Series 50 LW Model LW53

Peter Paul Series 50 LW Model LW53 Piped Valve

3-WAY NORMALLY CLOSED (piped) Valve

General purpose valves for pneumatic and hydraulic applications. The versatility of these valves is increased to include the handling of hot air, hot water, refrigerants, and many other media by the use of different seals. Air and other fluids are compatible with standard Buna seals. Hot water, steam, gasoline, oils, some hydraulic fluids, and many media require special seal materials.

  • General purpose valve with reduced power consumption.
  • Increased versatility.
  • For pneumatic and hydraulic applications.
  • Increased capability to handle hot air, water, and refrigerants.
  • High quality engineering.

PeterPaul has created this page for you so you can calculate the flow or Cv (flow coefficient) to make the relationship visible between the pressure drop (the difference in pressure between two points of a liquid/gas carrying network) and the flow rate.

The use of this flow coefficient (Cv) calculator offers a standard calculation to compare valve capacities and sizing for a wide range of applications. The type and sizing of a valve or regulator can have a large impact on the performance of the assembly for transferring gas or liquids in the system.

Our sales department is ready to answer questions and to solve your valve needs. Please feel free to call, chat or email us.
