Bellows Sealed Construction

Metal bellows provide a complete seal between the fluid medium and atmosphere, ensuring zero leakage across all operating conditions.

Lift Check Design

Lift check mechanism ensures reliable non-return flow control, preventing backflow in process and industrial pipeline systems.

DIN Standard

Built to DIN standard for compatibility with European and international pipeline systems and process plant specifications.

Zero Stem Leakage

Bellows construction eliminates stem leakage, making this valve ideal for applications where fugitive emissions must be controlled.

Corrosion Resistant

Bellows material and construction selected for long service life in corrosive chemical and process media.

Wide Application Range

Suitable for process plants, chemical, pharmaceutical, power generation and industrial applications requiring reliable non-return valve performance.
