Sky Vent Silencing
Valves within a sky vent system bypass steam around the turbine to ensure the unit does not come up to temperature too quickly. 

Valves within a sky vent system bypass steam around the turbine to ensure the unit does not come up to temperature too quickly. 

The large pressure differential across the sky vent valve can cause high noise levels that need to be attenuated. Additionally, high temperatures and valve leakage in a sky vent application can reduce plant load and efficiency if the valves are degraded. 

Our sky vent silencing solution uses a noise attenuating control valve and diffuser combination to minimize noise generation.

The pressure drop is split between the valve and a downstream diffuser or silencer to reduce noise. High alloy materials and thermally compensated trim designs are used to maintain tight shutoff and increase the lifespan of valves.
