Description

Giant – PD Series Butterfly Valves

The Chemline PD Series Giant Butterfly valve has a full elastomeric seat with bubble tight seal. Only the seat (liner) and disc are wetted parts. The disc and seat are spherically designed for long cycle life. The liner is a full seat requiring low bolt torques to seal against piping flanges. PDCPD (Polydicyclopenthadiene) is a polyolefin thermoset plastic. Valve parts are manufactured by a process called reaction injection moulding (RIM). PDCPD has excellent corrosion resistance and temperature ratings, very similar to those of polypropylene. It is durable material offering high impact strength and a fraction of the weight of cast iron.

✓ High Working Pressures
110 PSI for all sizes
✓ ISO Actuator Mounting Dimensions
Top flange and shaft have ISO 5211 standard dimensions for easy actuator mounting
✓ Light Weight
Less then half the weight of cast iron
