FAQ:
Q: What is the main difference between this valve and the previous NG25 models?
A: This valve (R900769053) is an NG32 size valve with a rated flow of 520 L/min, making it significantly larger and higher-flow than the NG25 (325 L/min) models. It is designed for heavy-duty industrial applications requiring high flow rates.
Q: How does the pilot oil configuration work?
A: This valve (/6EG24N9K31) uses internal pilot oil supply (from main P port) and external pilot oil return (to Y port). You must connect the Y port directly to the tank with a dedicated line (max backpressure 30 bar). This configuration simplifies the external pilot supply but requires careful management of the external drain line.
Q: Why choose the /A1 version?
A: The /A1 suffix (±10 V voltage input) is ideal for high-precision control systems (e.g., servo controllers, motion controllers) where fine resolution and fast signal response are required. It is commonly used in closed-loop systems with position or velocity feedback.
Q: What is the role of the /D3 pressure reducing valve?
A: The /D3 option is an integrated, fixed-setting pressure reducing valve (ZDR 6). It ensures the pilot stage receives a stable, reduced pressure (typically around 40 bar), protecting the sensitive pilot valve from high and fluctuating main system pressures. This is critical for consistent valve performance.
Q: What is the critical installation note?
A: Ensure the external pilot drain (Y port) is connected directly to the tank with minimal backpressure (max 30 bar). High backpressure on Y can cause the pilot valve to malfunction. Since this valve uses internal pilot supply, ensure your main system pressure is within the operating range (100–350 bar) or provide an external pressure-reducing valve if needed. Maintain high oil cleanliness (recommended NAS 1638 Class 8 or ISO 4406 20/18/15).
