INTRODUCTION

In modern industrial piping systems, flow control components play a decisive role in ensuring operational safety, efficiency, and longevity of the process. Among these components, the Union Ball Valve has emerged as a highly preferred isolation valve due to its compact design, ease of maintenance, and reliable shut-off performance. Krishna Industries, based in Ahmedabad, Gujarat, India, supplies high-quality Union Ball Valves to Indian industries that demand durability, precision, and consistent performance under varied operating conditions.

A Union Ball Valve is a quarter-turn valve that uses a spherical ball with a central bore to control fluid flow. What differentiates it from a standard ball valve is the presence of union ends, which allow the valve to be easily removed from the pipeline without disturbing adjacent piping. This feature makes union type ball valves especially suitable for applications where frequent inspection, cleaning, or replacement is required.

In the Indian industrial landscape, Union Ball Valves are widely used across water treatment plants, chemical processing units, pharmaceutical manufacturing, food and beverage industries, irrigation systems, HVAC installations, and OEM machinery. These valves are valued for their leak-tight sealing, smooth operation, and compatibility with a wide range of fluids including water, air, oils, chemicals, and mild acids.

Krishna Industries supplies Union Ball Valves that are engineered to meet Indian operating conditions, pressure requirements, and installation practices. Our product range is designed keeping in mind the needs of Indian buyers who prioritize quality, availability, technical support, and long-term reliability. As a supplier located in Ahmedabad, Gujarat, we ensure timely delivery across India and offer technical guidance to help customers select the right valve for their application.

This product page provides a comprehensive overview of Union Ball Valves, including design features, working principle, materials, specifications, applications, advantages, installation guidelines, and frequently asked questions. It is intended to serve as a complete reference for engineers, procurement managers, maintenance teams, and project consultants looking for a dependable Union Ball Valve supplier in India.

WHAT IS A UNION BALL VALVE

A Union Ball Valve is a type of ball valve that incorporates union connections on one or both sides of the valve body. A union connection consists of a nut that allows easy disassembly of the valve from the pipeline. This design eliminates the need to cut pipes or dismantle large sections of piping during maintenance or replacement.

The valve operates on a quarter-turn mechanism. When the handle is aligned parallel to the pipeline, the valve is open and allows full flow. When the handle is rotated 90 degrees, the ball rotates and blocks the flow completely, providing tight shut-off.

Union Ball Valves are available in various sizes, pressure ratings, and materials, making them suitable for a wide range of industrial and commercial applications in India.

DESIGN AND CONSTRUCTION

Union Ball Valves supplied by Krishna Industries are designed with precision and robustness. The typical construction includes:

Valve Body
The body is manufactured from materials such as UPVC, CPVC, PP, or metal depending on the application. For most Indian water and chemical applications, UPVC union ball valves are widely preferred due to their corrosion resistance and cost-effectiveness.

Ball
The ball is precision-machined to ensure smooth rotation and tight sealing. It is usually made from the same material as the body or stainless steel in higher-end designs.

Seats
Seats are made from PTFE or other suitable sealing materials to provide leak-proof performance even after repeated operation.

Union Nuts
Union nuts allow easy dismantling of the valve from the pipeline. This feature significantly reduces maintenance downtime.

Stem and Handle
The stem is designed for smooth torque transmission, while the handle provides clear open/close indication and easy manual operation.

WORKING PRINCIPLE

The working principle of a Union Ball Valve is simple and highly efficient. The valve uses a spherical ball with a through-hole aligned with the pipeline. When the valve handle is turned 90 degrees, the ball rotates and either allows or blocks the flow.

Because of the full-bore design, pressure drop across the valve is minimal. This makes union ball valves suitable for applications where flow efficiency is critical.

The union ends allow the valve body to be removed without rotating the entire valve or disturbing the pipeline alignment, which is especially beneficial in compact installations.

MATERIAL OPTIONS

Krishna Industries supplies Union Ball Valves in multiple material options to suit Indian industrial requirements:

UPVC Union Ball Valve
Widely used for water treatment, irrigation, and chemical handling due to excellent corrosion resistance.

CPVC Union Ball Valve
Suitable for higher temperature applications compared to UPVC.

PP Union Ball Valve
Used in specific chemical applications where compatibility is required.

Metal Union Ball Valve
Available on request for high-pressure or specialized industrial applications.

SIZE RANGE AND PRESSURE RATINGS

Union Ball Valves are available in various sizes typically ranging from 15 NB to 100 NB for plastic valves. Pressure ratings generally conform to PN10 or PN16 standards depending on material and design.

Krishna Industries ensures that all supplied valves meet standard Indian operating conditions and are suitable for long-term service.
