52331 Series
Description
The 52331 Air Suspension Leveling Valve (SRHLV) combines Barksdale's patented Shear Seal technology with a second ride height feature. This new product offers Shear Seal's industry leading durability with the ability to select two controlled ride settings at the flip of switch.
The SRHLV is engineered to customer specifications to either raise or lower vehicle air suspensions a specific distance at the end of the valve arm or number of degrees of shaft angle. The second ride height is activated by simply applying 75 PSI (5 bar) to the pilot port. Releasing pressure at the pilot port returns height control to the standard (default) setting.
Whether in second ride height or standard (default) ride height vehicle suspension control our proportional response design conserves on-board compressed air while maintaining precise
control.
