Pneumatic Top-Guided Single Seated Control Valves are engineered for robust applications. Featuring a compact valve body with an S-shaped flow passage, they minimize pressure loss while maximizing flow capacity, rangeability, and precise flow characteristics. The valve plug, securely guided from the top, ensures exceptional vibration resistance with a large sliding area. Shut-off performance meets IEC or JIS Standards, supported by a compact diaphragm actuator equipped with multiple springs for efficient operation. These valves are widely used for reliable control in both high and low temperature, high-pressure processes.
