Ductile Iron Material Red Color Clamp Connection Gate Valve Fire Protection Valves

Usage:

The valve can be used in the medium temperature is not higher than 80℃ pipeline and equipment for regulating and intercepting the flow

The valve depends on the rotation of the handwheel to turn the stem, drive the gate up or down, so as to achieve the purpose of opening and closing. The effect of sealing can be achieved by compensating the micro deformation produced by the ram under stress.

Valve characteristics

1. Simple shape, light weight, good manufacturing technology, wide range of application, easy to install.
2. Reasonable and compact structure, small volume, close mass parts (gate) using wedge structure, in the work can automatically compensate the abnormal load or temperature caused by the deformation of the valve body, safe and reliable seal.
3. The medium can flow from both sides of the gate valve in any direction to achieve the purpose of connecting or cutting off.
4. Opening and closing is more labor-saving. When opening and closing, the direction of motion of the gate plate is perpendicular to the direction of flow of the medium.
5. Can be used for sewage discharge, gate valve corrosion resistance, prevent the gate plate rust characteristics.

Matters needing attention

1. The valve is kept in a dry warehouse. It is strictly prohibited to store it in the open air.
2. Long-term storage, should be maintained regularly.
3. This product can be installed in any position and any pipeline, the use condition should be consistent with the requirements in the performance specification.
4. Pipe and valve cavity should be cleaned before installation.
5. After installation, the product should not be subjected to large external forces.
6. When the local minimum temperature is lower than 4℃, insulation protection should be done; As the end valve should be used with pipe or jacket heating, to prevent the tube wall temperature below 0℃.
7. It is strictly prohibited to install and use in pipelines that bear vibration or rapid changes in medium temperature.
8. The elastic seat sealing valve should not be installed on the pipeline whose working pressure is greater than the nominal pressure.
9. Elastic interseat valves should not be used on contracted lines unless otherwise recommened or demonstrated by the manufacturer.
10. To prevent damage during operation, it is recommended that the operating torque of DN40 ~ 100be no more than 270N.m and DN125 ~ 300. The value must be less than 400 N.m,DN350to 600 must be less than 500N.m, and ≥DN700 must be less than 700N.m.
