Keluli palsu sepenuhnya dikimpal injap bola-PE TYPE

Materials Available:

Body: ST37.8 / P235GH/ 20#

Ball: F304 / F316 ( Option upon request )

Seat: PTFE+C / Nylon / PEEK. etc.

Main Characteristics:

One-piece welded body & End piece connection pipe (Connection dimension to ASTM / EN / KS / JIS / GOST Standard. etc will be available.

Bubble tight excellent sealing with PTFE+C seats.

Pre-loaded seat springs ensure leak-tight at low pressure and reduce valve operational torque.

Anti blow-out stem.

Double O-rings ensure the stem sealing and are replaceable.

Stem dry bearing, metal with PTFE coating having self-lubricating capabilities. (Additional lubricant unnecessary.

Other Characteristics:

1. the overall body structure welding, there will be no external leakage.

2. the valve seat composed by a PTFE sealing ring and springs which has a strong adapt ability to changes of pressure and temperature, within the using range there will be no any leaks.

3. stem leakage prevention structure, the bottom of the stem has a PTFE seal the puncture, there are two O-rings above, composed of two PTFE gaskets ensure no leakage.

4. the same body material and pipe material, stress will not appear uneven, it will not because of the earthquake and the vehicle passes through the ground sometimes cause extrusion.

5. the body is light and easy to keep temperature not down.

6. we can adjust the body length and stem height according to construction and design requirements of the pipeline.

7. the ball’s machining precision is very high easy to operation, no adverse interference.

8. can use welded and flanged two kinds connection type.

Application:

Used in city gas, urban heating, petrochemicals, shipbuilding, steel, pressure regulating stations, power plants, and other pipeline equipment.
