Bürkert Type 2000 (SKU 142616) is a pneumatically operated 2/2-way angle seat valve designed for the controlled flow of liquid and gaseous media. This externally piloted valve features a stainless steel body with a G 3/8 internal thread and a PTFE seat seal. It operates with Control Function B (normally open) and is suitable for operating pressures up to 16 bar and medium temperatures ranging from -10 °C to +185 °C.

High flow rates are attained with the virtually straight flow path. The reliable self-adjusting packing gland provides high sealing integrity. This maintenance-free and robust valve is optimized for decentralized process automation and can be retrofitted with a comprehensive range of accessories for position indication, stroke limitation, or manual override.

Control Function

Control function B (CF B)

• Pneumatically operated 2/2-way on/off valve
• Flow direction below seat
• Normally opened by spring force

Risk of water hammer

When flow inlet over seat, do not use angle seat valve for liquid media due to the risk of water hammer. This specific model (142616) is designed for flow direction below seat, which is suitable for liquids, steam, and gases.
