Product Name: Model HLC

Product Description

OVERVIEW: - Model HLC Small-Port Cage Guide Type Single Seated Control Valves are designed for high differential pressure Service where fluid normal differential pres sure exceeds 30kgf/cm² or for heavy-duty service where flashing/cavitation may occur. Further, they are ideal for preventing erosion from the valve body, because their guides are sturdy and the valve body is protected by a cage. The compact valve body, having an S-shaped flow pass age that features low pressure loss, allows a large flow capacity and rangeability. The valve plugs are available in a wide range of Cv values. The flow shutoff performance complies with simplest mechanisms, utilizes a compact yet powerful diaphragm actuator loaded with multiple springs. The HLC Control Valves are widely applicable for reliable control of small flows in high- or low-temperature, high differential pressure process lines.
