Key Considerations for Selection

When selecting a Rexroth valve, several factors should be considered to optimize performance and reliability:

• Application Requirement: Determine the specific needs of your system, including pressure and flow specifications, to select the appropriate type of valve. In some cases, consulting with application engineers can help in making the right decision.
• Environment: Evaluate environmental conditions such as temperature ranges, exposure to chemicals, humidity, and potential for corrosion to choose a valve material that can withstand them. For instance, stainless steel valves may be necessary in corrosive environments.
• Size and Flow Capacity: Select the valve that matches the system's required flow capacity for optimal performance. An under-sized valve can lead to inadequate flow rates, whereas an oversized valve can cause energy wastage and increased system costs.
• Control Type: Decide between manual, pneumatic, or electronic control based on the operational requirements. For automated systems, electronic control valves might be more suitable due to their ability to integrate with other systems.
• Pressure Ratings: Assess the maximum pressure the valve will encounter to ensure safety and functionality across the entire operational range. Utilizing valves that exceed the necessary ratings can provide a safety buffer against unexpected surges in pressure.
• Maintenance Needs: Consider the maintenance requirements and serviceability of the valve. Products designed for easier maintenance can lead to reduced downtime and labor costs in the long run.
