Steel Valves

Offered in several configurations and sizes, the MTD HiSeal™ valve line delivers industry-leading quality and safety. These valves are assembled using a patented process that allows for consistent pressure to be applied to each side of the ball, leading to consistently lower operation torque and lower defect rates. In addition, integrated anti-static devices, fire safety devices and other safety and operation options are available.
