Imported pneumatic high-performance butterfly valve Imported high-performance butterfly valve Robert brand

Imported pneumatic high-performance butterfly valve (Germany Robert brand)
Product Overview
Germany's Robert imported pneumatic high-performance butterfly valve adopts the latest three-eccentric design principle. The outside of the valve seat is a movable insert and a flange. The tighter the clamp and the greater the pressure, the better the sealing performance. Replacing the valve seat is convenient and simple. You only need to remove the insert to take out the valve seat without disassembling the valve plate and valve shaft. It has the characteristics of good sealing, smooth flow path of the valve body, large flow capacity, low friction between the butterfly plate and the valve seat, long life, wide applicable temperature range, and easy maintenance. The valve actuator adopts gear and rack piston structure, with stable output and reliable action. Mainly suitable for gas transportation and process media with high requirements on valve life. The normal service life can reach one million times
Product Features
Metal seals can be applied to media with slight particles and slurry
br/> , Applicable temperature can reach ℃, the highest pressure
, There is almost no friction when sealing, ensuring smaller torque and better sealing
, Flange to clamp hole connection is suitable for a variety of standards.
