What kind of throttle valve is a needle?
Needle Type Throttle Valve: The needle type of throttle valve regulates the fluid flow rate by adjusting the size of throttle area through the axial movement of needle throttle poppet.
How does the size of a throttle valve affect fluid flow?
The needle type of throttle valve regulates the fluid flow rate by adjusting the size of throttle area through the axial movement of needle throttle poppet. Simple structure, but longer throttle gap with small hydraulic force radius, therefore, the needle throttle valve is easily be blocked and influenced by hydraulic oil temperature.
What do you need to know about needle valves?
A needle valve is a manual valve that used where continuous throttling of flow is required for regulation. Needle valves are similar to the globe valve in design with the biggest difference is the sharp needle like a disk. Needle valves are designed to give very accurate control of flow in small diameter piping systems.
Is there a one way throttle check valve?
The throttle valve is often installed with a one way check valve to become one way throttle check valve, there are threaded type and modular type (Including sandwich type) as per the way of connection.

What are the basics of a throttling valve?
THE BASICS OF THROTTLING VALVES THROTTLING VALVES Valves that are utilized as fluid control devices are typically “throttling valves”. Such valves experience internal velocity and internal pressure gradients (both positive and negative) that conclude with a permanent pressure loss (∆P) from the inlet pipe-to-outlet pipe connections.
Is the seat the same as a needle valve?
A seat can be a soft, metal, or composite, same as a globe valve. Normally needle valves are used in smaller sizes and are provided with either screwed or socket weld end. All the aspects of needle valve are the same as a global valve except its size and pointed needle-like disk. You can refer to a globe valve for more detail.
Why are some throttlers unsuitable for certain throttlers?
Valve design is one of the major reasons why some valves are unsuitable throttlers. Globe valves are one of the most popular kinds of valves. The globe valve is primarily used as a throttling valve. This belongs to the linear motion valve family. The globe disk moves up or down in relation to the stationary ring seat.
