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
This product consists of either a single or dual channel valve
configuration connected to a main air supply, optionally 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 high operational pressure is achieved. At a
defined pressure the soft start valve applies 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 1) The valve must be energised/de-energised at least once per week.
Note 2) If lubrication is used in the system, use class 1 turbine oil (no additive), ISO
VG32.
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 on
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 8.3 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.

Note 1) For the purposes of EN ISO 13849-2 table D.2 the switch is de-rated from
the figures specified by the switch manufacturer. The switch load must be
limited in the application in order to maintain the specified safety
performance, including the B and mission time.
