Model HTS Pneumatic Top-guided Single Seated Control Valves are designed for heavy-duty service. The compact valve body, having a S-shape flow passage that features low pressure loss, allows a large flow capacity, range ability 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 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.
