Safety Relief Valves
Summary
A safety relief valve is a pressure relief valve characterized by rapid opening or pop action, or by opening in proportion to the
increase in pressure over the opening pressure, depending on the application and may be used either for liquid or compressible fluid.
(1) Conventional Safety Relief Valve. A conventional
is a pressure relief valve
which has its spring housing vented to the discharge
side of the valve. The operational characteristics
(opening pressure, closing pressure, and relieving
capacity) are directly affected by changes of the
back pressure on the valve.
(2) Balanced Safety Relief Valve. A balanced safety
relief valve is a pressure relief valve which incorporates
means of minimizing the effect of back pressure
on the operational characteristics (opening pressure,
closing pressure, and relieving capacity).
