Description
Model HTS Pneumatic Top-guided Single Seated Control Valves are designed for heavy-duty service. The compact valve body, having an S-shape flow passage that features low-pressure loss, allows a large flow capacity, rangeability, and high accuracy flow characteristics.
The valve plug is highly vibration-resistant as it is held by a top guide section which has a large sliding area. The flow shut-off performance complies with the IEC or JIS Standards. The actuator integrated with the simplest mechanisms utilizes a compact yet powerful diaphragm actuator loaded with multiple springs.
The model HTS Valves are widely applicable for reliable control, with high shut-off performance, in high or low temperature, high-pressure process lines.
