مشخصات:
Vacuum resistance
Design and manufacturing of our 2-piece and 3-piece ball valve allow a vacuum capability of at least 10-3 mbar (0,75 10-3 Torr).
PED directive
According to Pressure European Directive (PED) 97/23/ CE, all our ball valves are controlled during the production process. A final hydrostatic pressure test is achieved before dispatch or warehousing.
Our tests are conducted according ISO 5208 international standard.
Fugitives Emissions
Our valves are tested according TA LUFT 02/27/1986 (Pt 3.1.8.4) requisition.
Measure show leakage rate much lower than the level requested EN ISO15848-2 by regulations such as VDI 2440_2000.
Test pressure of the ball sealing
The upstream/downstream leakage rate, (in-line leakage), is the sealing between the ball and the seats.
• Ease of installation without alignment of the end pieces
• Orientation of the valve body through 360°
• Elimination of the stresses due to faulty alignment
Design according NF EN 12516-1, DIN 3841, AINSI B16.34
Antistatic gland packing according to ISO 7121, NF EN 1983
Gland packing (6) in PTFE+ carbon + graphite (DN 2″)
Primary sealing with thrust seal (4) in PEEK reinforced PTFE
Secondary sealing with a “V-ring” packing (6) to allow sealing under pressure coming from the valve body
Gland in stainless steel (24)
Wear compensation by the mean of a pair of spring washers (7)
Built-in body seals to guarantee internal/external tightness.
Seats profiles designed for upstream/ downstream sealing.
Seats elasticity to absorb pressure stress.
Progressive bearing to optimize operating torques.
Ruff to avoid the seat to be taken away when upstream pressure is higher than downstream pressure
