The Habonim Dual-Safe Valve series, also called Double Block & Bleed valves presents an optimal design solution and guarantees isolation on critical applications and service when an emergency shut-down (ESD) vale 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.
Habonim’s Double Block & Bleed (DBB) valves are available as ball valves, or needle valves.
