Manual Butterfly Valve is a very common butterfly valve products, widely used in hydraulic engineering, municipal construction water, sewage discharge, fire pipe, is a simple structure, easy to install, easy to operate the valve. Manual butterfly valve in the pipeline to play its role, the need to pay attention to the selection of configuration, installation specifications, and so on. this article introduces you to manual butterfly valve installation requirements.
Manual Butterfly Valve Installation Requirements
1. Manual Butterfly Valve before installation, not optional drop, need to be placed in a cool, dry and ventilated environment, and covered well, to avoid the valve being contaminated with dust and other debris, affecting its later use.

4. Manual butterfly valves require frequent manual operation. So the installation location of manual butterfly valve is also very particular, valve installation location must facilitate the operation of personnel and future maintenance, there is an argument that the best location for manual valve installation is about 1.2 meters operating floor. For valves installed outdoors, cover the valve with some covering to prevent the valve from being affected by bad weather.
5. Installation, manual butterfly valve disc must be in the closed state, so as to avoid disc and pipe flange damage, affect the sealing performance.
