|
 |
- A pneumatic, double piloted, three way valve that changes the air passages through it when air pressure of a predetermined amount or more is in the control chamber
- Used in various ways including to control a large flow of air piloted by a small amount of control air, an interlock to control flow of air in one circuit by placing its control in another independent air circuit, as a sequence valve for timing, cycling, etc.
- Not interchangeable with an HB Relay Air Valve
|
 |
- Efficient, cost effective, maintenance-free way to precipitate moisture from compressed air braking systems
- Reduces the need for cooling piping or tubing between the discharge and the first main reservoir
|
 |
Receives a signal from the control valve or independent brake valve to allow main reservoir air to the brake cylinders to provide a brake application.
