Product overview
Clamp connection lifting check valve, also known as clamp check valve, is mainly composed of valve body, disc, spring, etc., can be installed horizontally or vertically in a variety of pipeline systems to prevent medium backflow, with short structure, small size, light weight and other advantages. The valve disc closes quickly, the water hammer pressure is small, the flow channel is smooth, the fluid resistance is small, the action is sensitive, and the sealing performance is good. It is mainly suitable for clean media, and should not be used in pipelines containing solid particles and medium with large viscosity. It can be installed at the outlet of the water pump, which can avoid water hammer, water hammer sound and destructive impact, achieve the purpose of preventing reverse flow and protecting equipment, and have a good energy-saving effect.
Product features
1. The product structure is short in length, small in size and light in weight.
2. The sealing disc can be selected as soft seal or hard sealing material according to different working conditions, and the sealing performance is good.
3. Horizontal or vertical pipelines can be used and easy to install.
4. The valve disc closes quickly and the water hammer pressure is small.
5. The material of the parts and the form and size of the valve end face can be reasonably selected according to the actual working conditions or user requirements to meet various engineering needs.
