Masoneilan Conventional Butterfly Control Valves

The MiniTork® II heavy-duty automated throttling butterfly valve achieves outstanding performance with a series of exclusive design merits:
Minimal dynamic torque: Custom concave disc construction slashes operational torque compared to generic butterfly valves.
Full bidirectional flow service: The disc’s reversed concave profile generates no flow restriction, maintaining low torque in either flow direction.
Stable operation free of deflection and play: Splined clamped assembly, outboard ball bearings and heavy-duty rigid brackets secure structural integrity for accurate positioning.
Direct-coupled positioners: Stem-mounted position feedback eliminates transmission slack and enhances positioning precision.
Triple bearing setup: Offers stable long-term support and precise guiding for the valve stem.
Prominent position indicator: Enables fast visual check of the disc’s opening position.
Integral cast extended bonnet: Suits process media with wide temperature variations.
Sealed spring-diaphragm actuator: Fully encased moving parts improve corrosion resistance against harsh ambient conditions.
