TTV Colossus - PTFE Double Eccentric Wafer Butterfly Valves

Rating

• DN32mm (1 ¼”)- 600mm (24”)
• PN 10, 16, 150#

Design features

• Bi-directional sealing
• Permanent in time zero leakage for air
• Specially suitable for steam or oxygen
• Standard seat: PTFE with 25% of glass fibre, which provides the best balance of mechanical, electrical and chemical properties and a good wear and friction behavior. It resists acids and alkalis, except hydrofluoric acid and strong alkali. If it is required for special applications, there is a wide range of PTFE-based polymers, F-316, graphite and virgin PTFE
• PTFE + metal ring: Fire Safe
• Low operation torque

Wafer:

• One-piece body with four centering lugs which allows installation between flanges at intermediate points in the pipeline.
• Características del PTFE:
• Almost universal chemical inertness
• Complete insolubility in all solvents below 300°C
• Low coefficent of friction
• Excellent dielectric properties
• Excellent thermal stability
• Nontoxic

• Chemical and pretochemical industry
• Pharmaceutical industry
• Petroleum
