Description

Design and manufacture stadnard: DIN3356
Face to face: DIN3202
Flange ends standard: DIN2543-2545
Inspection and test standard: DIN3230

Purpose

Stop 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 PN1.6~16MPa 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.

DIN Bellow Sealed Globe Valve FAQs

1. What is a DIN bellow sealed globe valve used for?

A DIN bellow sealed globe valve is used to isolate or regulate flow in industrial pipelines where stem leakage must be minimized. It is commonly selected for hazardous, toxic, high-temperature, or high-value media.

2. What are the main advantages of a DIN bellows seal globe valve in industrial applications?

Its main advantage is reliable stem sealing through a metal bellows design, which helps reduce fugitive emissions and maintenance needs. This makes it suitable for demanding process systems and critical isolation service.

3. Which media is a DIN standard bellows sealed globe valve suitable for?

It is suitable for steam, hot water, thermal oil, oil, gas, chemical fluids, ammonia, and other challenging media depending on the valve material. Final media compatibility should always be checked against body, seat, and bellows materials.

4. What material options are available for a bellows seal DIN carbon steel globe valve?

Common options include carbon steel, stainless steel, alloy steel, and cast steel for the body. The bellows and trim materials can also be selected based on pressure, temperature, and corrosion resistance requirements.

5. What pressure ratings are available for DIN bellow seal globe valves?

Typical pressure ratings include PN16, PN25, and PN40, depending on the design and material specification. Higher ratings may also be available for special applications or project requirements.

6. Do you support EPC project bidding?

Absolutely. We provide full technical documentation and 24-hour response to support EPC bidding processes.
