Description

Purpose

Gate valve bellow seal 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 class 150-1500LB and working temperature of-29~350°C

Structural 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 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. The part material, flange and butt weld end dimension may be selected according to current operating condition and users’ requirement, so that meeting the requirements of various engineering.

Bellow Sealed Gate Valve FAQs

1. What is a bellow seal gate valve?
