Safety Valves

The 5/2-way safety valve consists of two mechanically separated pilot control systems and main valve systems. The valves are pneumatically operated and the dynamic self-monitoring system does not require additional electrical monitoring. With the appropriate application, performance level "e" (cat. 4) of DIN EN ISO 13849-1 is achieved. Excellent B10 values represent extremely long service life until the necessary replacement (T10d-value) of the valves.

The standard Herion two-hand start unit can be fitted to any machine function where the requirement exists for the operator to utilise both hands in order to begin operation. Both buttons need to be operated within 0.5 seconds in order to achieve an output. The unit is supplied as a strong, sealed unit designed to prevent accidental operation.
