About 2-way ball valves

Ball valves shut off a line with a quarter turn and give full bore when open. The range covers nominal sizes from DN 5 to DN 100 and pressure ratings from PN 12 to PN 100, with threads from G 1/4 to G 2 and Rp 1/2 to Rp 1 1/4. Alongside hand-operated versions there are pneumatically and electrically actuated variants.

What matters when choosing

• Nominal size DN 5 to 100 and pressure rating PN 12 to 100: both follow from line size and system pressure.
• Thread type: parallel G threads to DIN EN ISO 228-1 and tapered threads to ISO 7-1 or DIN EN 10226 are both represented. The standard has to match the mating part in the line.
• Actuation: besides hand levers there are pneumatic actuators in double-acting, single-acting spring-to-close and single-acting spring-to-open form, plus electric actuators for 230 V AC / 50 Hz and 24 V DC. Spring-return units move to a defined position if control air is lost.
• Body material: nickel-plated, chrome-plated or bare brass, stainless steel 1.4401 and 1.4408, aluminium and powder-coated aluminium, and the plastics PA and PA6/PC.
• Position feedback: versions are available with microswitch, with inductive switch and with inductive switch in ATEX design.

Typical applications

• Isolating compressed air lines for maintenance and modification work
• Shut-off and changeover points in water and cooling circuits
• Process lines carrying neutral gases and liquids
• Remote isolation using pneumatic or electric actuators
• Shut-off points that report their position back to the higher-level control

Threads follow DIN EN ISO 228-1, DIN EN 10226 or ISO 7-1, mounting plates follow ISO 5211. Depending on version, actuators and switches reach IP 66/67 or IP 68 to DIN EN 60529.
