The HAWE VALVE PMVP 4-43/G 24 is a proportional relief valve produced by HAWE Hydraulik SE in Germany. Below is a detailed introduction to this product:
I. Product Overview
• Brand and Model: HAWE VALVE PMVP 4-43/G 24, belonging to the PMVP series of proportional relief valves from HAWE Hydraulik SE.
• Function: This valve can serve as a safety valve to regulate system pressure in hydraulic circuits. It offers excellent stability and adjustment performance, along with a long service life and a high available power ratio.
II. Technical Features
• Control Method: The control oil is externally controlled and separated from the main oil circuit, with a pressure difference of approximately 200 bar. This design enhances the safety of valve operation, ensuring the protection of personnel and equipment.
• Adjustment Performance: The valve is flexible in use, with a sensitive valve body and rapid response. Through the flow adjustment screw, the valve can be set to a lower value in the event of a power failure or when the system is at low pressure.
• Pressure Range: The pressure can be adjusted up to 700 bar, making it suitable for high-pressure systems. Additionally, for extremely low-pressure applications (0 to 5 bar), it maintains adjustability with the aid of control pressure.
• Structural Characteristics: The PMVP pressure-reducing valve can be used as a single valve with pipeline connections or as a plate-mounted valve. It features a compact structure, small size, high-pressure resistance, and leak-free operation, ensuring a long service life.
III. Application Scenarios
• High-Pressure Systems: It is used to extend the service life of pressure control devices, particularly in applications requiring prolonged pressure maintenance without control oil loss.
• Extremely Low-Pressure Applications: In extremely low-pressure scenarios, this valve maintains adjustability with the aid of control pressure, meeting specific hydraulic requirements.
• Main Circuit Applications: In the main circuit of high-pressure systems, this valve can maintain pressure for extended periods without losing control oil, ensuring stable system operation.
IV. Product Advantages
• Durability: HAWE Hydraulik SE's products are renowned for their high quality and long service life, and this valve is no exception.
• Safety and Reliability: The explosion-proof proportional relief valve design enhances the safety and reliability of valve operation.
• Flexible Adjustment: The valve offers flexible adjustment performance, allowing for precise pressure regulation based on actual needs.
