Torque for butterfly valves cannot be determined using a generic method. You must request the conversion table from the manufacturer.
how to calculate gate valve torgue. What is the torgue required for 1100NB gate vave used for 3kg/cm2 steam line
because this valve has a centric line through it, and control by a stem going through the disc and drive it open just like a wing of butterfly, that is why it is called butterfly valve
The first carburetor butterfly valve was invented by Carl Benz in 1893.
A butterfly valve is from a family of valves called quarter turn valves. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is open, the disc is rotated a quarter turn so that it allows unrestricted passage. The position of the disc is effected from outside the valve. gas butterfly valve is one kind of butterfly valve, the main feature is that all the functions are supported by gas just as the Electric Butterfly Valve which supported by electric.

The vehicle manufacturer will quote a torque figure for the EGR valve but in practice most mechanics no not torque them.
how to calculate hydraulic motor torque
a butterfly valve.
valve cover torque 98 nissan2.4
The torque converter solenoid is inside the transmission on the valve body.The torque converter solenoid is inside the transmission on the valve body.
89inch pounds is the torque rating for the valve cover bolts
The only butterfly valve I am aware of is in the carbuerator and contols air flow. Few cans still use this item.
