RHYDRAULIC 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 (21750 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 plated 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.
