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.
Double planetary mixers consist of two regularly shaped stirrer blades revolving around the tank on a central axis. It is also known as kneader and dough mixers, are ideal equipment for preparing high quality plastisols of high viscosity. The stirrer blades cover every point within mix can. The mixing is very uniform. The mixers are used for highly viscous fluids and pastes.
