Y Type Bellow Sealed Globe Valves

Detailed Product Description

Y TYPE BELLOW SEALED GLOBE VALVE TO DIN

Features

Bellow sealed globe valve acc.to DIN 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 PN16-PN40 and working tempreture of -29-350^oC

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 quenched and tempered,and its surface is treated by nitriding 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. Small flowing resistance and low pressure drop.
7. The part material,flange and butt weld end dimension may be selected according to current operating condition and users' requirement,so that meeting the requirement of various engineering.
