FAQ
What are the primary functions of needle valves?
Needle valves are specialized components used to regulate the flow of high-pressure fluids and gases within pipelines. They derive their name from their plunger design, which resembles that of a sewing needle. This innovative design enables needle valves to achieve precision control over fluid and gas flow. Moreover, they serve the vital role of protecting sensitive gauges from potential damage caused by abrupt pressure changes.
How are hydraulic needle valves different from shut-off valves?
Hydraulic needle valves play a crucial role in controlling flow bidirectionally within pipelines. While they share similarities with shut-off valves, a key distinction lies in their design. Needle valves are characterized by a long plunger, manipulated using a handwheel. The precision control of fluid or gas flow is achieved through the interaction of this plunger with a seat, distinguishing needle valves in their meticulous flow regulation capabilities.
What material are needle valves made of?
Needle valves offer versatility in material choices, with stainless steel and brass being prominent options. Stainless steel needle valves are favored for their durability, longevity and low maintenance requirements. They excel in environments with extreme temperatures.
