Burkert 463624 – Type 2000 Pneumatic 2/2-Way Angle Seat Valve, Normally Open, Stainless Steel, 1″ NPT
The Burkert 463624 (00463624) is a Type 2000 CLASSIC pneumatically operated 2/2-way angle seat valve in control function B, which means normally open by spring force. Bürkert lists it with these features:
- Stainless steel body with 1″ NPT internal thread (DN 25)
- PTFE seat seal
- Operating pressure of 0 – 16 bar
- Medium temperature from -10 to +185 °C
Unlike the more common normally closed versions, the 463624 stays open when the pilot air is removed. Applying pilot pressure to the actuator closes the valve.
When to Choose a Normally Open Angle Seat Valve
Control function B is the right choice where the process must keep flowing if air or power fails. Typical examples are cooling water, flushing lines, and circuits that must not be shut off by a loss of control air. The valve operates with flow below the seat, the direction Bürkert approves for liquids, steam and gases. In control function B, the pilot pressure needed to close the valve rises with the operating pressure. Bürkert publishes pilot-pressure diagrams for each actuator size to size the air supply.
DN 25 at 16 bar
In Bürkert’s fluidic data for DN 25 threaded bodies in control function B, the actuator size sets the pressure limit:
- Ø 50 mm actuator: 16 bar
- Ø 63 mm or Ø 80 mm actuator: 25 bar
The 16 bar rating of the 463624 matches the Ø 50 mm (D) CLASSIC actuator. For that combination, Bürkert specifies a Kv value of 15 m³/h (water), with a G ¼ pilot air port.
