Lift Check Valves
Check Valves
Specifications
LC Series lift check valve’s all-metal design is suitable for extreme temperatures found in power, oil & gas, chemical, petrochemical, pulp & paper, and laboratory applications. LC Series valves use gravity and back pressure to prevent reverse flow to less than 0.1% of forward flow. Applications include:
- Grab samples
- Industrial engines
- Separators
- Nozzles
- Emissions analyzers
