Summary
Stop valve with bellow seal acc.to ANSI is applicable to the cutting, switch and the adjustment of fluid.
Medium that is 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
Parabolic Plug for switch and the adjustment of fluid is available.
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 is 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
conditions and users' requirement, so that meet the requirements of various engineering.
