Discover our range of valves

Valves are mechanical devices that control, and more specifically open, close or regulate the flow of a liquid or gaseous medium in a pipeline. There are many different types of valves including: ball valves, needle valves, diaphragm valves, rotary lever valves, angle seat valves, flap valves and many others...

Valves are used for specific purposes: shut-off valves, control valves, bleed valves, etc. They can be found in almost all sectors of activity: industrial, plumbing, food, pharmaceutical, transport, medical, construction, automotive, but also in private households.

The shape of the valve body can be straight (inlet opposite the outlet), angled (inlet perpendicular to the outlet), bypass (one inlet, several outlets), mixer (two inlets, one outlet)...

The main characteristics of a valve :
  • - The type: ball, ball with padlockable lever, needle, diaphragm, rotary lever, angle seat, poppet...
  • - Thread (BSP, NPT) and nominal diameter (DN) 
  • - Compatible fluid(s): compressed air, water, oil, aggressive fluids...
  • - Material: nickel-plated brass, chrome-plated brass, stainless steel, technopolymer, etc.
  • - Nominal (PN) and maximum pressure
  • - Standard: DIN, ISO, ANSI, etc.
  • - Valve actuation: lever shape

 

Ball valves

This is the most common type of valve. They are valves equipped with a drilled ball. Its main advantage is its very good ergonomics, the lever (handle or butterfly) is indeed very easy and quick to operate (a quarter turn is enough to open or close the fluid passage). In addition, these valves are very compact and the tightness is guaranteed.

 

Compact ball valves

Materials and components
The compact ball valves are made of chrome-plated brass.

Field of application: compressed air, oil, water

  • - Maximum working pressure: -0,99 ÷ 20 BAR
  • - Working temperature: -20°C / +80°C
  • - Direction of fluid flow: both directions.

Mini series ball valves

The "mini series" ball valves are machined either :
- in chrome-plated hexagonal bar
- in forged, sandblasted or chrome-plated brass

Field of application: compressed air, oil, water

  • - Maximum working pressure: 10 BAR at 90°C
  • - Working temperature: -10°C / +90°C
  • - Direction of fluid flow: both directions.

Needle valves

Needle valves are manually operated valves and are particularly appreciated for their small size and low cost.

The most common application is the control of fluids (liquids or gases) at low flow rates and low pressures.

The valve is actuated by a small knob which allows the flow to be regulated.

 

Needle valves

Materials and components
- nickel-plated brass body
- resin knob
- NBR oil resistant rubber seals

Field of application: compressed air, water
- maximum working pressure: 18 BAR
- working temperature: -10°C / + 80°C
