Weir Diaphragm Valve

The GAIRUI Weir Type Diaphragm Valves has self draining function to ensure no residue and make the pipeline cleaner and healthier. The valve body has various materials, such as cast iron, ductile iron, cast steel, forged steel and lining. Lining materials include: Glass, ETFE, PFA, PVDF, Halar rubber, which can be specially processed according to needs. The unique valve cover patent design prevents the diaphragm from being too tight and the pressure is too high, so that the diaphragm is in normal working condition. The seal of the diaphragm can be zero leakage of the valve

The GAIRUI Thread Weir Diaphragm Valves is specially designed to control the general corrosive medium, and can be used for opening and closing and throttling of various pipelines or equipment. The lining valve is suitable for urban construction, chemical industry, metallurgy, petroleum, pharmaceuticals, food, beverages, and environmental protection.

The GAIRUI PTFE Lined Diaphragm Valves is a special type of truncation valve. Its opening and closing is a diaphragm made of soft material. The inner cavity of the valve body is separated from the inner cavity of the valve cover and the driving part. The valve is characterized by the diaphragm separating the inner cavity of the lower body from the inner cavity of the upper valve cover, so that the valve rod and valve disc above the diaphragm are not corroded by the medium, and the packing seal structure is omitted and the medium leakage will not be produced.

The GAIRUI Three Way Diaphragm Valves is used to control non corrosive or general corrosive medium. The inner cavity surface of the valve body is unlined or covered with various kinds of rubber, suitable for different working temperature and fluid pipeline. The variety of lining materials can be applied to all kinds of media and has good corrosion resistance. The valve body and the cover are separated by the middle diaphragm, so that the valve cover and the valve stem part of the diaphragm are not eroded by the medium, and the diaphragm valve is a special stop valve.

The GAIRUI Y Type Diaphragm Valves includes the valve body, the valve stem, the isolation ring, the diaphragm and the diaphragm cavity cover. The diaphragm is provided with a through hole on the top of the diaphragm, which is arranged in contact with the stem and can move along with the stem and extend the hole to the outside. The outer sleeve of the indicating rod is provided with a shaft sleeve, and the shaft sleeve is fixed on the inner wall of the through hole.
