Dual Monitored Valves
"Safety Package Systems" ( Suit Category 3
& 4 )
- 'Safety package
systems' are
dual monitored valve systems, which comprise of
2 monitored valves mounted on 1 series ported
manifold for pneumatic safety
applications.
- Used to interface fluid power
operation of plant with electrical safety
circuits, 'Safety package systems' prevent
single faults, within fluid power safety
systems, from leading to the loss of the safety
function.
- Correct monitoring ensures
single fault detection and prevents further
operation of the secondary valve until the fault
is corrected.
- Once correctly connected to an
approved device (an approved, dual channel
safety relay) for monitoring of the dual
redundancy, the 'Safety package systems'
are:
- Dual redundant in function
- Monitored for a fault
and, therefore, the loss of dual redundancy.
- Of fail-to-safe design (a single fault does
not lead to the loss of the safety function).
- Able to lock-out and inhibit further operation upon detection of a fault until corrected.
- 'Safety package
systems'
are available in a variety of port sizes, flow
rates and spool configurations (depending on the
application). This signifies that the versatile
range is capable of safely controlling and
isolating pneumatic power, whilst fulfilling the
widest range of needs in pneumatic energy
control.
- Our 'Safety package
systems' comply with all applicable directives (EC Machinery Directive 98/37/EC) and harmonized standards (EN 292-1, EN 292-2, EN 1050, EN 60204, EN 954.1, EN 983) for pneumatic fluid power systems and their components. They qualify for CE compliance and for use with Category 4 of control system in accordance with AS 4024 and EN 954.1.
