Some parallel disk gate valves used in high pressure systems are made with an integral bonnet vent and bypass line. This valve's main objective is to allow only a certain flow of air through the system so components with a higher or lower pressure rating don't get the wrong amount of pressure. As the disc is offset from the shaft, there is a lot of metal in the flow stream in the wide-open position, and double-offset valves have somewhat less maximum capacity than flat-disc, non-offset valves. The type of unit used to provide pressurized air for pneumatic systems is determined by the system's air pressure requirements. In opposition to expensive imported products, Fujikin developed its first patented product, the Needle Valve. The adjustable part will usually be a tapered-nose rod, that is similar to how a needle looks, which is threaded into the valve body. This gets back to one of our core fundamentals when selecting a proper valve - determine operating pressure and maximum pressure for the intended plumbing system.Hermetic Isolation of the fluid from atmosphere (diaphragm) giving higher flow rates than conventional diaphragm valves. The valves control the throttle in a car. For example, a check valve can prevent a steam boiler from building up too much pressure or a car's radiator from rupturing when the coolant fails: the check valve will divert the high pressure media away from the process and avoid catastrophic failure.

Sebuah butterfly valve, diilustrasikan pada Gambar di bawah ini, adalah gerakan berputar valve yang digunakan untuk berhenti, mengatur, dan mulai aliran fluida. Open the valve at the bottom of the cylinder and press the check valve on the charge set to purge the air (be careful of the liquid refrigerant). The maximum working pressure of Needle valve is 10,000psi and maximum working temperature up to 230°C or 427°C with GP option. That being said, solenoid valves can be controlled remotely and are used in a number of industries. Lift check valves are suitable for installation in horizontal or vertical lines with upward flow. There are 2 available connections for needle valves namely NPT (National Pipe Thread) and BSPP (British Standard Pipe Parallel), and it comes in two variations, which is the Bar Stock Needle Valve design and Bonnet Needle Valve design. The seat ring may be threaded or screwed to the body of the valve. Needle valves offer the most accurate flow control, making them an excellent choice for precise metering of liquids or gases. The signiﬁcant feature of the gate valve is less obstruction to flow, with less turbulence within the valve needle valve and very little pressure drop.
