DESCRIPTION
ELECTRICAL CHARACTERISTICS – SOLENOID
The 200 SERIES is a range of diaphragm valves suitable for dust collector applications,
in particular for reverse pulse-jet filter cleaning of filter bags, cartridges, envelope
filters, ceramic filters and sintered metal fibre filters. The 200 Series valve has the inlet
port at 90° to the outlet port. The 200 Series range comprises 6 models, from ¾” to 2½”,
all with threaded female Gas connections. The 1½” model is available in single and double
diaphragm versions, while the 2” and 2½” are all double diaphragm valves. The special
design assures an extremely fast opening time, high flow rates and easy installation.
The valves are constructed in diecast aluminium and have an anodised protection
treatment which protect them from corrosive and environmental agents. Bolts and screws
are in stainless steel. The 200 Series is available in the following versions:
• VNP, with integrated solenoid pilot
• VEM, with remote pneumatic connection.
Upon request: Integral pilot valves with ATEX Certification: • ATEX II 3 D (94/9/CE); for the above approved
model the correct code to use is VEM+PV 24V/DCX (solenoid coil is 24 V-DC/18 W and DIN connector in conformity with the ATEX Directive 94/9/CE) (PLG11-ATEX).
Remote pilot valves meet the requirements of: • ATEX
II 2 GD when mounted with PXA Pilot or CXD Enclosure (94/9/CE).
