This multi-turn valve derives its name from the needle-shaped closing element. The design resembles that of the globe valve. Typically available in smaller sizes, they are often used on secondary systems for delicate control and shut off e.g with analysers. (0916051)
A two-way valve that may be opened or closed to block the flow of fluid in a passage.
Normally manually operated, but may be automated, especially for larger sizes.
Normally designed so that the flow of fluid must make a non-straight turn inside the valve body, which results in a desired loss of pressure across the valve when open which is greater than the loss across a gate valve. (0615)
