1. Product Features

• Rising Stem (OS&Y) Design: The stem thread is located outside the body, preventing contact with the medium. The stem rises as the valve opens, providing a clear visual indication of the valve position .
• Metal-to-Metal Sealing: The seat and wedge sealing surfaces are overlaid or inlaid with Stainless Steel or Copper Alloy, ensuring suitability for high-temperature, high-pressure, and abrasive applications.
• Full Bore Design: Straight-through flow path minimizes fluid resistance and pressure loss, and allows for pigging operations .
• Stem Sealing: Features an adjustable gland packing system. Flexible graphite packing is typically used, allowing for low leakage rates and suitability for high temperatures.
• Applications: Suitable for hot water, steam, thermal oil, sewage, and industrial pipelines .
