Product Overview

Axial nozzle check valve is a high-performance valve designed to prevent backflow of media, widely used in petroleum, chemical, electric power, water supply and drainage and natural gas piping systems. The valve is suitable for water, oil, gas and slightly corrosive media, with excellent high temperature resistance, corrosion resistance and pressure resistance. Axial nozzle check valve through the special design of the nozzle structure, the use of the direction of flow of the media to drive the valve opening and closing, to ensure that in the media flow reversal, the valve can be quickly closed to prevent backflow phenomenon occurs, to protect the equipment from impact. Product features include reliable sealing performance, rapid opening and closing, simple structure, small flow resistance. Due to the use of nozzle-type design, the valve can maintain good sealing in high-flow conditions, reducing vibration and noise. The main function of axial nozzle check valve is to prevent the medium in the pipeline from backflow, to protect the stability and safety of the pipeline system, widely used in liquid and gas pipelines, is an important safety valve equipment indispensable to the industrial process.

Product Features

Axial Flow Design: The valve has an axial flow design where the media flow path is aligned with the valve body, thus reducing turbulence and pressure drop. This results in smoother operation, especially in high pressure applications.

Non-Smashing Operation: The valve is equipped with a non-smashing feature that ensures smooth, fast and controlled closure. This avoids the "slamming" effect that occurs in conventional check valves, thus preventing damage to the valve and piping, especially in high-velocity fluid applications.

Precision Nozzles: Nozzle design ensures precise control of fluid flow, improves sealing efficiency and minimizes the potential for valve leakage. Nozzles also help reduce erosion and wear of valve components.

HARD SEAL MATERIAL: Given that the Axial Nozzle Check Valve is used in high-pressure systems, it is constructed with a durable hard seal material that is capable of withstanding extreme pressure and temperature conditions. The hard seal ensures longer service life and reliable performance even under the most demanding conditions.

Compact and robust construction: The valve's compact and robust design makes it ideal for installation in confined spaces, especially in critical piping systems where space is limited and operational reliability is critical.

Product Benefits

High Pressure Resistant: Axial nozzle check valves are ideally suited for use in medium to ultra-high pressure (up to 2500 LB or more) systems, ensuring safety and longevity in demanding applications.

Minimized flow resistance: Thanks to the axial flow design, the valve minimizes energy losses due to flow resistance, which is particularly beneficial for energy-efficient systems.

RELIABLE BACKFLOW PREVENTION: The valve provides reliable backflow prevention without the need for an external power source, providing a fail-safe method of controlling the flow of fluid in the pipeline.

DURABILITY AND RELIABILITY: The components of this valve are made of high-quality materials, such as stainless steel or alloy steel, to ensure that they can withstand extreme operating conditions and maintain optimum performance.

Ease of Maintenance: The valve is designed for easy maintenance and repair, with easily removable parts and simple functions, reducing downtime and operating costs.

Difference between axial flow check valve and ordinary axial flow check valve

1. Fluid flow path design:
Axial Nozzle Check Valves: Axial nozzle check valves have a special nozzle structure inside the valve body. The internal fluid passages are guided by nozzles or fine directional devices to more accurately control fluid flow. This nozzle structure helps to simplify fluid flow, reduce turbulence, and ensure a smoother passage through the valve while improving flow control accuracy.

Ordinary axial flow check valve: In comparison, the structure of ordinary axial flow check valve is relatively simple.

2. Flow control and pressure loss:
Axial Nozzle Check Valve: The nozzle design of the Axial Nozzle Check Valve helps maintain a smoother fluid flow with less turbulence and vibration. This construction reduces pressure loss during flow, improving the flow efficiency and energy utilization of the system.

Ordinary Axial Flow Check Valves: Ordinary axial flow check valves have a simpler construction, which can lead to greater resistance to flow and pressure loss. This can lead to increased energy consumption and reduced system performance.

3. Sealing performance:
Axial Nozzle Check Valves: Axial nozzle check valves provide more precise sealing performance, especially in high-pressure, high-velocity fluid applications. The nozzle design contributes to better sealing control, which enhances leakage prevention. In addition, material selection and nozzle shape can improve sealing in harsh conditions such as high pressure and temperature.

Ordinary Axial Flow Check Valves: Ordinary axial flow check valves rely more on the valve flap and spring assembly for sealing. While they can perform basic flow control functions, they may not perform as well as regular axial flow check valves in applications where sealing accuracy is required at extreme pressures or temperatures.
