The main components of the safety valve are:
1
Lifting lever
2
Hat
3
Spring
4
Valve body
5
Cap
SC
Drain
IF
Fluid inlet
m
IMPORTANT
Before starting the generator, remove the steel wire that blocks the lever during transport. Make sure that the lifting lever
is free to move.
In case of conveyed drain, bracket the conveying pipe to compensate the reaction force generated when the fluid is drained.
Make one or more draining holes in the conveying pipe to drain any condensate.
Drain must take place in the atmosphere, direct the valve so as not to harm people or damage property.
Typical suggested scheme
Interception valves must not be provided.
The exhaust pipe must be designed in such a way that
any low temperatures do not create ice that ob-structs
the outlet.
N.B.: Bracket at no more than 1 m away
m
IMPORTANT
The operation of the safety valves is sensitive to pressure losses that occur in the drain conveying pipe during their
opening.The pressure losses in the drain conveying pipe of the safety valves must be 0.The nominal diameter of the
exhaust pipe must be greater than or equal to the size of the safety valve outlet connection.A diameter ≥ 1.5 DN (PSV)
is suggested.
