H77X-16Q clamp soft seal check valve

Product Overview:

H77X-16Q clamp soft seal check valveAlso known as double disc swing check valve, it is composed of valve body, valve disc, valve stem, spring and other parts, and adopts a clamp type connection with a compact structure. Due to the short closing stroke of the valve disc and the spring loading, the closing speed is fast, which can reduce water hammer phenomenon. The product has the advantages of small size, light weight, sensitive action, reliable sealing, and easy installation. It can be installed horizontally or vertically and is suitable for various media such as water, steam, oil, nitric acid, acetic acid, and strong oxidizing media. The H44 flange connected swing check valve, which is traditionally used, has disadvantages such as bulky volume, high fluid resistance, high water hammer pressure when the valve is closed, difficult installation and maintenance, and short service life. The valve supply network has developed and produced a series of clamp type check valves to address the problems of traditional flange structure check valves. The H76 clamp double disc swing check valve has a short structural length, small volume, light weight, fast valve disc closure, low water hammer pressure, easy installation, low fluid resistance, sensitive action, good sealing performance, short valve disc stroke, low closing impact force, simple and compact overall structure, long service life, and high reliability.

Structural features:

1. The structural length is short, only 1/4 to 1/8 of that of traditional flange check valves;
2. Small in size and light in weight, its weight is only 1/4 to 1/20 of traditional flange check valves;
3. The valve disc closes quickly and the water hammer pressure is low;
4. Both horizontal and vertical pipelines can be used for easy installation;
5. Smooth flow channels and low fluid resistance;
6. Sensitive movement and good sealing performance;
7. Short valve disc stroke and low impact force when closing the valve;
8. Overall structure, simple and compact, beautiful appearance;
9. Long service life and high reliability.
