W: Seal Material - Fluorocarbon Rubber (V)
N: Standard knob adjustment (non-locking)
IV. Operating Principle (Kick-down Characteristic)
Similar to an electrical circuit breaker:
Inlet (Port 1) pressure exceeds set value → Valve fully opens
Remains fully open → Fluid flows freely from Port 1 to Port 2 (tank)
Reset condition: Flow from Port 1 to Port 2 stops, and Port 2 pressure ≥ Port 1 pressure
