Electric Motorized Actuated Shut off and Regulating Needle Valves

Needle valves give you the ability to manage that flow as closely as you need to due to the specialized shape of their plunger. Gradual adjustments of the stem and plunger enable smooth flow control. It can also handle high pressure.

how needle valve works

How do they work.

When you turn the handle of a needle valve, it raises and lowers a tapered plunger to open or seal the valve. The plunger moves up and down on threads inside the shaft of the valve, and there’s a locking nut to prevent it from unscrewing all the way out.

Because the plunger moves up and down on threads, you can very accurately control where the tapered end of the plunger sits in relation to the valve seat. This allows you to control flow very precisely between maximum and zero.

In Motorized Version, it is precisely moved with the help of motors and position feedback controls to achieve the desired output parameters.

Frequently Asked Questions

A needle valve is a type of valve used to control the flow of a fluid, typically in a system where precise flow control is required. It consists of a slender, tapered needle-like plunger that fits into a conical seat. The needle can be rotated, allowing for fine adjustments to the opening through which the fluid passes.

The primary function of a needle valve is to regulate the flow of fluids with high precision. By turning the handle or wheel attached to the needle, the user can control the size of the opening and, consequently, the rate of fluid flow. This fine control makes needle valves suitable for applications where even small adjustments in flow rate are critical.

There are three general needle valve designs: straight, angle, and multiport. In addition, needle valves can operate manually, electrically, pneumatically, or hydraulically

The ‘Needle Valve’ controls flow in both directions, whereas the ‘Flow Control’ valve controls flow in one direction and provides full-flow in the reverse direction. Both are typically used in flow meter applications, primarily when a consistent, calibrated, low flow rate must be maintained.
