EXPLOSION PROOF PRESSURE RELIEF PROPORTIONAL VALVES 
81315

 

The explosion-proof pressure relief proportional valves are in compliance with ATEX 94/9/EC standards and are suitable for the use in potentially explosive atmospheres, that fall within the ATEX II 2GD either for gas or for dust classification.  The statement of conformity to the up mentioned standards is always supplied with the valve.  Upon request, PRE(D)*KD2valves can be supplied with a finishing surface treatment (zinc-nickel) suitable to ensure a salt spray resistance up to 600 h (test operated according to UNI EN ISO 9227 standards and test evaluation operated according to UNI EN ISO 10289 standards).  Pressure can be modulated continuously in proportion to the current supplied to the solenoid.  These valves can be controlled directly by a current control supply unit or by means of the relevant electronic control units to exploit valve performance to the full.

EX-PROOF PRESSURE REDUCING PROPORTIONAL VALVES
81515

ZDE3KD2 valves are direct operated pressure reducing proportional valves with ISO 4401-03 (CETOP RP121H) mounting surface. They are in compliance with ATEX 94/9/EC standards and are suitable for the use in potentially explosive atmospheres, that fall within the ATEX II 2GD either for gas or for dust classification.  The valves are used to reduce pressure in the secondary circuit branches thus ensuring stability of controlled pressure in the event of variations of the flow rate through the valve.  With the valves the statement of conformity to the upmentioned standards is always supplied.  The ZDE3KD2 valves are supplied with a finishing surface treatment (zinc-nickel) suitable to ensure a salt spray resistance up to 600 h (test operated according to UNI EN ISO 9227 standards and test evaluation operated according to UNI EN ISO 10289 standards).

The DZCE*KD2are explosion-proof pressure reducing proportional valves, pilot operated, in compliance with ATEX 94/9/EC standards. They are suitable for use in potentially explosive atmospheres, that fall within the ATEXII 2GD either for gas or for dust classification.  The pressure can be modulated continuously in proportion to the current supplied to the solenoid.  They can be controlled directly by a current control supply unit or by means of an electronic card to exploit valve performance to the full.  They are available with CETOP P05, ISO 4401-05 (CETOP R05), ISO 4401-07 (CETOP 07) and ISO 4401-08 (CETOP 08) mounting surfaces.  The statement of conformity to the up mentioned standards is always supplied with the valve.  Upon request, DZCE*KD2valves can be supplied with a finishing surface treatment (zinc-nickel) suitable to ensure a salt spray resistance up to 600 h (test operated according to UNI EN ISO 9227 standards and test evaluation operated according to UNI EN ISO 10289 standards).

The explosion-proof directional proportional valves are in compliance with ATEX 94/9/EC standards and are suitable for the use in potentially explosive atmospheres, that fall within the ATEX II 2GD either for gas or for dust classification. See par. 4 for ATEX classification, operating temperatures and electrical characteristics.  These valves are direct operated type, ISO 4401-03 (CETOP 03) size and pilot operated type, CETOP P05, ISO 4401-05 (CETOP R05), ISO 4401-07 (CETOP 07), ISO 4401-08 (CETOP 08) and ISO 4401-10 (CETOP 10).  With the valve and the distributor the statement of conformity to the up mentioned standards is always supplied.  The DSE3KD2 valves are supplied with a finishing surface treatment (zinc-nickel) suitable to ensure a salt spray resistance up to 600 h (test operated according to UNI EN ISO 9227 standards and test evaluation operated according to UNI EN ISO 10289 standards); for DSPE*KD2 valves, this treatment is available upon request.
