The HV-02 is a hand-operated rotary valve engineered for high reliability in industrial pneumatic circuits. It allows operators to manually switch between two active flow states or a central neutral position, providing tactile control over cylinder extension and retraction. The valve is constructed with a high-strength aluminum alloy body that is surface-treated to resist corrosion and wear in harsh environments. Its internal mechanism is designed for low operating force, and the ergonomic lever includes a detented position to ensure the valve stays securely in the chosen state during operation.
