DAMPER BUTTERFLY VALVE
FEATURES
Compact structure, light weight
Easy to operate Large flow
High temperature resistance
Good sealing performance
Low failure rate
Wide application range
OVERVIEW
Damper butterfly valves are used in dusty cold or hot air gas pipelines in ventilation and environmental protection projects in the chemical, building materials, power stations, glass and other industries as pipeline control devices for regulating flow or cutting off gas media. This type of valve should generally be installed horizontally in the pipeline.
FEATURES
1. Designed and manufactured with a new structural form of welding the centerline butterfly plate and the short structural steel plate, it has a compact structure, light weight, easy installation, small flow resistance, large flow volume, avoids the influence of high temperature expansion, and is easy to operate.
2. There are no connecting rods, bolts, etc. inside, reliable operation and long service life. It can be installed in multiple positions and is not affected by the flow direction of the medium.
Purpose
The damper butterfly valve is a non-sealed butterfly valve, which is widely used in the production process of building materials, metallurgy, mining, electricity, etc., with a medium temperature of ≤300C and a nominal pressure of 0.1Mpa. It is used to connect, open and close or adjust the medium flow.
PRODUCT DETAILS
The whole is made of high-quality materials, which is harder than ordinary materials, easy to operate and has a long service life.
We use testing equipment to strictly test the product size and take our products seriously.
It can be customized according to customer requirements and we will provide you with the right solution.
Name: Damper valve

INSTALLATION TIPS
1. The installation position, height, and inlet and outlet directions must meet the design requirements. Note that the direction of the medium flow should be consistent with the direction of the arrow marked on the valve body, and the connection should be firm and tight.
2. The appearance of the valve must be inspected before installation, and the nameplate of the valve should comply with the provisions of the current national standard "General Valve Marking" GB 12220. For valves with a working pressure greater than 1.0 MPa and a cut-off function on the main pipe, strength and tightness performance tests should be carried out before installation, and they can only be used after passing the test. During the strength test, the test pressure is 1.5 times the nominal pressure, and the duration is not less than 5 minutes. The valve housing and packing should be leak-free to be qualified. During the tightness test, the test pressure is 1.1 times the nominal pressure; the test duration meets the requirements of GB 50243.
