Valves
ANSI Bellows Seal Gate Valves
ANSI Bellows Seal Gate Valves
Summary
Gate valve with bellow seal acc.to ANSI is applicable to the cutting and connection of pipelines medium that are used in various industries such as petroleum ,chemical industry, pharmacy ,chemical fertilizer, electric power industry etc under nominal pressure of CLASS150-900LBS and working temperature of-29~350°C
Features
1. This product has logical structure, reliable seal, excellent performance and nice design.
2. The seal surface is build-up welding with Co hard alloy, which is attrition-resistant, corrosion-resistant, has good friction resistant and long life.
3. The stem is quenched and tempered, and its surface is treated by nitrogen treatment, thus it has good corrosion resistant and friction resistant.
4. It has double seal capability, thus is more reliable.
5. The stem may show the position of lift, thus it is clearer.
6. The part material, flange and butt weld end dimension may be selected according to current operating condition and uses' requirement, so that meet the requirements of various engineering.
