Water and gas ball valves
Industrial bronze alloy ball valves up to 32 bar, mini ball valves, mini motorized valves and butterfly valves.
Valve selection on water, air and gas lines looks simple, but the wrong pressure rating or the wrong material means leaks and corrosion in the installation. We select the valve to suit the fluid, pressure and connection of the line and, where automation is needed, guide the move to a motorized or actuated type. We ship water and gas valves from stock across Türkiye and abroad, and also sell them through hidroticaret.com, our online store (Turkish).
Types
Industrial ball valves
Bronze alloy, up to 32 bar; on/off duty on water, air and gas lines.
Mini motorized valves
Opens and closes the valve by motor on small lines; automation where compressed air is not available.
Butterfly valves
Light and economical on/off duty on large diameter water and air lines; lever or gear operated.
Mini ball valves
For small lines and connections on devices and machines; male-female and female-female types.

How to select
The valve size is selected to match the nominal size of the line. In piping, size is sometimes given as DN (millimeters) and sometimes in inches; the table below gives the equivalents.
Material is selected according to the fluid: brass and bronze are common for water and air; drinking water requires a suitable alloy, and food and chemicals require stainless steel. On gas lines a valve approved for gas is used.
The pressure rating is marked on the valve (PN). The maximum line pressure and any pressure surge must stay below this value.
DN to inch conversion
| Nominal size (DN) | Inch |
|---|---|
| DN8 | 1/4" |
| DN10 | 3/8" |
| DN15 | 1/2" |
| DN20 | 3/4" |
| DN25 | 1" |
| DN32 | 1 1/4" |
| DN40 | 1 1/2" |
| DN50 | 2" |
| DN65 | 2 1/2" |
| DN80 | 3" |
| DN100 | 4" |
DN denotes the approximate bore of the pipe in millimeters; inch designation is used for threaded connections.
Frequently asked questions
What does PN on a valve mean?
It is the nominal pressure of the valve in bar; a PN16 valve is made for 16 bar.
Can a brass valve be used on a gas line?
Only those approved and marked for gas. An unapproved valve must not be used on a gas line.
Ball valve or butterfly valve?
A ball valve is more economical in small and medium sizes, a butterfly valve on large diameter water and air lines.
Can we automate an existing valve?
In small sizes the valve is replaced with a mini motorized valve; in large sizes it is replaced with an actuated type or an actuator is mounted on it.
What is DN15 in inches?
It is 1/2 inch. The table gives the equivalents for the other sizes.
