Model HPS Pneumatic Top-guided High-Pressure Single-Seated Control Valves are design for high temperature, high pressure services. The compact valve body, having a S-shade flow passage that features low pressure loss, allows a large flow capacity and rangeability.
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 ANSI Standard. The actuator integrated with simplest mechanisms utilizes a compact yet powerful diaphragm actuator loaded with multiple springs. The HPS Valves are widely applicable for reliable control of high temperature, high pressure process
lines.
