All About Soft Start Dump Valves!

Prioritising safety...

it’s important to think about adding additional safety options to your systems to prevent injury to operators and damage to downstream equipment.

Soft start dump valves provide a soft start function that allows for a controlled increase of downstream pressure on initial startup before fully opening to deliver line pressure. As well as a dump function to ensure the system pressure is exhausted quickly when required.

What are the benefits of soft start dump valves?

  • Prevent injury to workers
  • Prevent damage & increase longevity of machinery
  • Prevent your systems from being out of sequence after an emergency stop

It is important to consider installing these with your Filter Regulator Lubricator system

So how do they work?

In a system that doesn’t have a soft-start dump valve, upon initial start-up when line pressure is delivered, cylinders can jolt open and slam into position.

This can cause injury to workers nearby, as well as damage your equipment.

When a soft start dump valve is installed, the pressure within it gradually increases to approximately 50%, before opening completely. This results in a smoother opening, avoiding unnecessary wear and tear, and improving overall safety.

During planned maintenance or an emergency shutdown, it is important for removing line pressure downstream, to reduce the chance of operator injury or damage to tools and equipment. That’s where the dump function comes in. When the valve becomes de-energised it isolates and quickly removes downstream pressure to atmosphere.

This rapid evacuation of air can be noisy too, so it is recommended to fit a high flow silencer, such as the Quietaire.

What should happen when there’s an emergency?

Emergency Stop – Hold

Dump – Release

Soft Start – Gradually increase

Soft start dump valves can be placed inline along with your Filter/Regulator/Lubricator components or can be used as a stand-alone unit anywhere in your system.
