KHB-YJZQ Series 304 Pneumatic High-Pressure Nitrogen Ball Valve (Internal/External Thread)

Product Overview

The KHB-YJZQ series 304 stainless steel pneumatic high-pressure ball valve is an automatic valve solution integrated with a high-performance pneumatic actuator. It is specifically designed for high-pressure fluid and gas pipelines that require remote control, quick cut-off, or frequent operation. With the corrosion resistance of stainless steel, ultra-high pressure-bearing capacity, and the convenience of pneumatic drive, the product is widely used in key links such as nitrogen purging, gas transmission, and hydraulic control in fields including petrochemical, semiconductor manufacturing, energy and power, and automatic production lines.

Detailed Product Features and Advantages

1. Pneumatic Drive for Intelligent Control

• Fast Response: Single-acting (spring return) or double-acting pneumatic actuator realizes 90-degree quick opening and closing, with a response time up to the second level.
• Remote Automation: Controlled by a solenoid valve, it can be easily connected to central control systems such as PLC and DCS to realize long-distance control and automatic process management.
• Safe and Reliable: In case of sudden air cut-off, the single-acting spring return type can automatically return to the open or closed state to ensure system safety.
• Multiple Accessories: Can be equipped with limit switches, handwheel mechanisms, air source treatment triplets, etc., to meet diverse control needs.

2. High-Pressure Design for Durability

• Reinforced Valve Body: Adopts thickened valve body design and precision forging process, ensuring stable operation under high pressure of 31.5MPa and above without deformation or leakage.
• Rigid Sealing: The ball core and valve seat adopt metal hard sealing or high-performance composite material sealing, which is resistant to high-pressure erosion and has a long service life.

3. Stainless Steel Valve Body for Wide Application

• 304 Stainless Steel: Provides excellent corrosion resistance, suitable for various media such as water, steam, oil products, nitrogen, oxygen, and weakly corrosive chemicals.
• High Cleanliness: The valve flow channel is smooth and easy to clean, meeting the occasions that require medium purity (such as purging gas).

4. Threaded Connection for Flexible Installation

• Internal Thread: After installation, the outer wall of the pipeline is flat with a compact structure.
• External Thread: High connection strength and good vibration resistance.
• Nitrogen Sealing: For gas media, a special sealing design and assembly process are adopted to ensure zero gas leakage.

Detailed Technical Parameters

Application Fields

• Gas Control: Nitrogen purging systems, storage tank protection, gas distribution pipelines, air separation equipment.
• Chemical Processes: Reactor gas inlet control, catalyst protection, reaction processes involving high-pressure gases.
• Semiconductor/Photovoltaic: Transmission and on-off control of high-purity special gases (such as nitrogen).
• Energy and Power: Power station instrument compressed air systems, hydrogen/carbon dioxide systems.
• Automation Equipment: Used as an executive component, integrated into automatic assembly lines and test benches.
