Wholesale of Single seat regulating valve

Single seat Regulating valve is a commonly used fluid control equipment in industrial automation control systems, mainly used to regulate parameters such as fluid flow rate, pressure, and liquid level. It drives the valve core to move inside the valve body through the actuator, changing the flow area between the valve core and the valve seat, thereby achieving precise control of the fluid.

Working principle:

The control system sends a signal to the actuator, driving the valve stem to move the valve core up and down, changing the flow cross-sectional area. When the valve core approaches the valve seat, the flow area decreases and the flow rate decreases; On the contrary, the traffic increases.

Single seat regulating valve is a commonly used precision control valve in industrial pipeline systems. Its core advantages are reflected in sealing performance, regulating accuracy, and structural characteristics, as follows:

1. Excellent sealing performance with extremely low leakage rate

Single seat structure: The valve core and valve seat are matched one-to-one, and the sealing surface is in close contact, especially suitable for scenarios with strict sealing requirements.

Optional sealing form:

Metal hard seal: using hard alloy overlay welding, pressure and wear resistance, leakage level can reach ANSI B16.104 V level.

Soft seal: The valve seat is embedded with materials such as polytetrafluoroethylene to achieve zero leakage, suitable for corrosive or clean media.

2. High adjustment accuracy and stable control

Force balance: The single seat structure valve core is less prone to oscillation at small openings, and with high-precision actuators, it can achieve precise flow control.

Optional flow characteristics: By designing the valve core shape, it can match linear, equal percentage, fast opening and other flow characteristics to adapt to different process curve requirements.

3. Compact structure, easy installation and maintenance

Single seat design: The valve body has a simple flow channel, few parts, and is not prone to depositing media, making it suitable for fluids with high viscosity or low particle content.

Low maintenance cost: No need to frequently adjust the packing gland, reducing downtime.

4. Suitable for various extreme working conditions

Wide pressure range: can withstand high pressure difference, but attention should be paid to the unbalanced force of the valve core.

Strong temperature adaptability: By selecting materials that are resistant to high or low temperatures, it can be used in media ranging from -196 ℃ to 450 ℃.
