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.
Gear pumps use intermeshing gears to pump various types of liquids. Typically, one gear is the driver and the other is free wheeling. The gears have very tight tolerances so that the fluid being pumped cannot pass through them. Common uses for gear pumps include high pressure, metering, and flow control applications.
Industrial hose covers the broad spectrum of fluid transfer lines. Hose is usually flexible, often reinforced, and available in a wide range of material compositions to cover various hydraulic and pneumatic industrial applications.
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.
