PRODUCT DESCRIPTION<\/h2>\n

1.Rigid gate design
\nThe wedge gate and valve seat are precision-ground hard seals, resistant to particle erosion, the valve body material is tensile and compressive, the force is evenly distributed, and the appearance is beautiful.
\n2.Visualization of rising stem lifting
\nThe exposed structure of the valve stem displays the valve opening in real time, and can achieve precise flow regulation with the turbine box, eliminating the blind operation risk of traditional concealed stem valves.
\n3.Quick groove installation
\nClamp-type groove connection, no welding or flange matching required, installation time is reduced by 60%, supports pipeline thermal expansion and contraction displacement compensation, and reduces system stress.
\n4.Double sealing insurance
\nThe valve stem adopts copper alloy + O-ring sealing surface to ensure no leakage hazards.<\/p>\n

FEATURES<\/h2>\n

1.Wide temperature range: 0\u2103\uff5e80\u2103.
\n2.Strong pressure resistance: PN16\uff5ePN25.
\n3.Long life: Open and close \u2265500 times without wear.
\n4.Low torque: valve stem trapezoidal thread + bronze nut, operating force reduced by 40%.<\/p>\n

APPLICATION<\/h2>\n

1. It is used as a cut-off device on the fluid pipe line in the construction.
\n2.urban environmental protection.
\n3.Petrochemical.
\n4.Medicine.
\n5.Food.
\n6.Metallurgy.
\n7.Textile.
\n8.Power and other industries (not suitable for throttling).<\/p>\n

WORKING PRESSURE<\/h2>\n
