Forged steel gate valve is designed and manufactured according to JB/T7746, API602, ANSI B16.34 standards, using the latest grinding and forging technology. Suitable for Class150~2500, working temperature -29 ~ 425 ℃ (carbon steel), -29 ~ 550 ℃ (heat-resistant steel) or -196 ~ 600 ℃ (stainless steel) of the small diameter pipe. Valve design is compact, beautiful appearance. Different materials are selected, which can be applied to water, steam, oil, nitric acid, acetic acid, oxidative media, urea and other media respectively.
The valve is used in the pipeline system of power station, nuclear power station, metallurgy, mining, chemical industry, hydropower and other industries, mainly to cut off or connect the medium in the pipeline, with the help of the handwheel on the upper end of the stem nut to apply a certain torque to the gate, so that the gate moves up and down, to achieve the opening and closing of the valve.
Product features
1：The gate structure is rigid wedge-shaped single gate, the stem is equipped with inverted seal, good sealing.
2：The valve stem is heat-treated and has good corrosion and friction resistance.
3：The packing adopts graphite, reliable sealing, flexible operation, small opening and closing torque. Valve body and bonnet are bolted or self-sealing connection, the valve is full bore or reduced diameter, valve connection can be welded, flanged or threaded and other connection forms.
