    The Flowserve FlowTop control valve is a high-performance, general application valve paired with the high-thrust FlowAct pneumatic diaphragm actuator. Its modular design, which uses the same body with different bonnets, trims, and actuators, reduces spare parts and provides an interchangeable valve suitable for a broad range of industries and applications.

     

    The FlowTop valve operates in temperatures ranging from -200°C to +538°C (-328°F to +1000°F) depending on the selected material. It features precise machined plug contours and long stroke lengths for excellent control performance, and it allows easy upgrades from standard trims to low noise or cavitation control trims.
