Brass Threaded Ball Valves
A brass threaded ball valve is a ball valve whose body is forged or machined from brass alloy and screwed directly onto the pipe thread. It is the most common shut-off valve in installations and the first choice on most water and compressed air lines.
The range extends from 1/8″ mini valves to 4″ industrial valves. Lever or butterfly handle options, female–female and female–male types, natural gas types and models with integrated check valves are grouped under the same heading.
Main Applications
- Hot and cold water distribution in residential and commercial buildings
- Shut-off points upstream of meters and at apartment entries
- Compressed air installations and compressor lines
- Suction and discharge connections of pump and booster sets
- Garden irrigation and manifold outlets
- Natural gas indoor installations with suitable approved models

The PN25 column is taken from the manufacturer datasheet of a brass valve designed for water and air lines. On PN16, PN40 and natural gas models the ball, stem and seal materials vary by manufacturer and are stated with the product datasheet in the quotation.
Advantages
Economical Solution
- It is the lowest cost shut-off valve on small bores.
- This group offers the widest choice of sizes in stock.
Compact Body
- A DN15 valve is only 43.5 mm long.
- It fits the tight spaces between meters and manifolds.
Light
- A DN15 valve weighs about 0.14 kg.
- It needs no extra hangers or supports.
Handle Choice
- A butterfly handle turns easily in tight spaces.
- A long lever gives a torque advantage on larger sizes.
Construction and Design Features
- Body and end connections are machined or forged from a single brass block.
- The ball sits in a floating position between two seat rings.
- The thread profile is cut to EN ISO 228-1; sealing is made with paste or tape on the thread.
- The handle is fixed to the stem with a nut and sits perpendicular to the pipe when closed.
- On butterfly handle types the handle is kept short to ease turning in tight spaces.

How to Choose?
- Confirm the mediumChoose the standard type for water and air, and an approved natural gas model for gas lines.
- Check the temperature limitThe water-air type is not used above 80 °C; look at stainless models for hot lines.
- Define the pressure classPN16 suits building lines; PN25 and PN40 suit pump discharges and industrial lines.
- Match the thread typeSelect female–female or female–male according to the pipe and fitting to be connected.
- Decide on the handlePrefer a butterfly handle in tight spots such as wall corners and manifolds.
