NBR Seat Butterfly Valve

NBR seat butterfly valve is a kind of using nitrile butadiene rubber as sealing material. It combines the structural advantages of the middle line butterfly valve and the oil resistance, chemical resistance, wear resistance and other properties of NBR materials, and is widely used in petrochemical, food processing, water treatment and other fields.

Why choose NBR seat butterfly valve?

The centerline butterfly valve with NBR seat is selected mainly because of its oil and chemical resistance, which is very suitable for handling oil, solvents and other media. The center line design makes it simple in structure, easy in operation and reliable in sealing. NBR material has the advantages of abrasion resistance, low temperature resistance, chemical corrosion resistance, while the cost is low, suitable for medium and low pressure fluid systems, widely used in petroleum, chemical, food and other industries, providing cost-effective fluid control solutions.

When using NBR seat butterfly valve, the following points should be noted:

Temperature limit: Ensure that the operating temperature is between -30°C and +100°C.

Medium compatibility: Avoid contact with incompatible media such as strong acid and alkali.

Pressure limit: Suitable for medium and low pressure systems, the maximum pressure is usually not more than 1.6MPa.

Avoid excessive friction: Check valves regularly to prevent wear and tear.

Avoid sun exposure: Reduce long-term exposure to UV rays.

Correct installation: Ensure that the valve is installed in the correct direction and maintains a good seal.
