Needle valves for accurate flow and pressure regulation

Needle valves are regulating devices that allow precise flow and pressure control, making them highly functional as gauge isolation valves to protect from pressure surges damaging the gauges. They are commonly used in low flow-rate processes that require accurate throttling of pressure or in bulk tank gauging lines, trailers and other similar applications.

Product description

Pressures in appliances using cryogenics are usually sensitive to higher pressures and the needle valves help regulate the pressure to a desired output. Pressure regulation is manually actuated by using the handwheel that require multiple turns for a small regulation of gas and fluid flow/stop.
