HAWE HRP Hydraulic Check Valve, Genuine from Germany

HAWE HRP Hydraulic Check Valve, Genuine from GermanyHAWE HRP hydraulic one-way valve is used to close the oil circuit of the hydraulic actuator when the slide valve directional valve leaks. Or used as a hydraulic operated drain valve or unloading valve. To alleviate the unloading impact during high pressure and high flow, the HRP type hydraulic control one-way valve can be optionally equipped with a pre unloading structure.

The HAWE HRP type hydraulic control check valve controls the back of the slide valve to unload through the leakage port, and the pressure of the return port B has little effect on the pressure of the valve. As an option, the shut-off valve can be controlled arbitrarily through a plate type solenoid valve with the help of the load pressure of the actuator.

HAWE hydraulic control one-way valve HRP can be used as an option to control the shut-off valve arbitrarily through a plate type solenoid valve with the help of the load pressure of the actuator. Compressed air enters from the corpse's mouth, overcoming the spring force and friction force to open the one-way valve port, and compressed air flows from P to A. When there is no compressed air at P port, it is under the action of spring force and residual air force at A port (chamber); The valve port is in a closed state, preventing airflow from A to P.

The directional control valve of Hawei HRP 7 V hydraulic control check valve can only flow in one direction and cannot flow in the opposite direction. Its working principle is the same as that of hydraulic check valve. To alleviate the unloading impact during high pressure and high flow, the HRP valve can be optionally equipped with a pre unloading structure. The HAWE one-way valve from Germany is used in situations where airflow is not allowed to flow in the opposite direction. For example, when an air compressor is inflating a gas tank, a one-way valve is installed between the air compressor and the gas tank. When the air compressor stops working, it can prevent compressed air from the gas tank from flowing back to the air compressor.

One way valves are used in hydraulic systems to prevent reverse flow of oil, or in pneumatic systems to prevent reverse flow of compressed air. There are two types of one-way valves: straight through and right angle. The straight through one-way valve is installed on the pipeline with threaded connections. There are three forms of right angle one-way valves: threaded connection, plate connection, and flange connection.

When installing a one-way valve, special attention should be paid to the direction of medium flow. The normal flow direction of the medium should be consistent with the arrow direction indicated on the valve body, otherwise it will cut off the normal flow of the medium. The bottom valve should be installed at the bottom of the water pump suction pipeline.

When the HAWE check valve from Germany is closed, water hammer pressure will be generated in the pipeline, which can cause serious damage to the valve, pipeline or equipment, especially for large mouth pipelines or high-pressure pipelines. Therefore, the selection of check valves should be highly cautious.

Structure and function of HAWE one-way valve from Germany

A valve that opens or closes by the flow and force of the medium to prevent reverse flow of the medium is called a one-way valve. One way valves belong to the category of automatic valves, mainly used on pipelines with one-way flow of media, allowing only one direction of media flow to prevent accidents.

The function of a one-way valve is to allow the medium to flow in only one direction and prevent the flow in the opposite direction. Usually, this type of valve works automatically, and under the pressure of fluid flowing in one direction, the valve disc opens; When the fluid flows in the opposite direction, the pressure of the fluid and the self weight of the valve disc act on the valve seat, thereby cutting off the flow.

HAWE check valves from Germany can be divided into three types based on their structure: lift check valves, swing check valves, and butterfly check valves. Lift type one-way valves can be divided into two types: vertical and horizontal. Rotary check valves are divided into three types: single valve, double valve, and multi valve. Butterfly check valve is a straight through type, and the above types of check valves can be divided into three connection forms: threaded connection, flange connection, and welding.
