Burkert 360685 Type 2300 pneumatically operated 2-way angle seat control valve ELEMENT. In line with Bürkert’s philosophy for modular valves and sensors, the construction of the Type 2300 angle-seat valve fulfills tough criteria for process environments. Unrivalled cycle life and sealing integrity is guaranteed by the proven self-adjusting packing gland. The parabolic trim results in a flow characteristic approximately 35% larger than conventional control valves. It is available in either stainless steel on stainless steel or with a durable PTFE seal for tight shut-off. This system has been engineered for reliable accurate control in applications where high flow rate is an advantage.

Installation & Maintenance

Safety Instructions

Risk of injury from high pressure in the system! Before loosening lines and valves, turn off the pressure and vent the lines.

Risk of injury due to improper installation! Installation may be carried out by authorised technicians only and with the appropriate tools!

Preparatory work:

• Clear impurities from pipelines (seal material, metal chips, etc.).
• Ensure that pipelines are aligned before connecting the valve.
• Note the flow direction (flow direction always below seat).

Installing the body (Welded connection):

• When welding the valve body into the pipeline, the control unit must not be installed.
• Weld or bond valve body in pipeline system.

Note

Damage to the seat seal or seat contour! When installing or removing the actuator, the valve must be in the open position. For control function A, pressurise the pilot air port 1 with compressed air (5 bar) to open the valve.
