Automation Product Solutions

Introduce world-advanced technology for valve design and manufacture, continuously adopt new materials, new processes, and new technologies to improve the accuracy and quality of product

components and ensure well performance of the product, making N-J VALVE products more competitive and meeting the requirements of various working conditions.The company is constantly researching the formula and processing technology of sealing materials, and able to provide pure PTFE and reinforced polytetrafluoroethylene sealing materials. According to user requirements, various polymer sealing materials imported from the United States are also provided. These materials are suitable for special purposes such as higher temperature, pressure difference and radiation resistance.

Ball Valves - Unique and Flexible Lip Seal for Valve Seat

The first contact part between the ball and the sealing ring is made into a cantilever lip, so as to create a buffer between the valve body and the sealing ring, which automatically compensates for the leakage caused by the wear of the valve seat, the change of temperature and pressure, and the plastic deformation, and improves the sealing performance and lifecycle.

Butterfly Valves - Lip Seal and Double Eccentric Design

Lip seal - The sealing seat of the PTFE lip seal flexes when it is closed, and it fits tightly with the outer edge of the butterfly plate in the spherical sector, ensuring a reliable seal. The valve body and inserts fasten the sealing seat in place and isolate their sealing surface from the medium to prevent corrosion.
Double eccentric design - The eccentric butterfly plate and the offset shaft ensure that when the valve is opened, the sealing surface of the butterfly plate quickly detaches from the sealing surface of the valve seat, so that there's only short contact, which prolongs the lifecycle of the valve and also maintains the tightness of the entire periphery of the butterfly plate.

Pipeline Ball Valves – Ideal for Oil and Gas Transmission

Pipeline Ball Valves- A dedicated ball valve designed according to the special technical requirements of long-distance pipelines. It adopts a fixed ball, a floating seat design, a three-section forged steel valve body, and a bolt connection structure, which is convenient for online maintenance. It is an ideal valve for medium control of oil (crude oil, refined oil), natural gas and other transportation pipelines.
The product can be used in harsh natural environments. It can withstand the effects of combined loads such as earthquakes, ground loads, pipeline stresses, etc. in the wild environment.

From Market Development, Order Placement to Product Delivery

The company adopts multiple information technology platforms, including ERP, CRM, MES, CAD/CAM, OA, etc.

Performance Characteristics of Products

We constantly improve the sealing performance of the valve, when there exists a large difference range of pressure and temperature. Maintaining low operating torque and long lifecycle to reduce the leakage of valve stem packing is also our tireless goal.

Floating ball valves

The full channel and low flow resistance characteristics of the ball valve have been widely used in oil and gas pipelines, and are quickly accepted by the nuclear industry, aerospace industry and other high-tech fields, used to transport dangerous media and ultra-low temperature liquids. After that, the new areas of high-parameter ball valves were constantly expanded for: large diameter, high pressure, low temperature, ultra-low temperature, high temperature, high vacuum and solid particle transportation.

High Performance Eccentric Butterfly Valves

Design for single valve seat, flexible and reliable
Design for eccentric butterfly plate and the offset shaft
Refractory structure
Reliable fixing of the shaft
Convenient maintenance of valve seat
Two-way bubble-free leak test
long lifecycle and less for maintenance

According to the sealing principle and sealing technology of the ball valve, there are wafer and earring type for the innovative single-seat high-performance butterfly valve.
The design of eccentric butterfly plate and the offset shaft ensures that when the valve is opened, the sealing surface of the butterfly plate quickly detaches from the sealing surface of the valve seat, so that there's only short contact, which prolongs the lifecycle of the valve.
