Ball valves

A ball provided with a bore and guided by sliding shells in a geometrically adjusted housing is called a ball valve. The 90° angle opens or closes the way.

Construction:

• 1-part ball valves, the low-cost variant, without exception manually operated
• 2-part ball valves, consisting of 2 body halves, automatable
• 3-part ball valves, consisting of centre piece and 2 connection ends, automatable

Materials Body:

• Nickel-plated brass
• Cast steel, forged steel
• Stainless steel

Materials seals

• PTFE (reinforced with glass fibre, carbon)
• FKM

Connection types:

• cylindrical internal thread/external thread to DIN 2999, ISO 228
• tapered female thread NPT according to ASME/ANSI B20.1
• Welding ends to DIN 3239, ISO 4200, DIN 11850

Pressure ratings:

• PN10
• PN16
• PN40
• PN64
• PN100
• ANSI-ASME16.5 class 150, class 300, class 600, class 1200

Installation lengths (in mm) EN 558-1

Depending on the type of connection, the installation lengths are standardised.
For flange fittings, the overall length EN558-1 (formerly DIN3202 F1, F4, F5 or DIN3202 K1 for wafer fittings) is used.

Use of ball valves manually, pneumatically or electrically operated:

• Shut-off and release of liquefied cryogenic gases up to -197°C for the food industry
