Link Mfg. has unveiled four all-makes 1500 Series height control valves that can be retrofitted to almost any truck and trailer air suspension system.

The valves all come with a universal mounting kit, and Link says they offer more flexibility in mounting, plumbing and lever attachments.

“Each kit contains all the necessary elbow connectors, quick-connect fittings and hardware to make installation a simple, less-than-15-minute exercise,” said Brian Kujala, vice-president — business development for Link Mfg.

The installation process is eased with push-to-connect fittings and supply port check valves. Metric fittings are also available.

Each valve’s alignment notch can also be rotated 180 degrees to get the proper fill-exhaust directions for the desired lever travel, the company adds.

Buyers don’t need to worry about OE reference part numbers, either.

“All we need to ask is: ‘Pressure applied to dump? And the answer is our H01501UD; Pressure removed? And the answer is our H01502UNC; Non dump or no dump feature? And the answer is our H01500; 1/4-inch fitting option? And the answer is our H01501PUD,” Kujala said.

Zero-pressure, pressure-dump and non-dump configurations are available, and the height control valves come in optional high- and low-flow versions.

“Link’s All Makes 1500 Series valves can be mounted inline or upright to the chassis with a 3/8-inch PTC fitting standard or an available 1/4-inch custom PTC fitting,” Kujala said.
