Lug pneumatic butterfly valve TLD671X

Posted by Bundor valve

Lug type butterfly valve drive mode can choose manual, worm gear, pneumatic, electric, can choose flange, the clamp connection mode, can choose single eccentric structure forms, line type, double eccentric, triple eccentric, sealing structure can choose soft seal and hard seal, pressure range PN0.1-10 mpa, nominal diameter for DN40-2000 mm, the material can choose cast steel, stainless steel.Because of the wide range of use of the valve, the same valve in different situations and working conditions have different collocation.

The butterfly plate of the clamping lug butterfly valve is installed in the diameter direction of the pipeline.In the cylindrical channel of the butterfly valve body, the disc-shaped disc rotates around the axis with a rotation Angle of 0°-90°. When it is rotated to 90°, the valve is in full open state.


Double-headed butterfly valve is used to connect the valve between two pipe flanges. It is simple in structure, small in size and light in weight, and only consists of a few parts.And only need to rotate 90° can be fast opening and closing, easy to operate, and the valve has good fluid control characteristics.Butterfly valve in fully open position, butterfly plate thickness is the only resistance when the medium flows through the valve body, so through the valve produced by the pressure drop is very small, so it has a good flow control characteristics.The butterfly valve has two seal types: bullet seal and metal seal.Resilient seal valve, seal ring can be embedded in the body or attached to the disc periphery.

Applicable Scope:

Butterfly valve is not only widely used in petroleum, gas, chemical industry, water treatment and other general industries, but also used in the cooling water system of thermal power stations.

Used for gas pipeline in sulfuric acid industry: the inlet and outlet of blower in front of furnace, the inlet and outlet of relay blower, electric defogging series and connecting valve, the inlet and outlet of S02 main blower, converter adjustment, preheater inlet and outlet adjustment and cut-off gas.

Used in sulfur burning, conversion and dry suction section of sulfur acid making system, it is the preferred brand of valve used in sulfur acid making device. It is considered by the majority of users as: good sealing performance, light operation, anti-corrosion, high temperature resistance, easy to operate, flexible, safe and reliable butterfly valve, which has been widely used.

Lug butterfly valve is also widely used in the chemical industry, petrochemical, smelting, medicine, food and other industries SO2, steam, air, gas, ammonia, CO2 gas, oil, water, brine, lye, sea water, nitric acid, hydrochloric acid, sulfuric acid, phosphoric acid and other medium pipeline as a regulation and closure device.
