Pneumatic Needle Valves
Pneumatic Needle Valve Product Introduction
Definition of Pneumatic Needle Valve
The pneumatic needle valve is driven by compressed air as its power source, achieving millisecond-level rapid opening and closing response. It features high-precision flow control, stable operation, high safety and reliability, as well as multi-scenario versatile functionality.
Suitable for conveying various media including hydraulic oil, water and gas, it serves as an ideal intelligent fluid control component, and a core choice for modern industrial automation system upgrading and transformation.

Structural Composition of Pneumatic Needle Valve
Also known as pneumatically controlled needle valve or pneumatic control globe valve, designed for automated fluid control scenarios
High pressure resistance performance: can withstand ultra-high pressure up to 60000 psi (414 MPa), adapting to extreme high-pressure working conditions
Pressure rating classification: divided into three categories, namely medium pressure, high pressure and ultra-high pressure, to match different system pressure requirements
Control mode: adopts pneumatic control instead of traditional manual control, supporting long-distance remote control, widely used in automated industrial systems
Actuator type: two standard configurations, Normally Closed (NC) with closed state in normal condition, and Normally Open (NO) with open state in normal condition
Overall structure: composed of a special pneumatic controller and a high-precision needle valve body; actuator made of lightweight aluminum alloy to reduce overall weight, needle valve body made of 316 stainless steel for excellent corrosion resistance, high durability and extended service life
Product Features of Pneumatic Needle Valve
Safety and explosion-proof design, suitable for flammable, explosive and other harsh industrial environments
Simple and convenient operation: only a single air pipe is needed to complete pneumatic control, with low operation difficulty
Wide media compatibility: applicable to various media compatible with valve body material, including water, oil, gas and other corrosive or non-corrosive fluids
High-low pressure adaptive drive: uses low-pressure compressed air to drive the pneumatic controller, realizing the closing and opening of the needle valve, to control the on-off and flow of high-pressure conveying media stably
