Product Introduction

H47X series products is my company's latest research and development of soft sealing double eccentric flange connection micro-resistance slow closing butterfly check valve, mainly used in petroleum, chemical, food, medicine, textile, paper, water supply and drainage, metallurgy and energy system as a one-way valve, used to prevent medium countercurrent and destructive water hammer.

Features

1. Small size, light weight, compact structure and convenient maintenance.

2. The slow closing device has novel design, compact and reasonable structure, stable and reliable performance. And it is located outside the pipeline to avoid polluting the medium.

3. Smooth operation, no vibration, no noise.

4. The double eccentric structure is used, and its structural parameters are determined at the best value, which is conducive to reducing flow resistance and vibration, and reducing the impact of water hammer.

5. To achieve complete sealing, no leakage.

6. Good opening and closing characteristics, valve opening pressure <0.08MPa. Open quickly, the closing valve adopts adjustable, fast and slow two-stage closing mode, slow closing time adjustment range is large, can be applied to different working conditions.

7. Because it does not carry "heavy hammer" and external oil pipe, it avoids accidents such as injury and slow closing failure due to pressure burst of oil pipe. And power saving, energy saving effect is obvious.

 

Products conform to standards

1. The product flange connection size in line with GB/T17241.6-1998 standards.

2. The structure length dimension conforms to the standard specified in the long series dimension of double flange connection butterfly valve in the GBI2221-89 "Flange Connection Metal Valve Structure Length.
