The robust device locks the valve handle at open or close position and allow to add a pad lock (up to 6mm) for misuse prevention. The spring-load construction ensure handle is lock
in position at all valve installation orientations and under vibrating conditions. An accidently push / pull / turn of the handle is prevented.

A spring-loaded device that force the valve into close or open base position, by manually forcing the valve handle it can be temporary turned into the opposite position (close or open respectively).
Once handle is released the device will automatic force the valve into its base position.

device internals are open to atmosphere (no pressure is build inside)

Fugitive Emission Bonnet (FE)

Pressure range:

Array ( [introduction_text] =>

An extension device to allow a larger distance between the handle or actuator and the valve body. The extension bonnet does not seal at its upper end and is open to the atmosphere.
The valve stem seal is in use for media sealing.

• Valve and pipe lines need to be insulated
• Valve operation must be elevated from extreme temperature areas
• Direct mounting of actuator to a valve is not suitable

Caution!: In any case the vents are sealed – pressure within the FE bonnet must not exceed 50 bar!

Extended Bonnet (EXT)

Size range

Pressure range:

Array ( [introduction_text] =>

In applications that use a fail-safe actuator, the spring chambers are exposed to the surrounding environment. Every stroke generated by the force of the springs introduces air from the
surroundings into the actuator’s inner parts. In the case of corrosive and/or abrasive working environments, the springs and the interior of the spring chamber become prone to damage
that could cause the product to malfunction.
The Breather Block isolates the actuator’s internal parts from the corrosive/abrasive surroundings by allowing only dry and filtered instrument air to flow into the spring chamber during the
actuator’s spring stroke. The Breather Block’s exhaust port only allows air to flow out of the spring chamber and prevents outside air from flowing in.

air supply tubes can be connected to the inlet port with a ¼” NPT (Imperial) or M5-10/24 UNC (Metric) connector

Breather Block

Size range

C15 up to C100

Pressure range:

Array ( [introduction_text] =>

In a failsafe actuator compressed air inside the actuator preloads the springs. During normal operation, each time the solenoid valve is tripped the compressed air is released into the
atmosphere through the solenoid valve’s exhaust port. The patented IMPACT™ unit diverts part of this energy to the spring chamber in order to boost the torque of the actuator by at least 50%.
The IMPACT™ also functions as a Breather Block that isolates the spring chamber from the atmosphere, and as a check valve that ensures that the temporary reduction of the compressed air pressure does not trigger movement of the valve and actuator to the mid-position. The IMPACT™ is used for on/off systems only, and cannot be used for control applications.
