Installation of indoor butterfly valves Precautions: Indoor water supply system Valves for regulating and controlling piping, all-plastic valves. Consequences Plastic torsional, anti-vibration, anti-shear performance is far better than copper, steel and other materials, with all plastic valves as the control valve, the valve needs to often open and close, the valve stem, the valve was damaged. Preventive measures Indoor water supply system Valve used to regulate and control the pipeline should be made of copper, stainless steel and other valves, the valve body can also be used as plastic, valve stem and spool is a copper valve. Water pump on the butterfly valve for the control valve. Consequences of the valve to occupy a larger proportion of the cross-section of the flow channel, so the larger flow resistance, and easy to hang debris, blocking the pipeline; pump during operation, resulting in vibration, some butterfly valve in the vibration state of autistic tendency. Preventive measures Pump suction pipe should not be used as a butterfly valve, but should use less resistance gate valve as a control valve.
