Applicable temperature: -196～450℃;
Drive mode: manual, pneumatic, electric, etc.;
Nominal diameter: 1/2"～48";
Applicable medium: water, gas, oil, natural gas and acid-base corrosion medium.
Nominal pressure or pressure level: PN1.0-42.5MPa, ANSI CLASS 150-2500, JIS10-20K
Connection ends: flange, butt welding, socket welding, etc..
Applicable working condition: It is suitable for general working media such as water, solvents, acids and natural gas, but also suitable for media with severe working conditions, such as oxygen, hydrogen peroxide, methane and ethylene, etc. It is widely used in various industries. Forged steel American standard valves are mainly used in various high-pressure medium transportation pipelines in chemical industry, metallurgy, petroleum, pharmaceutical and other industries.
Forged steel trunnion mounted ball valve: The soft seal ring is inserted into the steel ring. The steel seat is also machined with a sealing surface. The radial and back of the steel seat are provided with a "0" ring to ensure that the medium does not leak.
The valve stem is a bottom-mounted design, and thrust bearings are provided at the shoulder to reduce the operating torque.
The density of the material is much greater than the density of the casting. It is especially suitable for the manufacture and processing of high-pressure ball valves. The high-pressure forged steel ball valve closing member rotates around the center line of the valve body to achieve opening and closing.
The seal is embedded in the stainless steel valve seat, and a spring is provided at the tail end of the metal valve seat. When the sealing surface is worn or burned, the valve seat and the ball are pushed to form a metal seal under the action of the spring.
It has a unique automatic pressure relief function. When the medium pressure of the valve exceeds the preload of the spring, the valve seat at the outlet backs away from the ball to achieve automatic pressure relief. The valve seat automatically resets after pressure relief.
Forged steel ball valve: The fluid resistance is small, the ball valve is the smallest fluid resistance in all valves, even the reduced diameter ball valve, the fluid resistance is quite small. The switch is quick and convenient. As long as the valve stem rotates 90°, the ball valve completes the fully open or fully closed action, and it is easy to achieve fast opening and closing. Good sealing performance.
