Trusted Engineering Expertise Behind Hirata Valves
Hirata Valve Industry exemplifies Japanese craftsmanship and reliability. With the Vacuum Safety Valve DN100 - Hirata Valve Industry, you're not only installing a product—you’re investing in long-term safety and operational continuity.

Integrated Safety in Piping Systems
In practical applications, vacuum safety valves are part of a comprehensive pipeline safety configuration. As illustrated in typical steam systems, the safety valve complements components like stop valves and pressure reducing valves to ensure a stable and secure process. Positioned downstream of critical pressure control devices, the vacuum safety valve plays a key role in maintaining pressure balance and preventing backflow or vacuum-induced collapse.
Systems that include Hirata’s DN100 vacuum safety valve benefit from enhanced operational reliability, particularly in setups where pressure fluctuations can impact sensitive steam-using equipment.
Protect Your Process — Choose Precision
When safety is non-negotiable, the Vacuum Safety Valve DN100 - Hirata Valve Industry delivers unmatched protection. Ensure your systems are shielded from costly damage caused by vacuum events.
