ROSS Controls 1523B4002 Relief Valve

ROSS Controls 1523B4002 Relief Valve is a compact pneumatic pressure‑relief device designed to vent excess pressure when the set point is exceeded, protecting upstream components from overpressure. It features 3/8‑inch NPT threaded ports for straightforward installation into standard pneumatic lines and can be used in conjunction with Ross Controls’ 15 Series lockout valves to form compact safety assemblies in maintenance workflows. This relief valve provides a controlled vent path, helping to prevent actuator overload, line damage, and unintended actuation in compressed air systems. Typical applications include protection of manifolds and pneumatic actuators in industrial circuits where space is at a premium and where safety interlock hardware is employed, allowing engineers to couple energy‑isolation with relief capabilities in a single compact package. When paired with compatible Ross Controls hardware, the 1523B4002 supports integration into small‑footprint control and safety solutions, enabling reliable venting during fault conditions without requiring large or complex plumbing.
