Butterfly valves of PA 600 series
Butterfly valves series PA600 are valves with a symmetrical disk arrangement and wafer-type connection (with smooth or threaded lugs).
Valves of this series are designed and manufactured taking into account the European requirements for design, construction and quality. A distinctive feature of the butterfly valves series PA600 is a soft seat with no hard ring-base, without pin connection between disc and stem. Valve stem fastening in the body excludes its "pulling out" during operation. Valves may be installed in any spatial position.
The design of valves series PA600 is ergonomic, reliable and compact. The design and technological solutions allow repair and maintenance of the valve, replacement of the seat and disk without special equipment and fittings by the technical staff of operating organizations.
Valves series PA600 series are equipped with various versions of electric, pneumatic actuators, sets of mating flanges and fasteners, as required by the customer.
