Double Shut-off Hansen Couplings – sometimes referred to as Two-way shut-off or Hydraulic Couplings

Double shut-off Hansen couplings have a check valve in both the socket and plug. These quick disconnect couplings are used in systems where down stream spillage is undesirable.  Hansen Double shut-off couplings are commonly associated with use in hydraulic systems. However, many different applications exist for this type of quick coupling. They are found on systems handling steam, solvents, cooling water, oil, and a host of other media.

Double shut-off Hansen couplings are normally capable of much higher pressures then single shut-off couplings. Working pressures of up to 10,000 PSI are common. Some special hydraulic coupling designs can reach 20,000 PSI, all depending upon design and material.

Double shut-off coupling designs are quite versatile, allowing them to be converted to single shut-off designs or straight-through designs.

Double shut-off Hansen couplings are also available in a wide range of materials. The most common being steel, brass and stainless steel
