IMI Buschjost leads the industry with a wide range of indirect acting solenoid valves.

Water hammer, also called fluid hammer or hydraulic shock, creates a pressure spike in a pipe system that can damage seals, gauges, pipes and fittings – virtually anything upstream. IMI Buschjost addresses the problem at the source – the valve. Our superior solenoid valves are proven to reduce pressure spikes by more than 80% compared to competitor equivalents.

Benefits of IMI Buschjost valves:

  • Reduce system costs by eliminating:
    • Pressure regulators
    • Shock absorbers
    • Check valves
    • Accumulators
  • Helps optimise total cost of ownership (TCO)


  • 2/2-Way valves – normally closed and open
  • Brass and stainless steel
  • International approvals available
  • Compact design
  • Choice of seal materials available
  • Pressure range: 0.1 to 16 bar (232 psi)
  • 1/4 … 2 (ISO G/NPT) port size options
  • Many technical options available
  • Patented Click-on® coil
  • Sealed core tube

Rapid Close – Reduced Water Hammer

Rapid closing of the valve is required for safe and effective operations in systems that typically use these 2-way valves. The IMI Buschjost valves have a propriety internal design that lets them close smoothly and gently, reducing pressure while still maintaining closing speed. The result is the valves close in a quarter of a second but with just a fraction (one-fifth) of the pressure surge typical of other similar valves.

The Click-on® solenoid system is available for all standard voltages and offers users a low maintenance solution as the solenoids are quick and easy to replace without the need for any tools.

Successful in the market for more than 80 years, system designers have been selecting these solenoids for years due to their excellent performance attributes and robust design.

Our strengths:

  • In-depth technical knowledge
  • Large stock holding
  • Personal service
  • Fast, reliable and efficient service
