Valves series A1N - Flameproof coil Ex db

1/4”, 3/2 - 5/2, NAMUR interface, electrically operated Ex db

Series of spool valves, with static seals, high flow, for mounting on NAMUR
interface

Flameproof solenoid operator is used extensively to prevent possible
overheating or sparking of electrical equipment causing ignition in potentially
explosive atmosphere.

Flameproof solenoid coil is enclused in a robust enclosure which will contain
an internal explosion should it occur and prevent its transmission to the
surrounding atmosphere.

All construction joints in the enclosure are known as flame paths which prevent
the transmission of a flame from the enclosure to the outside atmosphere.

Speed controllers for double acting (APNRDA type) and spring
return (APNRSR type) pneumatic actuators, to mount directly
on the actuator or using with NAMUR solenoid valves and/or
positioners.
These speed regulators was designed with an advanced throttling
technology that was specifically made for the use of controlling the
opening and closing speeds of pneumatic actuators.
The speed controller is able to control the rotary speed of the
actuator at any rate accurately, consistently and safely without
the fluctuation that is commonly found in the standard speed
controllers.
