We offer a wide selection of valves in UPVC plastic, this includes double and single union ball valves, wafer butterfly valves, check valves and more all of which are available to order here on our website. All of our UPVC valves have been manufactured by Comer Italy though in some cases due to demand we may supply an Onyx branded product, they've all been manufactured to the BS 4346-1:1969 standard.
Most of these plastic valves are available with both plain solvent weld and female BSPP parallel threaded ends and certain valves are designed to be installed between flanges, these are suitable for PN10, PN16 (BS EN 1092-1) and ANSI-150 (ASME B16.5) pipe flanges. Pressure ratings depend on the size and connection type selected but are usually 10 bar (PN10) or 16 bar (PN16) at ambient with a full operating temperature range of 0 - 60°C.
UPVC is one of the most popular plastics used in pipeline installations due to its robust and lightweight nature as well as excellent resistance to chemicals and abrasion, they also offer good flow characteristics due to their smooth interior bore, they're also tasteless and odourless making them ideal for drinking water and many food installations.
