Reduced Bore Ball Valve

LYV® is a leading China quality Reduced Bore Ball Valve supplier. This valve is a High Performance Reduced Bore Ball Valve specially designed for precise control of small flow rates. This Reduced Port Ball Valve achieves more precise regulation and shut-off of fluids through a unique structure where the diameter of the ball is smaller than that of the pipe. It combines the advantage of rapid opening and closing of ball valves with the control ability of needle valves, and is an indispensable key component in instruments and meters, experimental devices, and fine chemical processes.

Product Introduction

The core design of LYV® Reduced Bore Ball Valve is actually its constricted ball. Unlike full-bore ball valves, the flow channels on its Industrial Reduced Bore Ball Valve have been precisely calculated and processed, significantly reducing the diameter. This design enables the valve to provide more precise flow gradient changes at the same opening degree, making it highly suitable as a Reduced Bore Ball Valve for Small Flow Control. Our products are made of high-quality materials and feature precise manufacturing processes, ensuring excellent sealing and durability even in small sizes, and can meet the control requirements of various harsh or high-purity medium systems.

What's the typical application scenarios of Reduced Bore Ball Valve?

●Analysis and experimental system: Widely applied in the injection, purging and pressure control pipelines of precision instruments and equipment such as chromatographs, mass spectrometers and experimental reaction vessels.

●Semiconductors and high-purity processes: Suitable for special gases (GAS), chemical delivery systems (CDS), and high-purity water systems, for reliable switching and micro-regulation of pure media.

●Small-scale industrial facilities: As a key control and shut-off valve in skid-mounted equipment, sampling systems, instrument air ducts, and small-scale chemical plants.

●Hydraulic and pneumatic auxiliary circuits: used to control system pressure, provide pilot signals for actuators, or perform fine operations such as exhaust and drainage.

Advantages of LYV® Reduced Bore Ball Valve

Precision flow control

The constricted design offers excellent flow regulation characteristics, enabling fine control from low flow to shut-off.

Compact structure design

As a Reduced Port Ball Valve, its structure is extremely compact, providing an ideal solution for equipment layouts with limited space.

High sealing grade

With floating ball or enhanced valve seat design, it can ensure bubble-level sealing even at very small diameters, preventing internal or external leakage of the medium.

A wide range of materials are available

The valve body, ball and sealing materials can be selected according to the characteristics of the medium, and are compatible with corrosive, high-purity or active media.

Diverse connection methods

We offer a variety of end connection forms such as flange, and welding, which are convenient for integration into various pipeline systems.
