Recommendations

• Polyester coated ribbed wafer or lug bodies to provided extended necks for insulation and be able to install between ANSI 125/150 flanges. Lug design in sizes 2-12” to be fully rated for dead end service without any modification.
• Streamlined disc design with no pins or screws in the flow path and designed for high Cv and lower pressure drop.
• Upper and lower shaft design to utilize triple shaft seals as standard.
• Blow out proof design utilizing a machined Double D drive for a positive disc/shaft connection.
• Pressure responsive 360° sealing design will use constant pressure between machined radius on disc and flatted area of the seat.
• Valve to be Flow Line Series 70 wafer or Flow Line Series 71 lug design.
