Product Description

The needle valve is a type of valve with a small port and a threaded, needle-shaped plunger. It allows precise regulation of flow and is commonly used in flow-metering applications, especially when a constant, calibrated flow rate must be maintained. It is ideal for idle fuel flow in carburetors, steam piping in power plants, and providing shut-off for pressure gauges across various industries.

Key Features & Applications

• Accurate and precise control of flow rate and pressure.
• Provides reliable cutoff functionality.
• Precise adjustment for flow, bearing resistance, and pressure regulation.
• Suitable for pump start, turbine by-pass, flow discharge, and air regulation.
• Compact small size for versatile installation.
