The Corrosion Problem

Corrosion undermines the reliability of metal valves long before failure becomes visible. It restricts flow, weakens structural integrity, and leads to leaks that shut systems down without warning. This leads to constant maintenance, premature replacements, and rising operational risks drain both time and budget. The reality is simple, metal valves cannot withstand harsh environments. A better, corrosion proof alternative is now more essential than ever.

TYPE 23

3 Way Ball Valve

Multi Functional Handle

Removing the handle and placing the raised lugs into the carrier allows for easy disassembly of the valve. The handle also comes in different colours including blue, white, yellow and green.

Double-O-ring

The stem uses a double-O-ring, sealing arrangement improving durability sealing performance. The upper O-ring groove is deeper than the lower O-ring groove. Because of this design, if the stem were to break, it would do so first at the upper O-ring groove, acting as a back up seal.

Easy to Be Automated (no modification required)

AsahiAV Ball valves feature a new integral molded top flange. The valve can easily be converted from the manual to automatic without replacing the body.

Interchangeable with Ball Valve Type21

The face-to-face dimensions, as well as the connecting parts, end connectors and union nuts, are the same as the ball valve Type21.

Compact and Economic

The 3-way Ball Valve allows two flow patterns, using one valve. The valve is suitable for a pipeline which requires two ball valves and a tee. That is, the 3-way Ball Valve is economic because it makes piping compact and saves space.

Reversible Flow Direction

The 3-way Ball Valve is based on the Asahi true union ball valve design which can be installed or removed only by tightening or loosening its union nut.

Thermoplastic Advantages

Asahi valves are made from plastic materials such as unplasticized polyvinyl chloride (U-PVC), polypropylene (PP), and polyvinylidene fluoride (PVDF), providing numerous benefits such as superior corrosion and chemical resistance when compared to metal valves.

Corrosion Resistant

Our diverse range of plastic materials for our valves provides excellent resistance to corrosion and chemicals

Lightweight

ASAHI valves are much lighter when compared with typical metal valves being between 20% - 25% lighter

Low Maintenance

Due to their resistance to corrosion and scaling our valves require minimal maintenance

Long Lifespan

Our valves are designed for longevity, with excellent resistance to wear ensuring a long service life

Mechanically Strong

Despite their lightweight nature, thermoplastic valves are engineered to be mechanically robust and can withstand high pressures and mechanical stresses.

Theft-Resistant

Thermoplastic valves have little to no scrap value and are less attractive to thieves.

Benefits of AsahiAV Ball Valves

Choosing AsahiAV ball valves gives facilities the confidence to operate without the constant disruptions caused by corrosion and metal valve failures. Our valves improve reliability, reduce maintenance demands, and protecting systems from unexpected breakdowns, helping organisations run more efficiently and more cost effectively. The result is a smoother operation, a safer working environment, and long term performance that supports both productivity and profitability.

Greater System Uptime

Corrosion proof performance keeps valves operating reliably, which means fewer interruptions, fewer shutdowns, and more consistent production output.

Lower Maintenance and Operating Costs

With no rust related failures or emergency repairs to manage, maintenance becomes predictable and affordable. This reduces total lifecycle costs and frees up budget for other priorities.

Improved Operational Safety and Confidence

By removing the risk of leaks, contamination, and sudden valve failure, teams can operate with greater certainty and trust in their system’s long term stability.

Get Pricing Tailored to Your Application

Every system has unique operating conditions, and the real cost of a valve depends on how well it performs within those conditions. Asahi Africa offers fixed, transparent pricing on all ball valves, but the most cost effective outcome comes from selecting the correct material, size, and configuration for your application.

Our team will review your environment, media, temperature, and pressure requirements to guide you toward the option that delivers the lowest total cost of ownership. This ensures you receive a solution that performs reliably without paying for capabilities you do not need.

Wide Range of Ball Valves

Highly customisable with a range of elastomers and plastics to specify from.

FAQ's

Selecting the right valve for your system often raises important technical and operational considerations. To support your decision making, we have compiled a list of the questions we are most frequently asked by engineers, maintenance teams, and project managers. These FAQs are designed to give you clarity on performance, compatibility, installation, and long term value so you can choose with confidence.
Thermoplastic ball valves offer corrosion proof performance that metal valves cannot match. Unlike metal, thermoplastics do not rust, pit, or degrade when exposed to aggressive chemicals, chlorinated water, or harsh process conditions. This gives you longer service life and far fewer maintenance interventions. 

Thermoplastic valves are also lightweight, easier to install, and provide smoother internal surfaces that support stable flow and reduced pressure loss. The result is a reliable, cost effective alternative that performs consistently in environments where metal valves often fail.
Yes. AsahiAV ball valves are designed specifically for environments where chemical resistance is essential. Depending on your media and temperature requirements, materials such as PVC, CPVC, PVDF, or PP can be selected to ensure long term stability and performance in corrosive or aggressive conditions.
Material selection depends on the type of media, temperature, pressure, and environment within your system. Our specialists can review your operating conditions and recommend the ideal material for long term reliability.
Yes. AsahiAV ball valves are available in a wide range of sizes and connection types that match common piping standards. Options include socket, threaded, and flanged connections, allowing easy integration into existing systems.
Thermoplastic ball valves require far less maintenance because they do not corrode or degrade in the same way metal valves do. Routine checks are still recommended, but the overall maintenance burden is significantly lower.
Service life depends on a multitude of conditions, but AsahiAV valves demonstrate long term reliability in environments where metal valves typically fail early due to corrosion or chemical attack. When correctly selected, they offer a durable, predictable lifespan.
Thermoplastic valves can handle some solids, although performance varies based on particle size and concentration. In applications with heavy abrasion, material choice and valve design are important. Our team can assess your application and recommend the best option.
Yes. AsahiAV ball valves can be used manually or fitted with electric or pneumatic actuators for automated service. The valve design supports accurate control in automated systems.
