Needle Valves must be easy to shut off, and pressure sensitive to maintain the correct level of flow. The Valves must allow for precise adjustments of flow, and be adjustable to conform to the requirements of a particular system - Needle Valves require many turns of the valve stem to open or close, which means a range of flow, can be allowed for. They are used control flow into delicate gauges, where sudden surges of pressurized fluid can cause damaged, and in situations where flow must be gradually, and precisely brought to a halt. They are also used where a small rate of flow is required. They are not for use in simple shut off applications. The valves should be easy to shut off completely with no more than 'finger tight' pressure. Swagelok Valves guarantee a long service life, and compact design.
In addition to the valve positioners, valve products themselves deserve our attention. There are many categories. Among all those valve types, the check valve is one of the main kinds. It is used to close off piping and to prevent backflow. Backflow occurs when the substance in the pipe flows in the opposite direction when the valve is closed. There are many forms of this type of valves such as ball check valves, stop-check valve, cone check valves, and disk check valve and so on.

The flow is permitted to go when the handle of the faucet is turned counter clockwise. At this time, the water faucet's gate rises. When the water faucet's handle is turned clockwise, the gate is dropped thereby stopping the flow. There are even some types of gate valve that are used in a lot of industries that have electric motors. Signals are sent by human or computer intervention or automatically through a timer.
Added advantages of manual pinch valves include their ability to effectively control the flow of corrosives and abrasives. In addition, there is the lack of contact between any metal part of the valve and the transported material which is a major asset in circumstances where the purity of a product is a high priority. The versatility of the valve is displayed in its ability to handle waste-water, slurries, pulp, powder and pellets, as well as applications in medical and pharmaceutical processes.
These examples of Swagelok Valves give the customer great insight into the care, detail, quality, design and testing that goes into the manufacture of each and every Valve in the Swagelok catalogue. It's easy to see why Swagelok has no hesitation in backing their products with the Swagelok Limited Lifetime Warranty.
