The BURKERT Type 2101 globe valve (Model 20063683) is specially optimised for decentralised process automation and meets all practical requirements even under difficult operating conditions. 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 characterised by its compact and smooth design, integrated pilot air ducts, protection classes IP65/67, NEMA Type 4X, and high resistance to chemicals. The 20063683 variant specifically features a DN 15 flange connection, stainless steel body, PTFE seat seal, and operates with control function A (normally closed).

Features

• Compact design
• Long service life
• Easy integration of automation units with ELEMENT
• Stainless steel valve body with flange, sleeve or welded connection
• Suitable for steam

Structure and Function

The globe valve consists of a pneumatically actuated piston actuator and a 2-way body. The actuator is made from polyphenylene sulphide (PPS) or stainless steel.

Control Functions

Depending on the variant, the valve seat is closed in the direction of or against the medium flow. Spring force (CFA) or pneumatic pilot pressure (CFB and CFI) generate the closing force on the swivel plate.

• Control function A (CFA): Pneumatically operated 2/2-way on/off valve. Flow direction below seat. Normally closed by spring force.
• Control function B (CFB): Pneumatically operated 2/2-way on/off valve. Flow direction below seat. Normally opened by spring force.
• Control function I (CFI): Actuating function via reciprocal pressurisation.

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.

Installation Notes

• The installation location must be easily accessible and provide sufficient clearance for installation, removal and maintenance of the device.
• The globe valve can be installed in any position, preferably with the actuator facing upwards.
• Ensure that the pipes are aligned before connecting the valve.
• Observe the direction of flow. Observe the information on the type label.

TIP

The position of the ports can be seamlessly aligned by turning the actuator 360°. When turning the actuator, the valve must be in the open position to avoid damage to the seat seal or seat contour.
