Burkert 186972 – Type 2000 Pneumatic 2/2-Way Angle Seat Valve, Stainless Steel, G 1/2, 25 bar
The Burkert 186972 (00186972) is a Type 2000 CLASSIC pneumatically operated 2/2-way angle seat valve in control function A, normally closed by spring force. Bürkert lists it with these features:
- Stainless steel body with G 1/2 internal thread (DN 15)
- PTFE seat seal
- Operating pressure of 0 – 25 bar
- Medium temperature from -10 to +185 °C
The valve combines a pneumatic piston actuator with a flow-optimised angle seat body. This gives high flow rates and a long service life in steam, water, gas and chemical lines.
A DN 15 Valve Rated to 25 bar
In Bürkert’s fluidic data for G-thread DN 15 bodies with control function A and PTFE seat, the operating pressure depends on actuator size:
- Ø 40 mm actuator: 15 bar
- Ø 50 mm actuator: 16 bar
- Ø 63 mm actuator: 25 bar
The 25 bar rating of the 186972 therefore corresponds to the Ø 63 mm (E) actuator. For that combination, Bürkert specifies a Kv value of 5.4 m³/h and a minimum pilot pressure of 4.5 bar. The 25 bar rating applies to flow below the seat, which is the direction Bürkert approves for liquids, steam and gases. Flow above the seat is limited to gases and steam because of the water-hammer risk with liquids.
