Burkert 362780 Type 2100 pneumatically operated 2/2-way angle seat valve is specially optimised for decentralized process automation and fulfils tough criteria in process environments. Its unique design 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.

The highly integrated system of valve and automation unit is characterised by its compact and smooth design, integrated pilot air ducts, protection classes IP65/67, NEMA Type 4X, and high resistance to chemicals. The specific model 362780 features a stainless steel body, PTFE seat seal, weld end connection (DN 80), and operates with Control Function B (normally open).

Key Features

• High flow rates and long service life.
• Easy integration of automation units with the ELEMENT system.
• Flow-optimised stainless steel valve body with weld connection.
• Suitable for steam, water, neutral gases, alcohols, oils, and other media.

Control Functions and Flow Direction

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.

WARNING

Leaking valve seat with flow direction below seat If pilot pressure for control function B and control function I is too low or operating pressure is too high, this can cause the valve seat to leak. Comply with the minimum control pressure and the maximum operating pressure values.

Flow Direction Above the Seat

Only use flow direction above the seat for gases and vapours, and for valves with control function A (closed by spring force in rest position). As the medium is present above the swivel plate, the operating pressure contributes to the closing of the valve.

DANGER

Bursting lines and bursting device with flow direction above the seat In the case of liquid media, a pressure surge can lead to the bursting of lines and device. Do not use valves with flow direction above the seat for liquid media.

Safety Instructions for Potentially Explosive Atmospheres

DANGER

Risk of explosion due to electrostatic charge! If statically charged devices or persons discharge suddenly, there is an explosion hazard in the Ex area.

• Take appropriate measures to ensure that no electrostatic charge can build up in the Ex area.
• Only clean the device surface by wiping it gently with a damp or anti-static cloth.
• Earth the actuator and the valve body.
• If a plastic valve body is used, earth the actuator separately.

Equipment Earthing:

1. Earth the valve body: To establish equipotential bonding, earth the valve body to the pipeline system using a conductive connection.
2. Exposed metal parts that are not integrated into the valve equipotential bonding (PA) must be included in the PA by the customer via an additional PA connection.
3. Earth conductive device parts: Conductive parts must be earthed separately. Install an earthing strap clip or earthing terminal and earth via the earthing point.
