252 Five RÖTELMANN Shut-off and control technology R HYDRAULIC VALVES 2-WAY BALL VALVES Rötelmann’s 2-way ball valves are made from stainless steel, steel or aluminium and can be used at up to 1500 bar. They offer numerous variants for different intended applications. For example, the 2-way ball valves can be automated with pneumatic, electric or hydraulic actuators, and can be supplied with limit switches, proximity switches, locking devices and detends. So that everything fits together properly, they also produce all common types of thread, flange and plug connectors, as well as ball valves, for manifold mounting and for manifold insertion in cartridge form. • Nominal diameters from 4 to 127 • High grade materials like steel, stainless steel or aluminium for pressures up to 1500 bar (21,750 psi) • Zinc nickel plating gives up to 1000 hours resistance in salt spraying test • With optional pneumatic, electric or hydraulic actuator • Also available with limit switch, proximity switch, locking device or detent MULTI-WAY BALL VALVES Rötelmann’s multi-way ball valves are produced in nominal widths DN 4 to DN 65, with floating ball or trunnion ball. DN 65 only for manifold valves, threaded connections up to DN 50. They are also available for pipe mounting, manifold mounting and manifold insertion. The enclosures are made from stainless steel, steel or aluminium and are designed for use at up to 500 bar. For precise automatic control, they can optionally supply the multi-way ball valves with pneumatic, electric or hydraulic actuators, as well as limit switches, proximity switches and locking devices. • Nominal diameters from 4 to 65 • Nominal pressures up to 500 bar (7250 psi) • Zinc nickel plating gives up to 1000 hours resistance in salt spraying test • With optional pneumatic, electric or hydraulic actuator • Also available with limit switch, proximity switch, locking device or detent VALVES Rötelmann’s needle valves, check valves and flow control valves have thread connections from DN 4 to DN 50. Their enclosures and spindles, or threaded connectors, are made from steel. The flow in Rötelmann’s check valves is not reduced. CHECK VALVES • With threaded connector: Steel DN 4 – DN 50 • Full flow, no reduction • Custom orders upon request • Opening pressures: 1 bar for DN 4 and DN 6, 0.5 bar for all other sizes • Available with BSP connector ISO 228-1 and with connectors for light and heavy range series according to DIN 2353 • Also available in stainless steel NEEDLE VALVES • DN 4 – DN 50 • Body and spindle of steel, rotary aluminium knob (closed design) • PN: 350 bar • Custom orders upon request • Also available in stainless steel FLOW CONTROL VALVES • DN 4 – DN 50 • Body and spindle of steel, rotary aluminium knob (closed design) • PN: 350 bar • Opening pressure: 0.5 bar • Custom orders upon request • Also available in stainless steel All technical information and dimensions subject to change without notice.
