Flexible solution for complex flow control
MULTI-WAY BALL VALVE TYPE MW

The multi-way ball valve type MW is available in 3-way ball valve, 4-way ball valve, and 5-way ball valve configurations with T- or L-port ball designs. Additionally, custom variants with double-L ball, piggable passages, and other tailored configurations are available.

The 3-way ball valve type MW features a fully spring-loaded, dead space-free ball sealing system, making it ideal for media that crystallize, polymerize, or harden in dead spaces between the ball and housing, preventing operational issues.

Advantages

ATEC Multi-way Ball Valve Type_MW

image

Cavity free

The usual cavity between ball and housing in non- cavity free ball valves give cause for disturbance because residual products can crystallize, polymerize and so affect the function.

› Clean, non- false product

› No sediments of expensive products in the ball valve housing

image

Spring loaded ball sealing system

Approximately same torque at different temperatures This request can only be achieved by ball valves with a spring-loaded sealing system. Different heat expansion of metallic and synthetic material cause high torques by non spring-loaded sealing systems so that the valve can block and does not open or close anymore. Longer lifetime through spring- loaded sealing system. Spring-loaded cavity free ball valves achieve this improvement in a variety of processes. At abrasion, the spring-loaded sealing system guarantees a controlled compression of the ball sealing so that longer sealing life and leak-tightness can be realized

› Longer Lifetime

› Same torque at different temperatures

image

All sides sealed

All sides of the ball valve are spring loaded sealed.

› All sides tight – independent product inlet

Our type selection

Multi-way ball valves from ATEC are characterized by all-round sealing and a blowout-proof control shaft. Available as T- or L-drilling.
