3/2-way quick exhaust safety valves
Series MD SAFEMAX
Series MD SAFEMAX solenoid valves are equipped with an integrated sensor that detects the position of the spool and enables to quickly exhaust the system in case of emergency.
The sensor is in ON status (LED switched on, electric contact closed) when the valve is in rest position (NC).
The single channel valve is classified in category 2 and can reach Performance level D.
The double channel valve is classified in category 4 and can reach Performance level E.
The user is responsible to perform the installation in compliance with the requirements of the ISO EN 13849-1 standard.
Please note: the safety valve is not sufficient, alone, to guarantee the safety function. Its setup requires the use of a monitoring device.
The Machinery Directive (MD) 2006/42 / EC establishes the safety requirements that a machine must respect in order to protect the health of people during its use.
Series MD SAFEMAX solenoid valves comply with ISO 13849-1, regarding the safe design of control systems that perform safety functions.
