1-9000 Limiphon Multi-path labirynth valves

Parcol

High pressure drops cause acoustic porblems and cavitation in liquid services. LIMIPHON's trim divides flow into many streams to minimize its energy and reduce noise, cavitation, vibrations and erosion.

Specifically studied for severe service applications, LIMIPHON valves were designed and built by Parcol in 1971.

Based on the concept of multi-path and multi-stage labyrinths (velocity controlled trim), LIMIPHON trim divides flow into many streams to minimize the energy levels and it is the ideal solution for all those applications where high pressure drops are the main cause of noise, cavitation, vibrations and erosions.

Typical services where LIMIPHON valves are indicated:
- Compressor recycle (antisurge )
- Blowdown to vent or flare
- Natural gas pressure reducing stations (anti-icing effect)
- Steam turbine by-pass stations
- Feedpump recirculation
- Feedwater start-up
- Pump test loops
- Superheater/reheater attemperator spray
Features
- nominal diameter: 1 to 36”
- nominal pressure: up to 400 bar
- angle, straight or "Z" type design
- Variable flow
- Process connection flange, welding ends
- Sensor / wetted parts material 316/316L, carbon steel
- Seals graphite, PTFE
