Samson Type 3244 Pneumatic Valve

Samson Pneumatic valve Standard version designed for temperatures from –10 to +220 °C (15 to 430 °F) with pneumatic actuator.

Description


Pneumatic valve

Samson Pneumatic valve Standard version designed for temperatures from –10 to +220 °C (15 to 430 °F) with pneumatic actuator.

Principle of operation (Fig. 3 and Fig. 4)
Depending on the version, the three-way valve can be used for either mixing or diverting service.
In mixing valves, the process media to be mixed enter at valve ports A and B. The combined flow exits the valve at port AB (see Fig. 3). The flow rate from ports A or B to AB depends on the cross-sectional area of flow between the seats and plugs. In diverting valves, the process medium enters at the valve port AB and the partial flows exit at ports A and B (see Fig. 4). Note: The design of the mixing and diverting valves in sizes DN 15 to 25 (NPS ½ to 1) is identical.
