Rotary Actuators

Motor Butterfly Valve Actuator

The VH Series High Performance Butterfly Valve features a double offset (or, double eccentric) shaft design to minimize seat abrasion and lower torque. This double offset design allows the disc to lift off and “cam” away.

The VH Series High Performance Butterfly Valve features a double offset (or, double eccentric) shaft design to minimize seat abrasion and lower torque. This double offset design allows the disc to lift off and “cam” away from the seat as it rotates open. The VH series valve always rotates clockwise to close (when viewed from above) and counter clockwise to open. The valve body has an Over travel Stop which prevents the disc from over rotating into the wrong quadrant. This stop is not to be used as a disc position stop; if the disc contacts the Over travel Stop, this means it has rotated beyond the seat.

The VH series valve must be installed with the seat in the upstream position (SUS). Note the arrow on the metal tag attached to the valve body.

Every VH series valve has a metal identification tag attached to the valve body. Information includes the Figure Number, the Size and Pressure Class, the Materials of Construction, and the Operating Pressures and Temperatures.
