Double-Offset Butterfly Valves are self-closing due to dynamic torque with the torque peak occurring at about 75 degrees open. Double-offset butterfly valves have reduced breakout torque as well as reduced dynamic torque.

Double paddle mixer is twin shaft with adjustable pitch of the paddle, which enables variation of capacities and degree of mixing. It is ideal for mixing lumpy materials like filter cakes and materials with high moisture with dry material to make the mixture free flowing.
