COVNA HK59-D Cast Iron Pneumatic Operated Butterfly Valve

The HK59-D series has a cast iron body, 316 SS disc, EPDM or PTFE seat and a double acting pneumatic actuator making it suited to a wide range of industrial applications. These wafer butterfly valves will fit all standard flanges and are operated by a high quality double acting (rack and pionion design) anodised aluminium pneumatic actuator. The unique bonded catridge design of the butterfly valve gives it a longer life span, allows vacuum to be run through it and enables the seat to be replaceable if ever the need should arise.
