◉ Increase the amount of blowdown. Answer: Raising the blowdown
ring on a pop safety valve will
◉ Vertical. Answer: The safety valve on steam boiler shall be
installed in the _____ position and located in the highest practicable
part of the heating boiler proper
◉ Stop Valve. Answer: Device that is NOT allowed before or after the
safety valve
◉ Melting of the alloy in a fusible plug. Answer: Temperature relief
valves can open on a rise in temperature by the expansion of a wax-
filled rod or by the
◉ Adjusting Ring. Answer: The blow down on a safety valve is
adjusted by turning the

safety valve disc is a function of the
,◉ Seal. Answer: Device that a boiler inspector will install in order to
prevent tampering with a safety valve setting
◉ Increasing the boiler pressure until the valve opens, noting the
popping pressure. Answer: An operator should check that a boiler
safety valve will open at its set pressure by
◉ False. Answer: The safety valves on the drum of a steam heating
boiler can be installed on an angle as long as they are mounted at a
perpendicular to the drum (True or False)
◉ ASME Section IV. Answer: The current code that covers hot water

seat diameter of the safety valve on a steam heating boiler must not
be smaller than
, ◉ Hold down the disk on the seat. Answer: The purpose of the
spring in a safety valve is to
◉ Increase spring compression. Answer: To increase the opening
pressure of a safety valve
◉ Try Lever Safety Valve Test. Answer: Done in order to ensure the
valve is free to operate
◉ True. Answer: Lowering the blowdown ring on a safety valve will
decrease the amount of blowdown (True or False)
◉ 30 kPa. Answer: According to the current code the maximum
blowdown for a steam heating boiler safety valve is
◉ 75% working pressure. Answer: Do not open the safety valve with
the test lever if the pressure is less than
◉ Allowance for expansion prevents stress on the safety valve.
Answer: The discharge pipe of a safety valve should be separately
supported so that
