Sanitary Ball Valves
Dead-space-free ball valves for hygienic applications. Patented seal technology reduces cleaning time by 40%.
Dead-space-free
Patented seal technology eliminates dead legs where bacteria can grow.
40% faster cleaning
Dead-space-free design reduces CIP time and cleaning chemical consumption.
CIP/SIP compatible
Designed for clean-in-place and sterilize-in-place procedures.
Easy maintenance
Few high-quality parts make maintenance and seal replacement fast.

What is dead-space-free?
In conventional ball valves, small gaps exist between the ball and the seals, creating "dead spaces" where product can accumulate and bacteria can grow. These areas are difficult to clean and can contaminate subsequent batches.
Trinox / Gulbinat's patented seal technology eliminates these dead spaces. The specially designed seals maintain continuous contact with the ball surface throughout its rotation, leaving no gaps where product can collect.
The result is a valve that's nearly 100% cleanable, reducing CIP times by up to 40% and virtually eliminating cross-contamination risk between batches.
How it works
The Trinox / Gulbinat ball valve uses a floating ball design with specially profiled PTFE seals. When the valve is pressurized, the seals are pushed against the ball with uniform force.
As the ball rotates, the seal profile maintains continuous contact, so there's never a gap between the seal and ball surface where product can accumulate.
Key design features:
- Floating ball design
- Profiled PTFE seals
- Uniform seal loading
- Continuous ball contact
- Self-draining body
