Dolly Control Line Valves are primarily used on dollies and turntable axles. Their ability to increase control line flow speeds brake application and release times dramatically. Modified dolly port helps offset timing inbalances in certain brake systems...
This valve is typically used to deflate air suspension ride bags when the trailer is parked. It exhausts the delivery line when the pilot pressure is released. Pressurizing the pilot allows supply to flow to the delivery port. NPT Port Size = 3/8'' All
Used as a park brake release valve outside on dollies & trailers. Inlet Port (NPT) = 1/4'' Outlet Port (NPT) = 1/4'' Exhaust Port (NPT) = 1/4''
These valves quickly exhaust delivery pressure when the supply line pressure to the inlet port drops. They are commonly used to release large air volumes from devices such as air suspension bags. Inlet Port (NPT) = 3/8'' Outlet Port (NPT) =...
