Description
Surge relief valves are used for the decay of pressure surges and of
permanent overpressures within pipeline systems.
SR 6.2K and SR 6.2P are self-energized valves with lowest possible
response times. They operate without any auxiliary or external energy.
The body is of welded design and, therefore, very lightweight
compared with cast ones. Building length, connections and materials
can be customised to any requirement. The straightway valve with
optimised design features the least possible flow loss. The valve cone is
of the soft seal type.
SR 6.2K is directly acting with piston actuation. The response pressure
has been pre-set.
SR 6.2P is pilot-controlled, the response pressure and the closing time
are adjustable. If a second pilot valve is used, the valve can be switched
to another pre-set response pressure.
At the control unit (closing piston) the inlet pressure is in balance with
the valve spring force (set value). If the inlet pressure rises above the set
value, the valve opens (in the pilot valve and/or in the inner chamber of
the main valve). With the inlet pressure falling the valve closes, driven by
the spring tension and the increasing pressure downstream of the
closing piston. In a depressurized line the valve remains closed.
The valves are completely tubed. Control lines or similar are not
required. The version for either horizontal or vertical installation can be
selected.
