SUTTNER ST-6 FLOW SWITCH 8GPM 4380 PSI

The ST-6 flow switch is a "normally open" flow switch, designed to be mounted in a high pressure water line. Inside the housing is a floating magnet which is aligned parallel with a reed switch. When the water flow is initiated, usually when the spray gun trigger is pulled, the water flow forces the magnetto move forward. Once in the correct position, the magnet pulls the thin reeds together, closing the circuit and allowing electrical continuity. When water flow ceases, usually when the trigger is released, a light spring returns the magnet to its original position. The reeds then pull apart and open the circuit, stopping electrical continuity.

Flow Switch Advantages:

• Mounts further downstream in pumping system than traditional vacuum switches, thereby minimizing potential leak points that can cause vacuum leaks to the pump
• Vacuum switches use rubber diaphragms that often rupture and cause vacuum leaks to the pump
• Flow switches operate at a variety of pressures
• Flow switches eliminate the need to restrict water flow to the pump, thereby prolonging pump life
• The reed switch is encased in a protective galss capsule with a sealed nitrogen atmosphere that eliminates exposure to corrosive cleaning chemicals

Reed Switch Adjustment: depending on the system flow, it is normal for the magnet position to vary. This variance may require adjustment of the reed switch upon initial installation, especially at lower flow rates. If the switch fails to close upon initial flow, simply loosen the adjustment screw and position switch so it properly opens/closes according to flow conditions.

Thank you for browsing our selection of pressure washers, steam cleaners and accessories.

We have the tools you need to effectively use and maintain your pressure washer.  Quick connect and rotating turbo nozzles are available in various sizes and configurations.  It's important to use the proper size nozzle for your pressure washer.  Nozzles are sized by looking at the PSI and GPM of your pressure washer.  Quick connect nozzles make it easy to change spray patterns or replace nozzles when they are bad while using the same spray wand.

Pressure washer hoses and hose reels will help you reach your work area, and specialized spray guns with different angles and lengths of wands will make certain jobs easier.

To keep your pressure washer working properly, routine parts and maintenance could be required.  Pressure washer pumps, unloaders, and motors should match the specifications of your particular machine.  Hot pressure washers and steam cleaners require additional components like burners, ignitors, and fuel pumps to allow them to heat the water.

There are a number of different accessories for your hot or cold pressure washer to clean different areas.  Surface cleaners are great for cleaning large areas like parking lots, gas stations, industrial facilities, and school yards.  Duct cleaners are designed to clean trash-chutes, vents, ducts, restaurant hoods, tanks and more. Wet sand blasters can be used on various surfaces to remove most coatings down to white metal, for graffiti cleaning, or paint surface preparation.
