Brass ball valves for low and medium pressure are used for opening and closing compressed air, water and city gas. Available in standard series, these ball valves come in a wide range of models: in-line, lockable or venting, short or long thread. Working pressure: up to 40 bar and working temperature: -50°C to +170°C according to the model.
Legris stainless steel ball valves are suitable for aggressive fluids and corrosive environments. They provide excellent resistance to pressure (up to 64 bar nominal) and temperature up to 150° C.
Legris is also offering Ball Valves for High Pressure and Oxygen lines.
Ball Valves, degreased/Oxygen-compatible grease are offered for Oxygen service.
This range of ball valves is suitable for many industrial applications, when the fluid carried and working temperatures require PTFE seals.
The range is available in following versions.
Models 4902
1. Excellent resistance to high pressure and temperature constraints.
2. Full flow fluid passage.
3. Silicone free in order to meet specific application requirements -e.g. automotive process industry.
4. Both high quality and good value.
Fluids: compressed air,gas,waterstream,oil and all fluids suitable with constituent materials.
Working temperature: -20 ℃ to +130 ℃
Working pressure: 25 to 30 bar, depending on the model.
body: sand blasted nickel-plated brass

Ball Valves are by definition shut-off valves that open and close. The flow rate is varied by the rotation of an open ball. Our 4913 Series Chrome Plated brass ball valve is a unique designed valve which can be used in water application for Plumbing, Oil, Air, Fire Fighting & Water circulation systems. Many choices in sizes, optimum sealing, excellent resistance to scaling, smooth operation due to low friction coefficient of chemically chrome-plated brass, excellent resistance to pressure and temperature constrains. Theoretically, volumetric flows could be controlled with a ball valve instead of a globe valve. Using a ball valve would even be cheaper.

High Pressure Ball Valves are offered with a design pressure upto 500 Bar.
Legris high pressure ball valves are suited for a wide range of industrial applications. They are designed both for mobile applications (agricultural machinery, public works equipment, etc,) and stationary applications (offshore platforms,defence,ship building, paper industry,etc,)
Legris offers a range of valves which meets many customer requirements.
This type of ball valve operates according to the floating ball principal. In the closed position,pressure the floating ball against the seal,for full sealing.
The seal also acts as a guide.
Two-way ball valves must only be used in the open or closed position.
Use in an intermediate position, for controlling flow should be avoided.
Parker 7321B/7322B are diaphragm pilot operated solenoid valves and require a minimum differential pressure to operate. This series is available in both Normally Closed and Normally Open function:7321B Series is a Normally Closed family(closed when de-energised), 7322B Series is the Normally Open family(Open when de-energised).
Best performances for minimum and maximum operating pressure differential
Exclusive diaphragm design for a Superior Flow Rate, higher than the competition valves with the same dimensional specs and flat diaphragm
One of the Fastest in electrical and hydraulic opening response time
Modular concept: a wide rang of electrical parts increases the versatility of this product
