Products Decription:

Single-piece disc/stem unit optionally fluoroplastic

Lined with pure PFA for maximum corrosion resistance and a long service life.Very low friction values and torques during opening and closing due

to the combination of a PFA disc/stem unit with a PTFE body

Optionally antistatic PFA-L

Disc/stem core made of highly torsion resistant Duplex stainless steel 1.4517/CD-4 MCu(18“-40“/DN 450-1000: SS 1.4435/316L)

Alternatively metallic

Made of precision cast stainless steel Polished sealing surfaces, therefore very low friction values

Polished disc surfaces on request

Other materials on request, e.g. Hastelloy® C, titanium

Thick-walled PTFE and TFM-PTFE lining of the valve body

TFM-PTFE lining (2“-16“/DN 50-400 with PFA-lined disc: PTFE as standard, optionally TFM-PTFE)

Lining thickness 0.12- 0.15“ (3 -3.5 mm)

High permeation resistance

Vacuum-proof

Optionally antistatic PTFE-L, PE-UHMW

Wide sealing surfaces of body

lining for reliable sealing even with mating flanges with large radii, e.g. glass-lined components.

Permanently elastic seal in the valve opening by means of silicone insert under the PTFE body lining.

Optionally FKM insert (e.g. Viton®) for use with chlorine gas for example.

Double-action, maintenancefree and self-adjusting top and bottom

stem sealing

therefore reliable even with many switching cycles and fluctuating temperatures:

primary: body lining against disc/stem shoulder

secondary: O-ring PTFE, optionally RPTFE.

Long valve neck

permits optimal heat insulation without the installation of an elevated lever, additional stem extensions on request.

External corrosion protection

Epoxy coating, nuts and bolts made of stainless steel.

Centering to ISO 5211

Chlorine electrolysis options

Specially for use with wet chlorine gas:

Elastic insert made of Viton instead of silicone Body lining made of particularly

permeation-proof, modified PTFE instead of standard PTFE Body nuts and bolts made of steel, for example, instead of stainless steel Tantalum-

coated ductile iron body.
