CST-K Series

Composite body fluoropolymer lined butterfly valves for critical service and high temperatures

 

The CST-K Series fluoropolymer lined butterfly valves feature a composite thermoset plastic body and TFM seat. These valves are designed for zero leakage in the toughest of corrosive applications up to 130°C (265°F) at 150 psi. TFM is a superior grade of PTFE. The properties of the high density TFM liner provide superior performance vs. conventional PTFE lined valves. These include lower cold flow (deformation) and less permeation for longer life with aggressive chemicals. The one-piece shaft/disc is overmoulded with PFA which is a high density material also. The vinyl ester body reinforced with carbon and glass fibres is essentially indestructible and has outstanding external corrosion resistance.

2" to 12" Wafer or Lug ANSI Class 150 lb drill pattern; VE-CF Vinyl Ester, Carbon Filled; PFA Covered 316 SS disc; TFM Seat and Shaft Seal; FDA Grade FKM (Viton®) or Silicone, EPDM Seat Back-ups; -40°C to 130°C (-40°F to 265°F)
