- Suitable for Liquid, Gas, and Vapor Service
- In liquid service, results are noise reduction and cavitation reduction.
- In gas and vapor service, results are noise reduction, valve outlet velocity reduction, and valve size reduction.
- Pressure reduction can be in excess of 100 psi per plate, a five-stage silencer design allows for pressure drops greater than 500 psi.
Type 3381 Downstream Silencer is offered in several designs:
- Wafer single plate - placed before or after pipeline expansion
- Two wafer single plates - placed before and after pipeline expansion
- Flanged single plate - placed before or after pipeline expansion
- Flanged single plate with multiple stages - placed before or after pipeline expansion
- Multi-stage plates in body housing - placed between valve outlet and expanded downstream pipe
