Product Details

Overview

The valve features a simple structure, with the valve body's inlet and outlet arranged at a 90° angle. It boasts low flow resistance and high valve capacity, along with a wide adjustability range and highly accurate flow characteristics.
Due to the angular control valve's dead-corner-free flow passages and straightforward flow path, it features a "self-cleaning" function, making it ideal for applications involving high-viscosity fluids, as well as those containing suspended liquids and particulate matter.
The angular regulating valve belongs to the single-seat valve category, featuring low leakage. However, since it retains the single-seat design, the larger the diameter, the smaller the allowable pressure difference.
The flow path is simple and typically used for low-in, side-out configurations, which helps ensure better stability during regulation.
