Application scope: Double disc swing clamp check valves are suitable for nominal pressures of PN10 to PN420 and Class150 to Class2500; Nominal diameter DN15~DN1200, NPS1/2~48; Used on various pipelines with working temperatures ranging from -196 ℃ to 540 ℃ to prevent medium backflow. By selecting different materials, the clamp type check valve can 1
A check valve with a high-pressure check valve disc sliding along the vertical centerline of the valve body. Internal threaded check valves can only be installed on horizontal pipelines. On high-pressure small diameter check valves, a ball can be used as the disc. The valve body shape of a butterfly check valve is the same as that of a globe valve 1
High pressure butt welded ball valves have strong adaptability to pressure and temperature changes due to the valve seat being composed of carbon fiber reinforced Teflon sealing rings and disc springs, and will not produce any leakage within the marked pressure and temperature range. The machining process of the sphere is tracked and detected by ad1
Low temperature shut-off valve refers to a valve in which the closing element (valve disc) moves along the centerline of the valve seat. According to the movement of the valve disc, the change in the valve seat opening is directly proportional to the valve disc stroke. Due to the relatively short opening or closing stroke of the valve stem and the 1
Double directional butterfly valve, double directional pressure butterfly valve, double directional pressure metal hard seal butterfly valve. The use of an inclined elliptical butterfly plate radial dynamic balance sealing system reliably achieves zero leakage in butterfly valve sealing, and has been widely used by users both domestically and inter1
Pneumatic diaphragm valve, also known as diaphragm globe valve, refers to a compression device that is equipped with a flexible diaphragm or a combination diaphragm in the valve body and valve cover, and its closed part is connected to the diaphragm. The valve seat can be a weir shaped or a straight channel wall. The flexible membrane or composite 1
The slow opening and slow closing multifunctional check valve produced by our company is designed and manufactured based on imported products and advanced products of the same type in China. Its main purpose is to be installed on the outlet pipes of water supply systems in high-rise buildings and other water supply systems to prevent medium backflo1
There are three types of valve cover designs for forged steel gate valves. The * type is a bolt type valve cover. Valves designed according to this design form have valve bodies and valve covers connected by bolts and nuts, and wound gaskets (made of 316 flexible graphite) sealed. When customers have special requirements, metal ring connections can1
