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 excellent flow characteristic accuracy.
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 fluids 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 becomes.
The flow path is simple and typically used for low-in, side-out configurations, which helps ensure better stability during regulation.

Features

　　The valve body is made from forged steel, and the valve seat features an integral sleeve-type design, which protects the valve body from damage caused by flash vaporization and cavitation. The valve core and seat are built with hard alloy overlay welding, offering excellent resistance to erosion and cavitation. This valve is ideally suited for use in the chemical and petrochemical industries, particularly in high-pressure fluid control applications within synthetic ammonia and urea production processes.
