'<br>A Knife Valve (also called a Flathead Valve or a Rotary Valve) is simply a rotating mechanical device that opens a liquid tube or pipe when an applied force over a marked boundary causes the valve to rotate. This type of valve has no pressure sensitive interstices, therefore only basic restrictions such as pipe bends, stem damage and stem line flapping will affect the operation. Even so, this type of valve is very reliable and widely used for numerous applications. Some examples include gas valves, water valves, firebox valves, water and steam distillation valves, gas valve annulers and many others.<br><br><br>These types of valves are available in different styles depending on their application and thus selection usually depends on the exact application where it is required. For instance, the gas valve can be classified according to its shape, design and the actuator used. The best way to choose a knife valve is based on its use; this is because each variety is designed to handle a specific type of work load. Thus you must select the one that best meets your requirements.<br><br><br>The flathead type is characterized by its fully adjustable stem. Its free end includes a pair of serrated teeth that form an L-shape.

These types of valve are widely used in plumbing applications like household faucets and lavatory valves. At the other end, the concave-conical stem consists of straight, evenly spaced teeth. The flathead variety is also available in a few different sizes; these are typically in the range of twenty-five to thirty-two millimeters in diameter. The most popular brand among plumbing hardware shops is the red valve company's series of valve series; it is also available in different sizes, depending on the application.<br><br><br>Cam locks differ from other knife valve types by having an additional lock that prevents the flow of hydraulic fluid. Its key is positioned in a groove on the cam, which when activated by the wrenching action of the hands, locks the flow of fluid. Cam locks are commonly found on shower valves and hand rail sections.<br><br><br>The screw jack knife valve, sometimes called a jackhammer knife valve, is typically low pressure sludge free style valve that provides for easy control of water flow. This type usually features a stainless steel sleeve and free end caps with diamond studs or other decorative accents. The valve is commonly found in applications requiring high pressure shutoff and low pressure bleeding. Its free end is designed with a sharp hook and loop feature for securing the stem within a clamp or channel.<br><br><br>These are only some of the types of knife gate valves available on the market today. Many of them have varying degrees of water flow control and operation, which is why they can be used in so many different applications. However, they are most commonly found in applications requiring high pressure bleeding or rapid pressure reduction. It is important to ensure that the correct valve style is chosen for the application in question. A qualified professional can usually assist with selecting the right valve for the application.<br>'
