1.8 Opening and closing forces required

The values specified in the tables apply to a seat/plug
material of modified PTFE.
With  other  materials,  e.g.  PTFE/carbon,  higher
closing  forces  are  required.  Please  inquire  at
manufacturer's.

If the maximum

p is < p2, p2 is used in the tables.

observe the application limits acc. to the pressure-
temperature diagram in

Section 1.4

♦

mechanical travel stop

is required in the area

marked.

It is provided when

p > 10 bar / 145 psi to Seat-Ø 15-50 mm

p > 6 bar / 87 psi to Seat-

Ø ≥ 65 mm

1.8.1 PTFE - Standard bellows

Opening forces

The opening forces remain below the closing forces and are therefore not shown.
