Shop DH55 Main Relief Valve | OEM aftermarket new

The DH55 Main Relief Valve is designed to regulate the pressure in a hydraulic system by diverting excess fluid flow back to the reservoir.

It is typically installed in the main pressure line and acts as a safety mechanism, preventing pressure from exceeding predetermined limits. This ensures the system operates optimally while safeguarding against overpressure situations.

One of the key specifications of the DH55 Main Relief Valve is its pressure rating. It is engineered to handle a specific pressure range, typically up to a certain maximum pressure, ensuring that the valve can effectively manage the system pressure within these limits. The pressure rating of the DH55 Main Relief Valve is often mentioned by the manufacturer and is an essential consideration when selecting the appropriate valve for a given application.

Flow capacity is another critical specification of the DH55 Main Relief Valve. It determines the amount of fluid that can pass through the valve per unit of time. The flow capacity is typically expressed in gallons per minute (GPM) or liters per minute (LPM) and depends on factors such as valve size, design, and internal geometry. A higher flow capacity allows for greater fluid throughput, making the valve suitable for applications with larger hydraulic systems or high flow rates.

The DH55 Main Relief Valve features an adjustable pressure setting. This means that the valve can be calibrated to open at a specific pressure level, allowing for customization based on the requirements of the hydraulic system. The adjustable pressure setting provides flexibility and enables precise control over the system pressure, ensuring optimal performance and protection.

In terms of construction, the DH55 Main Relief Valve is typically made from high-quality materials such as durable metals or alloys.

These materials are chosen for their strength, corrosion resistance, and longevity, ensuring the valve can withstand the demands of industrial environments and maintain its performance over time.

The valve is often designed with a direct-acting or pilot-operated mechanism. In a direct-acting relief valve, the force exerted by the system pressure directly controls the valve's opening and closing. Pilot-operated relief valves, on the other hand, use a separate pilot pressure to control the main valve, providing additional control and stability in certain applications.

Furthermore, the DH55 Main Relief Valve may incorporate additional features such as temperature compensation, pressure gauges, or manual overrides. These features enhance the functionality and usability of the valve, allowing for precise monitoring and control of the hydraulic system.
