3 Terms and definitions
For the purposes of this European Standard, the following terms and definitions apply.
3.1
alarm device
mechanical or electrical device to sound an alarm on operation of the deluge valve
3.2
automatic drain (valve)
device, usually remaining open, which automatically drains water from the deluge valve
3.3
clapper
type of sealing assembly (see 3.19)
3.4
deluge system
automatic fire protection system using a deluge valve, which is operated by auxiliary means to admit water
into a system of sprayers
3.5
deluge valve
water supply control valve intended to be operated by an auxiliary means to admit water into a system of
piping with open sprayers
NOTE The auxiliary means of operating a deluge valve may be mechanical, electrical, hydraulic, pneumatic, thermal,
manual or a combination of these.
3.6
dry pilot actuator
differential type valve which permits the operation of a hydraulically operated deluge valve upon loss of
pneumatic pressure from a dry pilot line
3.7
dry pilot line
pneumatic detection and actuation piping system fitted with heat responsive devices, usually sprinklers, which,
when subjected to an abnormal source of heat, operate to release pressure from the piping system and dry
pilot actuator, causing the automatic operation of a deluge valve
3.8
flow velocity
water velocity through pipe of the same nominal size as the deluge valve at the same flow rate
3.9
hydraulically/pneumatically operated deluge valve
valve, maintained in the set condition by service hydraulic/pneumatic pressure acting against a diaphragm or
piston that holds the sealing assembly closed
NOTE A change in pressure against the diaphragm or piston allows the valve to open.
3.10
mechanically operated deluge valve
deluge valve, maintained in the set position by mechanical means and released mechanically, e.g. by the
action of a release weight
3.11
minimum service pressure
lowest static water pressure required at the inlet to the deluge valve in the ready condition

3.13
priming water
water to be provided at the outlet of the valve ready condition
3.14
supply-pressure operated deluge valve

application of supply pressure to an auxiliary diaphragm or piston
3.15
ready (set) condition
state of the deluge valve, fully assembled, with sealing assembly in the set position with the service pressure
applied
3.16
reseating prevention
avoidance of the sealing assembly returning to the closed position
3.17
resetting (valve)
returning of the valve to the ready (set) condition
3.18

main movable sealing element of the deluge valve (e.g. clapper)
3.20
sealing assembly seat ring

point at which the deluge valve operates, admitting water into the deluge system piping, measured in terms of
the pilot line pressure and service pressure and expressed as a ratio
3.24
water motor alarm
hydraulically actuated alarm device (see 3.1) fitted to the deluge valve to provide a local audible alarm when
the deluge system operates
3.25
water motor transmitter

deluge valve.
4.2.2 Connections to the valve body or pipework
4.2.2.1 If priming water is required for sealing or damping purposes, external means shall be provided to
allow priming water to enter.
4.2.2.2 Means shall be provided to facilitate testing of alarms without tripping the deluge valve.
4.3 Pressure and flow limits
The nominal working pressure shall be specified by the supplier and shall be not less than 12 bar.
NOTE Inlet and outlet connections may be machined for lower working pressure in order to match installation
equipment of a lower working pressure.
The minimum service pressure shall be specified by the supplier and shall be not less than 1,4 bar.
The maximum allowable steady state flow shall be specified by the supplier.
4.4 Bodies and cover
4.4.1 Materials
The body and any cover shall be made of cast iron, bronze, brass, Monel metal, stainless steel or titanium or
materials with equivalent physical and mechanical properties.
If non-metallic materials (other than for gaskets and pipe seals) or metals with melting point of less than
800 °C form part of the deluge valve body and any cover, the assembled deluge valve shall conform to 4.10.1
and the sealing assembly shall open freely and fully when tested in accordance with Annex A.
4.4.2 Configuration
The deluge valve cover plate (if fitted) shall not be assembled in a position which affects the operation of the
valve so that it does not conform to this European Standard, in particular indication of flow direction, see 6.2 d).
4.4.3 Strength
4.4.3.1 The assembled deluge valve with the sealing assembly open s
