Steel Ball Valves
The Vexve steel ball valve (type NAVAL) reliably opens and shuts off the flow of liquids in piping systems
and is characterized in particular by very good flow rates, absolute tightness, easy handling and high resistance to wear and corrosion.
and is characterized in particular by very good flow rates, absolute tightness, easy handling and high resistance to wear and corrosion.
Depending on requirements, we offer steel ball valves in various designs:
In the standard design, the stainless steel ball is floating and has spring-loaded seals.
This variant is suitable for many different applications and is reliable, durable and cost-effective.
For particularly demanding and critical conditions, as well as for larger ball diameters
we recommend our trunnion-mounted steel ball valves with a fixed stainless steel ball and floating sealing rings.
In combination with many other features, such as the double block & bleed function and the single-piston effect,
this variant offers even greater stability and safety.
Vexve steel ball valves can be used in a variety of process control applications, such as heating and cooling systems,
and are particularly suitable for district heating and cooling water, oil and compressed air.
