Q: What is the primary function of a "Pressure Stop Valve" (DAW series)?
A: The DAW series is a proportional pressure stop valve. Its core function is to act as an electrically controlled, proportional shut-off valve for a hydraulic pressure line. It can block flow completely (zero leakage) or open proportionally to allow controlled flow, all while maintaining a specified maximum pressure on the downstream (A) port. It is often used to isolate or control a branch circuit.
Q: How does this valve differ from a standard proportional relief valve (DBW series)?
A: While both are proportionally controlled, their functions and porting differ: A DBW relief valve is a 2-port valve (P to T) that opens to tank to limit pressure. A DAW pressure stop valve is a 3-port valve (P, A, T). In its de-energized state, it typically blocks flow from P to A and connects A to T (drains the downstream circuit). When energized, it proportionally connects P to A (supplying pressure) and blocks A to T, acting as a pressure-controlled shut-off valve.
Q: What does the "FS" prefix in the solenoid code (FS6EG24N9K4) signify?
A: The "FS" is a variant code for the proportional solenoid. It may indicate a specific coil winding, force characteristic, connector type, or the inclusion of integrated electronics (like a plug-in amplifier). This is a specific version of the standard 6EG24N9K4 solenoid. The exact technical difference (e.g., different spool force) must be verified in the component's detailed datasheet to ensure compatibility with the intended control system.
Q: This valve has a 30mm nominal size. What are the main considerations for installation?
A: The large size (30mm) allows for high flow (up to ~200 L/min). Key installation considerations are: 1) Manifold Design: The mounting cavity must precisely match the cartridge dimensions (ISO 7368). 2) Port Sizing: Ensure piping matches the large 1-1/4" UNF ports to avoid flow restriction. 3) Drain Connection: The external pilot drain (Y port) is critical and must be connected directly to tank with zero backpressure via a sufficiently large line. 4) Weight/Support: The cartridge and associated piping are heavy; proper mechanical support is needed.
Q: Can this valve be used for emergency system shutdown?
A: Yes, its fail-safe function makes it suitable for this role. Typically, in a safety shutdown scenario, the valve's solenoid would be de-energized (e.g., via an emergency stop circuit). This causes the valve to immediately block the pressure inlet (P) and connect the downstream circuit (A) to tank (T), safely depressurizing and isolating the controlled section of the system. Its proportional nature also allows for a controlled ramp-down if needed.
