Burkert 466611 (Type 2100) is a pneumatically operated 2/2-way angle seat valve specially optimised for decentralized process automation. It fulfils tough criteria in process environments and allows easy integration of automation units in all expansion stages, from electrical/optical position feedback to pneumatic control and integrated fieldbus interfaces. Maximum service life and tightness are achieved by the proven self-adjusting V-seal packing gland.

Key Features:

• High flow rates
• Long service life
• Easy integration of automation units with ELEMENT
• Flow-optimised stainless steel valve body
• Suitable for steam and vacuum applications

Control Functions and Flow Direction

The 466611 model features Control Function A (CFA), meaning it is a pneumatically actuated on/off valve that is normally closed by spring force in the rest position.

Flow Direction Below the Seat

Only use flow direction below the seat for liquid media, gases, and vapours. As the medium is present under the swivel plate, the operating pressure contributes to the opening of the valve.

Flow Direction Above the Seat

Only use flow direction above the seat for gases and vapours. As the medium is present above the swivel plate, the operating pressure contributes to the closing of the valve and supports the sealing of the valve seat.

WARNING

Risk of damage due to bursting pipes and bursting equipment when the flow is above the seat. In the case of liquid mediums, water hammer can occur causing pipes and the device to burst. Do not use valves with flow above the seat for liquid mediums.

Product Identification

Safety and Installation

DANGER

Danger due to lubricant Lubricant may contaminate the medium. There is a risk of explosion in oxygen applications. Only use lubricant that is permitted for the medium.

TIP

The position of the pilot air ports can be seamlessly changed by turning the actuator 360°. To prevent damage, the valve must be in the open position when the actuator is turned.

WARNING

Contaminated pilot air The control exhaust air of the device can be contaminated with lubricants and damage the health of people and the environment. Dissipate control exhaust air appropriately. Only use fresh air for generating compressed air for the device.
