HLC Single seated control valve

HLC Single seated control valve

Overview

HLS Single seated control valve with a compact valve body and an S-shape flow way features with low pressure loss, large flow capacity, wide range ability and high-precision flow characteristics. The design of valve complies with IEC60534-2-1-2011 standard and the leakage complies with ANSI FCI 70-2-2013 standard. The compact size and large output force are available when the control valve is combined with multi-spring diaphragm actuator or cylinder actuator.

It is complies with the GB/T4213-2008 standards.

Work principle

HLS Single seated control valve When the actuator is linearly displaced, the valve core is driven by the valve rod to move. It is connected with the valve body by bolts and is used to locate the center of the valve stem and valve core. The valve seat and the upper valve cover are used to ensure the center position of the valve core and the valve seat, and when the valve core moves, change the flow area of the fluid, thereby changing the manipulated variable and realizing the function of adjusting the fluid flow.

Feature

1. The leakage is small, and it is easy to achieve strict sealing and cutting.

2. The allowable pressure difference is small

3. The flow capacity is small
