Is the FPSB Hydraulic System Throttle Valve suitable for bidirectional flow and what is its operating temperature range?

Yes. The FPSB Hydraulic System Throttle Valve is engineered for bidirectional flow (A → A1, A1 → A) and operates reliably in temperatures from -20°C to +90°C.

How do I adjust the FPSB Hydraulic System Throttle Valve for precise flow control in both A → A1 and A1 → A directions?

To adjust the FPSB Hydraulic System Throttle Valve for precise flow control in both A → A1 and A1 → A directions, follow these steps: 1. Identify flow direction and ensure system pressure is within safe limits. 2. For flow A → A1: rotate the solid steel adjustment knob clockwise to reduce flow (increase restriction) and counterclockwise to increase flow. Make small incremental turns and allow the system to stabilize between adjustments. 3. For flow A1 → A: the valve is bidirectional—use the same knob operation (clockwise to reduce flow, counterclockwise to increase). Verify flow response in this direction because load and return conditions may differ. 4. Use gradual adjustments and monitor flow rate, actuator speed or pressure drop to achieve the required setting. Lock or note the knob position once desired flow is obtained. 5. Maintain the valve: ensure NBR seals and galvanized body are clean and undamaged; operate within -20°C to +90°C for reliable performance. Safety: depressurize or follow site safety procedures before handling.
