HLC Pneumatic Small-Port Cage-Guided Type Single-Seated Control Valve的简单介绍

designed for high differential pressure Service where fluid normal differential pressure

HLC Pneumatic Small-Port Cage-Guided Type Single-Seated Control Valve的详细信息

Model HLC Pneumatic Small-Port Cage-Guided Type Single-Seated Control Valves are designed for high differential pressure Service where fluid normal differential pressure exceeds 2940 kPa {30 kgf/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 com- pact valve body, having an S-shaped flow passage 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 model HLC Control Valves are widely applicable for reliable control of small flows in high- or low-temperature, high differential pressure process lines.
