Product Description

DIN bellows seal gate valve 

TECHNICAL DATA

Application
Steam, thermal oil, rank poison and strong corrupt gas and liquid medium.Advantage

• 1.Bellow seal element. The key part of bellow sealed globe valves is mental bellow. It is the connection between cover and stem with automatic roll welding. The mental bellow can keep the stem part no leakage.
• 2.Double seal design(bellows+packing). Bellow and packing can protect against leakage and provide a excellent seal.
• 3. Grease nipple. It can direct lubricate the stem, nut and sleeve.
• 4. Ergonomic hand wheel. It provide longer service life and easier operation.

When bellows globe valve is open, the bellows is compressed, the adverse sealing pair of valve stem and valve cover limits stroke of valve stem to prevent that deformation of bellows exceeds its own limits and causes damage. 3. The valve stem of bellows globe valve adopts double seal structure of bellows and stuffing to guarantee no leakage sealing at valve stem. 4. The valve is particularly applicable to industrial pipeline for flammable, explosive, toxic, strong penetrability, nuclear radiation, nuclear power project and ship confined space and other special medium and severe conditions.
