Note)
Safety component as defined by the Machinery
Directive 2006/42/EC article 2c/ The Supply of
Machinery (safety) Regulations 2008 part 2.4(2)(c).
The intended use of this valve is to vent a protected system to
atmosphere when it is de-energised. When properly integrated into a
suitable safety system the duplex valves are compatible for use in
systems up to Category 4, and the single valves are compatible for use
in systems up to Category 2 as defined by EN ISO 13849-1.

2.1 Functional description
The product consists of either one or two solenoid operated 2 position 3
port valves, which are connected to a main air supply (in some cases via
an integrated soft-start valve). The valves are capable of performing the
safety function described in this document. The soft start valve is
intended to allow the end user to perform machine operational start up
procedures with reduced flow potential until a pre-set operational
pressure is achieved. At the defined pressure the soft start valve allows
full flow in order to achieve full operation. The soft start function is
intended for machine operation purposes and not for the performance of
a safety function.

Note 2) The valve must be energised/de-energised at least once per week.
Note 3) See section 2.5 for switch impact/vibration specifications.
Note 4) Impact resistance:
• No malfunction resulted from the impact test using a drop impact tester.
• The test was performed in both energised and de-energised states to
the axis of and at right angles to the direction of the main valve and
armature (Values quoted are for a new valve).
Note 5) Vibration resistance:
• No malfunction occurred in a one-sweep test between 5 and 2000 Hz.
• Test was performed in both energised and de-energised states to the
axis of and at right angles to the direction of the main valve and armature
(Values quoted are for a new valve).
Note 6) The B figure is estimated from SMC life tests under SMC test conditions.
