What is the recommended set pressure for the Brake Valve, VODE Type relative to actuator load pressure?

Brake Valve, VODE Type — Recommended set pressure The set pressure of the Brake Valve, VODE Type should be maintained at approximately 30% above the actuator’s load-induced pressure. This ensures reliable control and safe, smooth descent under heavy loads while allowing the valve’s adjustable opening screw (secured with a counter nut) to fine-tune performance. Note: the standard check valve opening pressure is 0.5 bar.

Can the Brake Valve, VODE Type be used with actuators operating above +100°C, and what sealing materials are recommended for higher temperatures?

Brake Valve, VODE Type cannot be specified for continuous operation above +100°C based on the provided description: its stated operating temperature range is -20°C to +100°C. Using it above +100°C risks seal failure, accelerated wear and loss of reliable control. For applications above +100°C, replace the standard NBR seals with higher-temperature materials. Recommended sealing materials: - FKM (Viton): serviceable up to ~+200°C short-term, good chemical resistance. - PTFE (Teflon): excellent high-temperature capability (continuous use well above +200°C), low friction, chemical inertness; may require special backup rings. - EPDM: usable up to ~+150°C in some grades, good for steam and hot water but poorer oil resistance than NBR. Before modifying or specifying seals, confirm compatibility with hydraulic fluid, pressure and dynamic conditions, and consult the manufacturer to ensure proper seal design and qualification for >+100°C operation.

Additional information

Material	CS – steel (cast iron)

VODE valves are designed for hydraulic systems as reliable control and blocking components for double-acting actuators, ensuring precise and safe operation even under heavy loads. They enable smooth and controlled actuator descent, with the opening pressure easily adjustable via screws using an Allen key and secured with a counter nut. For optimal performance, the set pressure should remain 30% higher than the load-induced pressure of the actuator, while the standard check valve opening pressure is 0.5 bar. Manufactured from durable galvanized steel and sealed with high-quality NBR, these valves guarantee long-lasting resistance to wear, corrosion, and demanding working conditions. With an operating temperature range from -20°C to +100°C and practical mounting holes for easy installation, VODE valves combine robust construction with user-friendly adjustment, making them an excellent choice for applications requiring reliability, precision, and efficiency in hydraulic control.
