Burkert Type 2100 pneumatically operated 2/2-way angle seat valve is specially optimized for decentralized process automation and fulfills the 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 interface.

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 characterized by its compact and smooth design, integrated pilot air ducts, protection classes IP65/67, NEMA Type 4X, and high resistance to chemicals.

Key Features

• High flow rates
• Long service life
• Easy integration of automation units with ELEMENT
• Flow-optimised stainless steel valve body with sleeve, clamp or weld connection
• Suitable for steam

Control Functions

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.

Flow direction below seat for liquids, steam and gases

Control function A (CF A): Pneumatically operated 2/2-way on/off valve. Flow direction below seat. Normally closed by spring force.

Control function B (CF B): Pneumatically operated 2/2-way on/off valve. Flow direction below seat. Normally opened by spring force.

Flow direction above seat for steam and gases

Control function A (CF A): Pneumatically operated 2/2-way on/off valve. Flow direction above seat. Normally closed by spring force.

Safety Instructions for Ex Area

DANGER

Explosion hazard due to electrostatic discharge! If statically charged devices or persons discharge suddenly, there is an explosion risk in the potentially explosive area.

• Take appropriate measures to ensure that no electrostatic charge can build up in the potentially explosive area.
• Only clean the device surface by wiping it gently with a damp or antistatic cloth.
• Ground the actuator and the valve body.
• If a plastic valve body is used, ground the actuator separately.

TIP

Networking and combination The angle seat valve Type 2100 can be combined with the position feedback Type 8690/8697 and the control head Type 8691/8695 to form the valve system on/off ELEMENT Type 8801-YE.
