Fabri-Valve Figures C33 / C133 / F33 / F133 are bi-directional soft seated, slide gate valves designed for on/off service in heavy slurries. Specially designed body liners and constant contact seats minimize seat stress ensuring exceptional service life. Seats are self gasketing and are compatible with raised or flat faced, lined or unlined flanges. Figures C/F133 have a containment bonnet attached to the bottom flange to capture any discharge during cycling.
Unit of Measure


N/A Size Range

2" – 72": 200°F (93°C).
Higher temperature designs are available, Refer to section
“Pressure/Temperature Rating (Soft Components)”.
Flange Drilling
ANSI 125/150


N/A Every Fabri-Valve Figure C/F33 and C/F133 is tested prior to shipment. Testing includes a seat test and a cycling test to insure proper functioning of moving parts. Figures C133 and F133 are also body shell tested.* Additional testing is also available. Please let us know your requirements.
Shell test

  • Hydro test at 1.5 times the rated CWP – allowable leakage is zero
    Dual Resilient seat test
  • Hydro test at 15 psi (1 bar) and rated CWP – Zero water leakage

  • Pressure/Temperature Ratings

    N/A The tables listed in 'more images' are the maximum pressure/temperature ratings for the metallic components only. When checking pressure/temperature ratings, check the temperature rating and chemical compatibility of the packing material, and if applicable, the resilient seat material. In a majority of designs, the temperature limit or the chemical compatibility of the seat and/or packing material determines the practical pressure/temperature limitations.

    Flow Coefficients

    N/A The Cv values in 'more images' represent U.S. gallons per minute 60°F water through a 100% open valve at a pressure drop of 1 psi. The metric equivalent, Kv, is the flow of water at +16°C through the valve in cubic meters per hour at a pressure drop of 1 kg/cm2. To convert Cv to Kv, multiply the Cv by 0.8569.
