Needle valves are small valves used for flow control in liquid or gas services. The fine threading of the stem and the large seat area allow for precise resistance to flow.

Check valves are self - activating safety valves that permit gases and liquids to flow in only one direction, preventing process flow from reversing. They are classified as one - way directional valves. Fluid flow in the desired direction opens the valve, while backflow forces the valve closed. The mechanics of check valve operation are relatively simple.
