Reliable body and seat sealing
3 mm (1 /8“) thick virgin PFA body lining
High permeation resistance
Translucent, optimum quality assurance
Pressure-bearing body made of ductile
cast iron EN-JS 1049 (0.7043)/ASTM A395,
absorbs system and pipe forces.
Permanent body flange sealing
Effective even under the most frequent thermal cycle conditions
Sealing zone (3a) with full liningthickness
Labyrinth-like sealing (3b) maximizes surface pressure.
Body pieces position themselves properly by means of the cup and cone shapes (3c) of each piece. Metal centering (3d) withstands lateral and
angular pipe forces.
Almost metal-to-metal flange contact (3e) in the circumference area controls the effects of temperature variations.
One-piece ball/stem design
Stainless steel core
Eliminates individual plastic lined mating parts for higher pressure/temperature ratings and optimises operational safety.
Al2O3 (99,7 %) ceramic ball option
Energised PTFE seat rings
provide a permanent spring load onto the ball and ensure of gas-tight sealing.
Time-tested maintenance-free stem seal
Outstanding long-life seal performance
Gas-tight to EN 12266, leakage rate A
Spring gland follower ensures of tightness even with changing conditions.
Visual inspection of sealing load
Manually adjustable from outside
Universal ISO 5211 mounting dimensions
External corrosion protection
Body epoxy coated. Packing gland, lever, lever stop, nuts and bolts stainless steel. Optional ASTM A193/B7M bolting.
