2 inch ball valve prices can vary significantly depending on body material, connection type, pressure class, full bore or reduced bore design, application and manufacturing standard. Therefore, instead of asking only “How much is a 2 inch ball valve?”, the technical requirements of the installation should also be evaluated.
A 2 inch size generally corresponds to DN50 nominal diameter in the valve industry. DN50 ball valves are widely used in water systems, natural gas lines, industrial plants, pump systems, compressed air networks and process applications.
In this article, VANEX VALVE explains the factors affecting 2 inch ball valve prices, DN50 valve types, correct product selection and 2026 market price levels.
What Is a 2 Inch Ball Valve?
A 2 inch ball valve is a valve that controls liquid or gas flow through a pipeline using a perforated spherical closing element.
The valve is generally opened or closed by turning the handle 90 degrees.
2 inch ball valves may be used in:
Water systems
Industrial facilities
Natural gas lines
Compressed air systems
Fire protection systems
Pump and booster systems
Heating and cooling installations
Irrigation systems
Machinery installations
Chemical and process lines
The fluid type, working temperature and system pressure should always be considered when selecting the valve.
How Much Does a 2 Inch Ball Valve Cost?
There is no single price for 2 inch ball valves. Even two DN50 valves can have significantly different prices depending on material, pressure rating and connection type.
In July 2026 online market examples, retail prices for 2 inch brass ball valves were seen at approximately TRY 2,080–2,190, while 2 inch full bore natural gas ball valves were listed around TRY 2,716–2,800.
For DN50 flanged industrial ball valves, prices also vary according to pressure class. Market examples included approximately TRY 2,688 for DN50 PN6 and TRY 3,660 for DN50 PN16 models.
Stainless steel valves are generally more expensive. DN50 two-piece flanged 304 stainless steel ball valves have been seen around TRY 7,113, while three-piece DN50 304 stainless steel versions have been listed at approximately TRY 9,274.
These figures are market examples and are not VANEX VALVE sales prices. Prices may vary depending on exchange rates, raw material costs, standards, order quantity and project requirements.
Example 2026 Price Segments
2 Inch / DN50 Valve Type Approximate Market Level
Brass threaded ball valve TRY 2,080 and above
Natural gas ball valve TRY 2,700 and above
DN50 PN6 flanged ball valve Around TRY 2,688
DN50 PN10/16 flanged ball valve TRY 3,000–3,660
DN50 304 stainless flanged valve TRY 7,000 and above
DN50 three-piece 304 stainless valve TRY 9,000 and above

Factors Affecting 2 Inch Ball Valve Prices
1. Body Material
One of the most important price factors is the valve body material.
Brass Ball Valve
Brass ball valves are widely used in:
Water systems
Heating systems
Compressed air
Irrigation
Building mechanical installations
Their threaded connection makes installation practical.
Cast Iron / Ductile Iron Ball Valve
Cast iron or ductile iron ball valves may be preferred in industrial applications requiring flanged connections.
Common options include:
DN50 – PN10 – PN16
Stainless Steel Ball Valve
Stainless steel ball valves are preferred for more demanding operating conditions such as:
Chemical plants
Food processing
Industrial production lines
Corrosive fluids
Hygienic applications
Certain high-temperature applications
304 and 316 stainless steel grades are common choices.
2. Connection Type
Threaded Ball Valve
Threaded ball valves are widely used in small and medium-sized piping systems.
Advantages include:
Compact design
Easy installation
Low space requirement
Easy maintenance
Economical solution
Flanged Ball Valve
Flanged ball valves are widely preferred in industrial facilities.
DN50 flanged ball valves may be available in:
PN6 – PN10 – PN16 – PN25 – PN40
Higher pressure ratings may require stronger body and flange designs, affecting product cost.
3. Full Bore or Reduced Bore Design
A full bore ball valve has an internal flow passage close to the nominal pipe diameter when fully open.
Main advantages include:
Lower pressure drop
High flow capacity
Reduced turbulence
Better pump system efficiency
Improved process flow performance
4. Pressure Class
2 inch ball valves may be manufactured in different nominal pressure classes:
PN6 – PN10 – PN16 – PN25 – PN40
Selection should also consider fluid temperature, body material, seat material and the manufacturer's pressure-temperature limits.
5. Is a Natural Gas Ball Valve the Same as a Water Valve?
No.
Not every 2 inch ball valve is suitable for natural gas applications.
A natural gas valve should:
Be suitable for the gas being used
Meet applicable technical standards
Provide adequate leak-tightness
Use suitable sealing and body materials
A standard water valve should not be used in a gas line merely because its size is 2 inches.
How Many DN Is 2 Inches?
In the valve industry:
2 inches ≈ DN50 nominal size
You may therefore see terms such as:
2 inch ball valve
2" ball valve
DN50 ball valve
DN50 ball valve price
2 inch flanged ball valve
What Is a DN50 PN16 Ball Valve?
A DN50 PN16 ball valve is a ball valve with DN50 nominal diameter and PN16 nominal pressure classification.
It may be used in:
Industrial water lines
Mechanical installations
Pump systems
HVAC systems
Pressurized systems
Manufacturing plants
What Should You Consider When Buying a 2 Inch Ball Valve?
Before comparing prices, determine:
Fluid: Water / Air / Gas / Oil / Chemicals
Pressure: PN16 / PN25 / PN40 etc.
Temperature: Operating temperature
Connection: Threaded / Flanged / Welded
Bore: Full bore / Reduced bore
Material: Brass / Cast iron / Ductile iron / Carbon steel / Stainless steel
Quantity: Required order quantity
Is the Cheapest 2 Inch Ball Valve Always the Best Choice?
No.
An unsuitable low-cost valve may lead to:
Leakage
Pressure loss
Sealing problems
Premature seat wear
Handle mechanism failures
Production downtime
Additional maintenance costs
Therefore, reliability, service life and compatibility with the installation should also be evaluated.

Frequently Asked Questions
What DN is a 2 inch ball valve?
A 2 inch ball valve generally corresponds to DN50.
How much does a 2 inch ball valve cost?
In 2026 market examples, standard brass, gas and flanged valves were commonly found in the TRY 2,000–4,000 range, while stainless steel industrial valves were around TRY 7,000–9,000 and above.
What is a full bore 2 inch ball valve?
A full bore ball valve maintains a flow passage close to the nominal pipe diameter, helping reduce flow resistance and pressure loss.
Where is a DN50 ball valve used?
It may be used in water systems, mechanical installations, industrial processes, compressed air, pump systems and, when properly certified, gas systems.
Conclusion
2 inch ball valve prices are determined by more than diameter alone.
Correct selection should consider:
DN50 size + pressure class + connection type + material + fluid + working temperature
