F-Class Valve NPS ½ to NPS 6 (DN15 to DN150) -58ºF/ -50ºC to 1100ºF/593ºC Class 150, 300 and 600 Extremely Fast Delivery (Including Exotic Materials)
what makes this valve different?
TRADITIONAL BALL VALVE DESIGNS Combine Use ASME the two B16.34 ASME Code Code to calculate requirements the minimum into wall one bolting thickness common requirements part Therefore, ASME Only wetted minimum ASME only the areas minimum wetted wall need thickness areas bolting to be need to be corrosion expensive requirements resistant material (red) (pink)
PATENTED DESIGN Our patented design separates the two requirements of ASME B16.34 Core components (Designed to meet minimum wall thickness requirements) Bolting containment components (Designed to meet minimum bolting requirements)
PATENTED DESIGN CORE COMPONENTS (MADE TO ORDER) BOLTING CONTAINMENT (STOCK PARTS) ALWAYS WC6 (F11) SUITABLE MATERIAL FOR PROCESS MORE EXPENSIVE MATERIAL PAINTED TO RESIST EXTERNAL ENVIRONMENT/GALVANIC CORROSION INEXPENSIVE TO MANUFACTURE
WHAT IS THE ADVANTAGE? Common body/bonnet plate for Class 150, 300 and 600 CLASS 150/ 300 CLASS 600 6pcs, 3/8 through holes (NPS 2 Valve) 4pcs, 5/8 through holes (NPS 2 Valve)
WHAT IS THE ADVANTAGE? Horseshoe plates are the same for Horseshoe Plates have both single and dual packing dual bolting patterns configurations 3/8 through holes (red) 5/8 through holes (blue)
WHAT IS THE ADVANTAGE? Common internals for Class 150, 300 and 600 BASED SAME ON CLASS OUR 600 SHAFT M-CLASS DIAMETER LINE
WHAT IS THE ADVANTAGE? Only four components are manufactured for each application BODY FLANGES BONNET (Single/Dual Packing Bonnet) MOSTLY LATHE WORK MINIMAL MILLING WORK MOSTLY LATHE WORK MINIMAL MILLING WORK LATHE WORK ONLY

BORONIZING
BORONIZING Thermo-chemical surface hardening process Boron atoms are diffused into the surface Results in a case layer that is extremely hard, corrosion resistant, and capable of handling high temperature shocks Inconel 718, 200x magnification.0017 solid layer,.0035 partial layer
BORONIZING STARTS WITH THE BASE MATERIAL We use Inconel 718 because it is: Designed for high temperature applications Extremely hard Very corrosion resistant Has a high nickel content to prevent stress corrosion cracking
then it s all about the preparation of parts There are 6 steps before the trim sets are sent to be borided: 1. Rough machining 2. Stress relieving 3. Finish machining 4. Grinding 5. Four levels of lapping 6. Vacuum testing
last it s about the finishing 1) Cleaned to eliminate any residue 2) Boronized using our proprietary boronizing process 3) Finished lapped 4) Vacuum tested
