Pneumatic high pressure hard seal butterfly valve, high pressure hard seal butterfly valve, hard seal butterfly valve

Pneumatic high pressure hard seal butterfly valve, flange connection, pressure PN6.4-10.0MPa, material: SS304, SS316, SS316L, 2507,2205,1.4529, 904L, 254SMo stainless steel. Model D643H, D643Y, D643W, D643F, size DN50-DN800.

Pneumatic high pressure hard seal butterfly valve used in PN64, PN100 pressure conditions, the use of large pneumatic, double cylinder double piston fork type pneumatic, two split cylinder, output torque, flexible and stable action. The inner wall of the cylinder block and the piston shaft are plated with hard chromium, which has good wear resistance. All sliding parts are equipped with oil-free lubricating shaft and guide ring, which reduces the friction coefficient and prolongs the service life.

Dynamic high pressure hard seal butterfly valve is widely used in many industrial fields due to its excellent performance, including:

Petrochemical industry: used for the transportation and cutting of crude oil, natural gas and chemical media, such as the pipeline system of refineries and chemical plants.

Power industry: suitable for boiler steam system, high temperature flue gas treatment, desulfurization and denitrification and other conditions.

Metallurgical industry: used in blast furnace gas, hot blast stove, high temperature dust and other harsh environment

Pharmaceutical and food industry: in aseptic, clean, high requirements of the occasion, the use of stainless steel hard seal butterfly valve, to ensure no pollution.

Water treatment and environmental protection industry: used in sewage treatment, seawater desalination, flue gas desulfurization and other systems, corrosion resistance, wear resistance.

Papermaking and building materials industry: suitable for pulp, lime paste, cement and other granular media control
