FEATURES:
poppet valve
!
simple design
!
unidirectional, uniform flow
!
triggered elecromagneticly
!
available with two types of solenoid triggers:
!
WE (12V DC) or EZB-12,6G (230V AC)
low weight (mass)
!
bistable - in lack of voltage condition the valve could stay in one of stable
!
position: open or close.
Control voltage is necessary or valve closing only.
opened only manualy ("memory" function)
!
closed with electrical impulse
!
has the option for manual closing with botton
!
permanent strainer built-in
!
adapted for external application
!
conforms to PN-EN 161:2011+A3:2013
!
meets applicabe requirments of Regulation (UE) 2016/426 (GAR) from
!
9 march 2016 y. and Directives UE:
2014/35/UE (LVD); 2014/30/UE (EMC)
APPLICATION:
in Gas Safety Systems installed: gas boiler rooms, industrial facilities,
!
public utility buidings, domestic installations (i.e.one family houses and
multi-family houses, farmsteads, private use recreational buildings),
reducing -measuring stations, biogas plants, etc. itp. - as an actuator
that surely and effectively cuts off the gas supply to faulty installations
when a gas presence is detected in supervised by System compartments
in gas installations supplied in conformance with appropriate regulations
!
from low pressure gas grid
additionally valve can be used as manual stopcock, however it can not act
!
as gas installation main stopcock
together with gas detection system, valve can perform a function of lock-
!
up for devices that burn gas fuels and are intended for use inside the
buildings and utility compartments. Such a lock-up prevents from
accumulation of burning gas in mentioned buildings and compartments
