Pressure/temperature diagram
Pressure loss curve (standard values for H2O, 20°C)
∆P = pressure loss
Q = flow
pressure loss and kv value
The diagram shows the pressure loss ∆P in relation to the flow Q.
Conversion aid:
cv = kv x 0.07; fv = kv x 0.0585
Units:
kv [l/min]; cv [gal/min] US; fv [gal/min] GB
SRV 303: Opening pressure/closing pressure (mbar)
without spring
ps = Closing pressure
pö = Opening pressure
SRV 303: Opening pressure/closing pressure (mbar) with
spring
P = operating pressure
T = temperature
The pressure/temperature limits are applicable for the stated
nominal pressures and a computed operating life factor of 25 years.
These are standard values for harmless media (DIN 2403), to which
the valve material is resistant.
For other media please refer to the ASV resistance guide.
The durability of wear parts depends on the operating conditions
of the application.
For temperatures below 0°C (PP < +10°C) please specify the precise
operating conditions of the application.
The rated pressure depends on the valve size and material. For
the corresponding rated pressure value of the valve, please refer
to the »Order table«.

Angle Seat Check Valve SRV 303
Operating note
Safe operation of the valve can only be ensured if it is properly
installed, operated, serviced or repaired by qualified personnel
according to its intended use while observing the accident
prevention regulations, safety regulations, relevant standards,
directives/technical regulations or codes of practice such as e.g.
DIN, DIN EN, DIN ISO and DVS*. *DVS = German Welding Society
The intended use includes adhering to specified limit values for
pressure and temperature, as well as checking the resistance. This
requires all components coming into contact with the medium to
be "resistant" in accordance with the ASV resistance guide.
