A HEAVY duty range of butterfly valves designed for underwater marine exhaust applications has been released by Australian Pump Industries .
Designed for both military and commercial vessels the valves are manufactured by the Rathman Group in Germany.
Manufactured from high grade stainless steel and special saltwater and corrosion resistant alloys, the valves are designed to provide increased fuel efficiency as well as fulfilling some specialised military requirements.
The valves incorporate a water jacket for saltwater cooling and are fitted with either manual or micro switch driven pneumatic actuators for infinitely variable aperture control.
"Rathman valves are used in patrol boats and coast guard vessels around the world as well as high speed ferries and tugs," an Aussie Pump spokesman said.
Valves can be customised to suit specific application.
