Bürkert Type 2060 pneumatically operated angle seat valve with stainless steel actuator fulfils the demands of tough process environments. Unrivalled life time and sealing integrity is guaranteed by the trusted self-adjusting packing gland. The stainless steel actuator has been designed for tough applications. Laser welding ensures it is both cleanable and robust. With a ducted exhaust air port, the actuator can be operated isolated from the environment to guarantee an optimum life time and hygiene. High flow rates are attained with the optimised stainless steel angle seat body. As part of the Bürkert process valve range, a large accessory program is available.

Networking and Combination

The Type 2060 angle seat valve can be combined with the feedback positioner Type 8697 to form the valve system on/off Type 8801-YV, or networked with modular valve islands like Type 8640 and 8644.

Control Functions

Risk of damage due to bursting pipes

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.

• Control function A (CF A): Pneumatically operated 2/2-way on/off valve. Flow direction below or above 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.
• Control function I (CF I): Actuating function via reciprocal pressurization.

Approvals and Conformities

• Explosion protection: Optional ATEX/IECEx (Category 2 device suitable for zone 1/21 and zone 2/22). EPS 18 ATEX 2 008 X / IECEx EPS 18.0007X.
• Drinking water: Suitable for use in drinking water applications (UBA assessment principles).
• Foods and beverages/Hygiene: FDA compliance, EC Regulation 1935/2004, China food GB Standards available on request.
• Others: DNV GL classification for ships and offshore units; TA Luft compliance.

Performance Specifications

Operating Limits

In addition to the maximum operating pressures, the operating range of Bürkert process valves is limited by the nominal pressure according to the relevant standard.

Optional Variants

• High-temperature variant: With PEEK packing gland and seat seal, suitable for steam and heat transfer mediums up to +230 °C.
• Water variant: Special packing gland configuration for water up to +200 °C (recommended starting at +85 °C).
• Vacuum variant: Without leakage bore, suitable for pressures down to -0.9 bar(g).
• Low-temperature variant: Suitable for minimum medium temperatures down to -40 °C.

Risk of injury from high pressure

Before working on the system or device, switch off the pressure and vent or empty the lines. Installation and maintenance may only be performed by qualified and trained personnel.
