With a fully automated system based on proven double disc gate valve technology, this solution ensures high operational efficiency while reducing maintenance and energy costs.

• Compact valve body: Smaller face-to-face dimensions and reduced weight for easier integration into space-constrained setups.
• Double block and purge: Two independent discs ensure true double block and purge, maximising sealing integrity and safety.
• Low steam consumption: Designed for energy savings, with minimal steam use for better environmental and cost performance.
• Corrosion & wear resistant: Hard-faced seats protect against wear, ensuring long-lasting performance even in harsh conditions.
• Simplified maintenance: Easy inspection access and minimal spare parts requirements reduce downtime and keep maintenance costs low.
