Dual-Safe (DB&B) valve

The Habonim Dual-Safe valve series presents an optimal design solution and guarantees isolation on critical applications and service when an emergency shut-down (ESD) valve is a necessity.
The Dual-Safe unit incorporates two main isolation valves and one bleed valve in a single body construction.
This special construction offers the lowest possible number of potential leakage points from a process connection and reduces the overall valve envelope size and weight by integrating valves, piping, and fittings into one compact design.

Dual-Safe features
■ Minimizes the risk of furnace explosion.
■ Increases system reliability.
■ Saves space and reduces weight.
■ Reduces installation time.
■ Streamlines maintenance operations.
■ Reduces number of items in repair kits.
■ Rugged construction.
■ Bubble tight shutoff on all three valves.
■ Coupled operating mechanism reduces the number of actuators on the main line
■ Tongue and groove design for all body seals Variety of end connections (welded, threaded, flanged)
