N/A Size Range
1.5"-96"
Pressure Rating
1.5" - 24": 150 psi (10.3 bar) CWP (cold working pressure)
25" - 48": Designs available in 50 psi (3.5 bar), 100 psi (6.9 bar) or 150 psi (10.3 bar) CWP
Larger than 48": Manufactured to customer specification
Temperature Rating
1.5" -48" 450°F (232°C).
Service temperatures above 400°F (204°C) require high temperature fasteners. Specify service temperature on paperwork. Consult factory for sizes larger than 48" (DN 1200) and for service temperatures up to 1500°F (816°C).
Flange Drilling
ANSI 125/150

N/A Every Fabri-Valve Figure C/F37 valve is fully tested prior to shipment.
Testing includes a body shell test, a seat test and a cycling test to insure proper functioning of moving parts. Additional testing is also available. Please let us know your requirements.
Standard Shell test:

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 knife gate valve designs, the temperature limit or the chemical compatibility of the seat and/or packing material determines the practical pressure/temperature limitations.

* “R” Series valves have external, non-wetted, carbon steel components.
Standard “R” Series valves are limited to 700°F (371°C); however alternate “R” Series constructions are available to 1000°F (538°C)

N/A Metal Seat

N/A Metal seated knife gate valves are seat tested at 40 psid (2.8 bar) in the preferred flow direction. When pressure falls below the 40 psid (2.8 bar) test pressure, less force is pushing the gate into the seat, which may result in additional seat leakage. When improved low-pressure shutoff performance is required, optional chest buttons and/or centerline buttons should be specified.
