Fire Fighting System Use Ductile Iron Worm Gear Operated
Product introduction:
Fire fighting valve products are control accessories on industrial and building pipelines. Fire fighting valve is the most important controlled accessory on industrial and building pipelines, normally consisting of valve body, opening and closing mechanism, and valve cover. Simple structure and reliable sealing.
Middle-line soft seal butterfly valve with level operation is the preferred conventional butterfly valve for for fire fighting pipeline use. The utility model has the advantages of simple structure, small flow resistance coefficient, near-straight flow characteristics, and is free of debris, in light weight, convenient to be installed, and small in driving torque. This valve can be used to cut off media and also to regulate the flow of media used. Its actuating device can be upgraded according to user's requirements, such as worm gear operation, electric and pneumatic actuator etc.
