“PD” - General Purpose / NEMA 4, 4X / Explosion Proof

CONSTRUCTION:
Housing - Clear High-Strength Polycarbonate

APPLICATION:
Visual indication that valve is Open / Closed

OPERATION:
When the valve is in the closed position, a ferromagnetic “target” attached to the valve’s piston, lifts a green colored magnet into the adapter hiding it from view. When the valve is energized, (open position), the magnet drops down to a visible position.

Position Indicators for Normally Closed Valve Only
Available on Type A, S, L, K, W & G Valves
