Suttner ST-7 Pressure Washer Flow Switch – 5000 PSI, 12 GPM | 200007500

$89.99

The Suttner ST-7 Flow Switch, part #200007500, provides flow detection for commercial pressure washers and high-pressure cleaning systems. Rated for up to 5,000 PSI and 12 GPM, it features a 1.2 GPM switching point and standard 3/8" female pipe thread connections.

Built for demanding equipment applications, the ST-7 uses a durable microswitch instead of a reed switch for improved resistance to shock and machine vibration. Its spring-assisted magnet assembly allows installation in any orientation, while a 47" wire lead provides flexibility when connecting it to your equipment’s control circuit.

Features and Benefits

  • Reliable flow detection: A 1.2 GPM switching point supports flow-dependent equipment controls.

  • Vibration-resistant microswitch: Designed to withstand the shock and vibration encountered in commercial pressure-washing equipment.

  • 5,000 PSI maximum operating pressure: Suitable for high-pressure systems within the switch’s specified ratings.

  • Up to 12 GPM flow capacity: Accommodates a range of commercial pressure washer applications.

  • IP65-rated enclosure: Protects against dust ingress and low-pressure water jets.

  • Flexible mounting: Spring-assisted magnet assembly permits horizontal, vertical, or angled installation.

  • Standard plumbing connections: 3/8" FPT inlet and outlet ports simplify integration into compatible systems.
