The ROSS Pneumatrol E238L0 Series is a low pressure 3/2 pilot-operated pneumatic solenoid valve engineered for applications where standard pilot-operated valves require higher operating pressures than are available within the system. Designed with an external pilot arrangement and spring return operation, the E238L0 provides dependable pneumatic control from pressures as low as 1.5 bar.
Featuring a remote-mounted design and compatibility with a wide range of safe area and hazardous area solenoid operators, the E238L0 offers a flexible solution for low-pressure pneumatic control systems across industrial automation, process control and valve actuation applications.
