AYVAZ OS&Y Rising Stem Threaded Valve 8″
Clear visual indication and high pressure resistance for dependable flow control.
The AYVAZ OS&Y Rising Stem Threaded Valve is engineered for safe flow control with clear visual position indication. In addition, its outside screw and yoke design places the stem externally, so operators can instantly verify whether the valve is open or closed. Moreover, the rising stem mechanism moves upward during operation, adding a second layer of visual confirmation.
The CR-Ni coated bronze stem raises resistance to corrosive and abrasive fluids, extending service life in demanding lines. Furthermore, the valve operates at a maximum working class of 300 PSI and tolerates temperatures up to 80°C. Therefore, it suits high pressure systems that require stable, repeatable shutoff.
