that can loosen and corrode
• Subject to size and damage, the seat can be repaired in the field and in certain cases
repaired from outside the valve without disassembly from the main line
• All iron Parts are fusion boned epoxy coated for corrosion resistance and long life
• Lifting lugs and foot mounting points are integral to the body for easy transportation
• Fully rated bi-directional design
• Top plates are in compliance to ISO5211 for mounting actuators
• Disc connection to shaft is by blind bolting eliminating potential leak paths
• Body and Disc consturction is ductile iron for higher stength and ligher weight
• All valves have raised face flanges
• Optional 316 stainless steel disc edge coating using HVOF profess
• All flange holes are drilled through
