Main usages

J6/41H/Y series water sealing globe valve exquisite selection is in line with domestic and international relevant standards, the sealing part matching is advanced and reasonable, improved sealing performance, and the service life is long. The stuffing box is designed as water sealing structure, access to 0.6 ~ 1.6Ma water packing, friction is small, and the sealing is good, enabling the system isolated from the atmosphere, to ensure a good air tightness. It is a green product. After tempering and surface nitriding treatment, the stem has good anti-corrosion, anti-scratch and abrasive resistance. The inverted sealing uses stainless steel Screw connection sealing or body welding austenitic stainless steel, sealed and reliable. Packing replacement can be processed in non-stop circumstances, it is convenient and not affect system operation. Products are designed and manufactured according to national standards GB/T12235, with novel structure, beautiful shape. Connect end is flange and welding, can match according to different requirements of customers, with compact structure, flexible operation, convenient maintenance. The valve is suitable for the system pipes of fire power plant backwater condensate systems and petroleum, chemical and air separation that nominal pressure is PN2.5 ~ 4.0MPa, and working temperature is 0 ~ 450 °C, works as cutting off or connecting the pipe media. Applicable medium: water, oil, steam and non-corrosive gases
