load fluctuates positively and negatively.

- Compatible with cartridge, piping, and manifold installation. - There are specifications equipped with return pressure compensation and spring chamber pressure relief mechanisms. - There is also a type that can be directly mounted on the actuator.

This valve is a balance piston type and is used to electrically remotely control the system pressure within a hydraulic device. It is a reducing valve that can proportionally adjust the pilot pressure in response to an electrical command signal, reducing the primary pressure to a stable secondary pressure for supply. 【Features】 - Flow in the reverse direction against control can be up to 50% of Qmax. - It also has an overload compensation function, operating as a relief valve when the secondary pressure exceeds the set value due to external forces.

There is also a pressure switch that can simultaneously set and switch pressure with a single adjustment function.

The top model ePrAX max is an electric hydraulic drive system device (including cylinders). Its main feature is a structure that allows for easy mechanical and electrical connections. Speed control is performed for each actuator via a drive regulator. The static and dynamic servo motors control the speed of the approach stroke and the bending stroke. By using temporarily stored drop energy for the return stroke, it leads to dynamic operation and significant energy reduction. This enables efficient operation, eliminating the need for additional equipment such as cooling devices. The required amount of hydraulic oil is only 10% compared to conventional products.

HAWE Hydraulik hydraulic equipment uses steel materials for its components, allowing it to be used in various harsh environments. The adoption of a modular system results in a hydraulic system that is highly durable and easy to maintain. The small manufacturing tolerances and thorough quality inspections guarantee high quality for our customers. This is a point we would like to convey to your drilling machinery and your customers.

By reducing the weight and space of hydraulic system products, the fuel efficiency of garbage trucks is improved, and installation and maintenance work becomes easier.

The arrangement of the vehicle control unit, hydraulic pump, directional control spool valve, and load holding valve enables highly sensitive and optimal control, allowing for a system that minimizes vibrations without being affected by the load, composed of HAWE Hydraulik's hydraulic equipment components.

The monoblock SMBF for forklift control is a valve block designed based on customer requirements. The functions added for the lifting and all operations of the forks are proportionally controlled. This enables very high sensitivity and smooth sequential operations, unaffected by the load, thus adequately accommodating the movements of the forks, which require high reproducibility in automated processes and operator usability.
