Why We Fit a VS350 Safety Valve to Our 350 Bar Pressure Cleaners

Learn why SPITWATER uses a VS350 safety valve in 350 bar pressure cleaners. Protecting people, parts, and performance. 

SPITWATER’s 350 bar pressure cleaners are designed for serious industrial use, where safety can’t be optional.

That’s why we fit a VS350 safety valve to all machines in this range. This valve actively monitors system pressure and adds critical protection against overpressure events, operator risk and component failure. 

The article covers: 
What is a VS350 Safety Valve?

The VS350 is a pressure-activated valve built for high-pressure water systems. It monitors line pressure and activates when a preset limit is exceeded.  

It works in coordination with the unloader or bypass valve and integrates directly into the machine's control logic. 

Why It’s Needed on 350 Bar Machines 
  1. Overpressure Protection

In 350 bar systems, pressure spikes can occur from: 

      • Kinked or blocked hoses 
      • Nozzle blockages 
      • Bypass valve failure 
      • Operator misuse 

The VS350 detects these faults and shuts down output before damage occurs. 

  1. Operator Safety

Uncontrolled spikes in pressure at 350 bar can lead to hose bursts, gun failures or injury. The VS350 helps maintain safe limits at all times - especially on multi-user or high-traffic sites. 

  1. Meets Industry Standards

Many industries, like mining, heavy transport, and food processing expect built-in safety measures for WHS and compliance. The VS350 helps meet these expectations and supports insurance and audit readiness.  

  1. Protects Components & Lowers Downtime

Overpressure can destroy: 

      • Pumps 
      • Valves 
      • Seals 
      • High-pressure lines 

Preventing this with a VS350 avoids costly repairs and supports SPITWATER’s long-life, low-maintenance promise.
