PYZQ2 Type High-Pressure Ball Valve

I. Product Introduction

High-pressure ball valves emerged in the 1950s. With technological advancement, manufacturing process upgrades, and product structure optimization over decades of industry development, they have become mainstream valve products for industrial pipelines. In developed industrial nations, the market application of high-pressure ball valves has been growing year by year. In China, the application coverage of high-pressure ball valves continues to expand, widely adaptable to petroleum refining, long-distance fluid pipelines, chemical processing, papermaking, pharmaceuticals, water conservancy, electric power, municipal engineering, and steel industries. They occupy an important position in industrial fluid control and national production supporting systems.

The basic functions of high-pressure ball valves are pipeline medium shut-off and conduction, while also accommodating fluid flow regulation and operational fluid control. The product category offers strong adaptability. Among them, hard-sealed V-type ball valves, featuring V-shaped ball cores paired with hard alloy overlay metal seats, provide excellent shearing force at the contact surface, suitable for conveying and controlling fiber-containing media and fine solid particle media. Multi-port high-pressure ball valves can flexibly control pipeline media merging, splitting, and flow direction switching, capable of independently closing any single channel while connecting the remaining two channels, meeting the requirements of multi-pipeline directional switching operations. These valves are conventionally adapted for horizontal pipeline installation, ensuring stable opening/closing and sealing performance.

III. Category Classification and Functions

1. Standard High-Pressure Ball Valve: Achieves pipeline medium on/off control and fluid flow regulation, suitable for conventional clean hydraulic and oil/gas media pipelines;

2. Hard-Sealed V-Type Ball Valve: High hardness ball core and seat with strong shearing force, suitable for media containing fibers and fine solid impurities, resistant to valve sticking, wear-resistant and durable;

3. Multi-Port High-Pressure Ball Valve: Capable of media splitting, merging, and flow direction switching, can independently close a single channel while connecting remaining pipelines, suitable for multi-pipeline integrated control systems.

IV. Product Features

1. Wide application adaptability, pressure-bearing performance suited for industrial high-pressure pipelines, adaptable to oil/gas, chemical, and water engineering multi-type media transport control;

2. Strong multi-functionality, a single valve can achieve on/off, regulation, and directional switching functions, reducing the number of valves required in multi-pipeline systems;

3. Hard-sealed models have strong impurity resistance, shearing and crushing media debris, suitable for complex media containing solids and fiber impurities;

4. Convenient opening/closing operation, flexible ball rotation, fast pipeline response, tight sealing, low leakage rate under high-pressure conditions;

5. Standardized structure design, stable operation with conventional horizontal installation, strong installation adaptability, easy maintenance and inspection.

V. Application Fields

Suitable for petroleum refining, long-distance media pipelines, fine chemical processing, papermaking and pharmaceuticals, water conservancy pump stations, power generation units, municipal pipeline networks, and steel metallurgy industries. Can be integrated with hydraulic energy storage systems and process transport pipelines for media shut-off, pressure regulation, and directional control applications.

VI. Usage Precautions

1. Prioritize horizontal installation, conforming to valve body structural stress standards, ensuring stable ball sealing and opening/closing performance;

2. For media containing solid and fiber impurities, prioritize V-type hard-sealed models to reduce valve core jamming and wear;

3. Verify pipeline nominal pressure and select ball valves with matching pressure ratings to avoid long-term overpressure operation;

4. Operate multi-port ball valve directional switching smoothly with slow opening/closing to avoid instantaneous water hammer or oil pressure surge;

5. Regularly clean valve chamber impurities, inspect sealing surface wear, and maintain valve body sealing and shearing performance.
