Description

ChemValve Fluoropolymer Lined Butterfly Valves

ChemValve Type CST-K 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.

✓ Light Weight
A 72” Damper Butterfly Valve weighs 950 lbs.
✓ Custom Designed
Engineered for specific service condition
✓ High Strength
Made of high elongation vinyl ester resin for high resistance to impact and thermal shock.
✓ Abrasion Resistant
Valves can be designed to provide high abrasion resistance outperforming all other materials of construction
