The FlowTop control valve is a high-performance, general application valve coupled with the high-thrust FlowAct pneumatic diaphragm actuator. The modular design allows by using the same body with different types of bonnets, trims and actuators, the reduction of spare parts and offers an interchangeable valve for a broad range of industries and applications.

The FlowTop valve is capable of operating within temperature ranging from -196°C up to +538°C (-321°F up to +1000°F) according to the selected material.

Precise machined plug contours and long stroke lengths results in an excellent control performance. Easy upgrade from standard trims to low noise- or cavitation control trims. Up to 17 kvs/cv-values available per size, allows a wide range of process conditions for each size.

The FlowTop control valve offers a sturdy plug head guide for minimizing vibrations and wear.  Due to the design of a profile-ring - very reliable sealing between body and seat, easy maintenance, no machining required of the body seat area when changing the seat.  With the high quality, live loaded TA-Luft desig (PTFE or Graphite packing) we reach a leakage class
better than 10-8 mbarl/s
