DESCRIPTION

nnnn

• High quality industrial butterfly valve, EN 10204

nnnn

3.1 certificate, CE/PED and ATEX approvals are avail-

nnnn

able.

nnnn

• Unique wave shaped seat reduces torque and

nnnn

prolongs service life.

nnnn

• Seat vulcanised to a replaceable back-up ring com-

nnnn

pared to a traditional replaceable seat has several

nnnn

advantages: Exact tolerances produce 100 % tight-

nnnn

ness and prolong service life - Suitable for vacuum

nnnn

and high flow velocity - Mounting between flanges

nnnn

without seat displacement.

nnnn

• Extensive choice of materials provides for many

nnnn

applications. Strong handle in steel or stainless steel.

nnnn

• Two-piece stem and streamlined disc result in

nnnn

high Kv-value and less turbulence.

nnnn

• ISO 5211 mounting flanges and stem enable

nnnn

direct mounting of actuators without the use of

nnnn

brackets or couplings.

nnnn

Square transition between stem and disc ensures

nnnn

peak reliability.

nnnn

• 3-piece plain bearing reduces friction and prolongs

nnnn

service life.

nnnn

Self-centering solution during mounting covers

nnnn

many standards (see general).
