Series 50SLLW Model SLLW53 - Piped Exhaust


3-Way Normally Closed Valve (Piped Exhaust)


General purpose for pneumatic applications. For use on air and common gases, compatible with standard Buna seals. Other media require special seal materials. The SLLW Valve is not a safety valve.

  • General purpose valve with greatly reduced power consumption.
  • Increased versatility.
  • NEMA 4 rating is standard with encapsulated coil.
  • High quality engineering.

Cv Flow Formulae

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.
