Partial half jacketed ball valve

Partial half jacketed ball valve introduction
Partial half jacketed ball valve is produced in carbon steel and different types of stainless steel materials, Other special materials are available upon special request. which no need enlarge the connection flange, the jacket is half design.PTFE soft seated jacketed ball valve gives Zero Leakage, tight Shut-Off and Low Torque with easy smooth operation at temperature ranging from -20° C. to +220° C. metal seated jacketed ball valve is also can be produced for high temperature medium.

The Jackets assure consistent valve Heating or Cooling of the process media to prevent crystallization or seizing of flow media. Steam,hot oil can be used as carrier for heating media. Following quality assurance rules, every valve is tested again after the Jackets have been welded (Fabricated) to the body. Jacket Hydraulic & Air Test is carried out at 6 bar.

which no need enlarge the connection flange, the jacket is half design. operation: thermal insulation jacket ball valve is generally supplied with manual hand lever or gear unit operated, depending on valve size. We also supply steam jacketed Ball Valves with either Pneumatic or Electrical actuator operated for automation.

One Piece Cast Steel Body

Floating Ball, Full Bore or Reduced Bore

Fire Safe Design

Anti-Static Device

Blow-Out Proof Stem

Drain Plug

Locking Device

Self-Lubricated, Maintenance Free Bearings

Underneath stem packing prevents coagulable fluids from coagulating at the stem rotation position. 

Self-Tightening threaded seats, easy demounting and maintaining

Jacket welded from shaped steel pipe, with high strength low weight

Aligned flow passage of valve and pipeline, optimum flow rate

Sufficient full flow jacket space for thermal/cold media accommodating, assures reliable insulating for pipe fluids.

Flange size is bigger than that of valve nominal size.

Insulating media port ends can be flanged.
