Composite Ball & Butterfly Valves
AVT is the only non-metallic valve manufacturer in the world to hold American Bureau of Shipping type approval, TüV approval, Lloyds Register Type Approval, CE Module H certification, ISO9001, API 607 Firesafe, and now USCG 46CFR56.20-15. All AVT’s products are compliant to US Coastguard requirements.
Advanced Valve Technologies specializes in the production of a range of both off-the-shelf and custom-built Valves specifically designed to meet the demands of harsh or extreme environments. Construction is of reinforced composites which give remarkable resistance to corrosion, abrasion and impact, significant weight saving, excellent tensile strength throughout a wide range of operating temperatures and very low thermal conductivity. Valves can be operated manually or remotely.
Advanced Valve Technologies Valves incorporate all the features which users have come to expect from high performance valves combined with the significant advantages available from reinforced composite resin systems tailored to provide optimum characteristics for specific applications. The range used includes Glass Reinforced Epoxy, Vinyl Ester and Novolac Epoxy systems formulated to achieve extended service lives in demanding applications without a requirement for routine maintenance. Continuous research and development ensure that the range maintains its technical leadership at all times.
Remarkable internal corrosion resistance of all Advanced Valve Technologies resin systems eliminates the need for internal protective linings. The key to corrosion resistant performance lies with the careful specification of body, ball, and trim materials.
Lightweight materials provide significant advantages leading to substantial reduction of costs for installation, delivery to site and subsequent maintenance.
Good abrasion and cavitation resistance Reinforced composite systems resist damage caused by abrasion, erosion, and cavitation
Remarkable external corrosion resistance of all Advanced Valve Technologies resin systems eliminates the need for external protection.
Very low thermal conductivity of Advanced Valve Technologies resin systems eliminates the need for external lagging or trace heating even when such treatment of associated pipes is necessary.
Very low galvanic conductivity avoids any risk of galvanic reaction with metal pipes or fittings.
Extended operating temperature range at full rated pressure Resin systems offered permit operation at full rated pressure subject to media through temperature range -40°C to +140°C.
