Product Features

1. Valve body

The internal cavity of the low-noise cage type regulating valve body is composed of two flow channels, the S flow channel and the semi elliptical cross-sectional profile design. The flow channel is unobstructed, reducing flow resistance and effectively reducing turbulence.

2. Valve internals

Valve internals can be made of different materials and surface hardened according to the requirements of the working conditions to increase their corrosion resistance, cavitation resistance, erosion resistance, and improve their service life.

3. Packing system

The packing box has been optimized by placing a dust cover sealing ring inside the packing gland, which can effectively prevent impurities adhering to the outer leakage surface of the valve stem from entering the packing box with the valve stem and causing damage to the valve stem and packing, while also playing an auxiliary sealing role.

4. High precision

The company's independent innovation divides valve internals into three functional areas: guidance, regulation, and sealing. The best solution can be designed according to the different working conditions of each functional area, achieving reliability in various aspects such as action, regulation, and sealing.

5. Corrosion resistance and wear resistance

The main components of the valve are treated with super strong coating, and the surface hardness can reach HV ≥ 2500, which can maintain its stability and service life under harsh working conditions;

6. Easy to maintain

Unique design advantages, standardized production, independent components, easy disassembly and replacement, no need for specialized fixtures, and only simple parts need to be replaced to change the valve type; Components can be flexibly combined with various materials.

Design Features

1. The structure with large stroke and comprehensive guidance improves the stability of the valve core under high pressure drop and high pressure, reduces side load and valve core vibration, and extends the service life of the valve;

2. Standardized and modular design for more reliable performance;

3. The use of piston rings and high-performance sealing rings has improved the leakage level;

4. The stuffing box adopts a maintenance free self sealing design, which is safer and more reliable;

5. Adding a dust cover to the stuffing box system can effectively prevent dust and debris from entering the stuffing box;

6. The valve body is fully compatible with single seat valves and can be replaced with internal components online;

7. Pressure bearing components are designed according to ASME nuclear grade standards, making them safer to use and more suitable for harsh working conditions.

8. The regulating valve adopts a unique high-performance spring sealing ring, which enables it to achieve ANSI B16.104 Grade VI leakage level even under severe working conditions;

9. The valve core adopts a pressure balanced structure;

10. Adopting a small hole type regulating sleeve, it has high-precision proportional and linear flow characteristics, which not only provides good control over gas media, but also reduces noise levels;

11. Adopting single-layer sleeves, double-layer applications, and multi-layer sleeves can meet the needs of users under different working conditions;

12. The spring floating sealing structure developed by the company can solve the vibration generated by the regulating valve during operation, which affects leakage;
