»> Product Overview
The diaphragm valve is fitted with a flexible diaphragm or composite diaphragm in the body and bonnet, and the closure is a compression device connected to the diaphragm. The seat may be a weir or a pipe wall with a straight channel. The advantage of the diaphragm valve is that its control mechanism is separated from the media channel, which not only guarantees the purity of working medium, but also prevents the possibility of medium shock control mechanism working parts in pipeline. In addition, the stem does not need to be individually sealed in any form unless it is used as a safety facility in the control of hazardous media. Diaphragm valve, the work is only in contact with the medium diaphragm and the valve body, both can be used in a variety of different materials, so the valve can be ideal to control a variety of working medium, especially suitable for medium with chemical corrosive or suspended particles. Diaphragm valve working temperature is usually limited by the diaphragm and body lining material used, its working temperature range is about - 50 ~ 175 ℃. The diaphragm valve is simple in structure and consists of only three main components: valve body, diaphragm and valve head assembly. The valve is easy to be disassembled and repaired quickly, and the diaphragm can be replaced on site and within a short time.
