Control and pressure regulating valves are often installed with a high pressure drop across their elements. This high pressure drop can often lead to noise levels that are too high for nearby workers, or result in disturbance of local residences.
Flo-Dyne's diffuser insert silencer can offer a simple and effective way of reducing the noise from such valves without impacting on the flow capacity of the valve, or the size of the downstream piping, such that in many cases external acoustic cladding of the piping can be avoided.
Our diffuser silencer works by sharing the available pressure drop between the valve and the diffuser in a way that optimises the flow capacity, pressure loss and noise generation.
We can choose the correct hole sizing and spacing will enable the optimum noise reduction and pressure drop. as has been proven in thousands of silencer installations since our business began over 35 years ago.
Where space is restricted, or where special concerns arise we will examine the flow through our diffuser using Computerised Fluid Dynamics (CFD), which enable us to check the flow characteristics, flow impingements, as well as confirming the pressure loss, thereby delivering a low cost, low noise solution that avoids the expense of control valves with quiet trims, or the problems associated with metallic diffusing elements.
Whilst the diffuser is not part of the pressure retaining envelope the materials selection, welding processes, NDT and pressure testing are all the same as for your piping.
Our diffuser silencers have no replaceable parts, there is zero maintenance and they are a true a fit and forget solution.
