Mach 1

Mach 1

The Mach 1 is a robust, non-lubricated (sleeved) quarter-turn plug valve, specifically designed for ease of maintenance and long-term durability. It is capable of in-line service and repair, allowing operators to perform maintenance and adjustments without removing the valve from the pipeline. This design reduces downtime and maintenance costs, making it ideal for high-cycle applications and industries where reliability and efficiency are critical.
