Product catalog summary
Applications
RICKMEIER DBV40-pressure relief valves are used in oil hydraulics, lubrication technology, and with various oils or lubricants. They are designed for pressure relief but are not classified as safety valves according to DIN 3320. Common industrial applications include general machine building, automotive, construction, mining, and the chemical industry.
Technical Specifications
The valves feature a nominal size of DN40, a maximum flow rate of 400 L/min, and a design pressure of 100 bar. They are globe valves, hydraulically precontrolled, and can be installed in any position. The set pressure range is between 2 to 40 bar.
Product Description and Function
DBV40 valves are hydraulically precontrolled with metric SAE connections. They consist of a main valve body, piston, orifice, and compression spring. The valve operates by balancing pressure between the valve inlet and spring chamber, with adjustments made via a regulating spindle.
Flow Media
Suitable flow media include gear lubricant oil, hydraulic fluid, and crankcase oil. The medium should be clean, non-corrosive, and free from hard constituents. Special measures are required for use above 80°C.
Characteristics
Valve characteristics are depicted in diagrams showing the relationship between pressure and flow. The standard valve has internal control oil drainage, and the pressure increase varies with the kinematic viscosity of the fluid.
Identification and Type Code
DBV40 valves are identified by a specific code detailing the piston size, pressure control, connection type, and materials used.
Variations
Variations include fixed non-adjustable overload safety valves and pressure control valves with external control options. Set pressure ranges vary from 2 to 40 bar depending on the application.
Standard Versions and Variations
This section outlines the standard and alternative materials used in valve construction, including body, piston, and springs. Standard materials include EN-GJS-400-15 (GGG-40) for the body and hardened steel for the piston, with alternatives like CrNi-steel and FPM (Viton) available for specific variations.
Specifications
The document details various valve configurations, such as the DBV40 pressure control valve with a piston pilot unit for pipeless attachment, suitable for continuous pressure regulation with set pressure ranges of 2-8 bar, 6-12 bar, and 10-40 bar. Another example is the pressure stage control valve used in marine gearboxes to limit pilot and control pressures, with ranges of 10-40 bar for control pressure and 2-20 bar for pilot pressure.
Procedures
Figures illustrate the pressure-time diagram for the startup process of a multidisc clutch and the operation of a pressure stage control valve. The diagrams provide insights into the switching process and pressure regulation.
Maintenance
RICKMEIER pressure relief valves are generally maintenance-free if operated within permissible limits. If a valve becomes unserviceable due to wear, it must be replaced, as installing spare parts does not restore original safety.
Applications
Valves are used for pressure limitation and regulation in various systems, including marine gearboxes and continuous flow systems. Specific applications and pressure ranges are provided for different valve types.
Control and Operation
Directional control valves can be operated electrically (24V DC) or pneumatically, with specific configurations for internal and external pilot units.
