Instrument needle valve It is a special type of valve, mainly used for flow regulation and control in instruments and measurement systems. It is usually composed of a slender needle shaped valve core and a valve seat, and the medium flow is controlled by adjusting the position of the valve core.

Main features of instrument needle valve include:

Accurate adjustment: Since the valve core is a slender needle shape, accurate flow adjustment can be achieved by fine-tuning the position of the valve core, which is suitable for occasions with high flow requirements.

Rapid response: the needle valve of the instrument has a simple structure and a light valve core, so it can quickly respond to the change of flow and realize rapid adjustment and control.

High sealing performance: the contact area between the valve core and the valve seat is small, which can achieve high sealing performance and reduce the possibility of leakage.

Small flow control: The instrument needle valve is suitable for small flow control and can accurately adjust small flow changes.

Applicable to low pressure difference: because the valve core is slender needle shaped, and its area through the aperture is small, it is suitable for flow control under low pressure difference.

Instrument needle valves are widely used in laboratories, instruments, measurement systems and other fields. Common applications include flow regulation and control of flowmeter, pressure gauge, thermometer and other instruments. When using instrument needle valves, attention should be paid to the selection of appropriate materials and specifications to ensure that they can adapt to the nature of the medium and working conditions, and correct installation and operation should be carried out according to the instructions.
