 Options & Accessories:
FNW Valve Company offers many options and modifications for their cast steel valves. These include, but are not limited to:
  • By-Passes
    A By-Pass is primarily used to equalize pressure between the valve inlet and outlet before opening the main valve. Equalizing pressure makes opening the main valve easier, especially on valves with a high differential pressure.
  • Actuation & Accessories
    FNW Valve can supply an assortment of actuation types and accessories including ratchets, chain wheels, square drive nuts, gear-operators, pneumatic and hydraulic cylinders, and motor operators.
  • Packing Options
    Different applications can have different needs. FNW Valve offers packing materials for various pH and temperature requirements.
  • Stem Extensions & Floor Stands
    For remote applications, custom stem extensions and non-rising stem (NRS) adapters are available in carbon and stainless steel. Also available are floor stands made to order to your specifications.
