Surge relief valve (peak load) for very high flow rates
Surge relief valves SR 6.2
The surge relief valve SR 6.2
is a self-energized valve with lowest possible response time. It operates 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.

Advantages
Flow-optimized construction (CFD)
Higher flow rate at lower differential pressure
1
Valve in welded construction
Low weight compared with others, adapted overall length, special materials and individual flange standards possible, short delivery times
2
Internal parts, pilot valve, piping and operating elements made of CrNiMo steel, painting as per
DIN ISO 12944 Teil 5 C5-M
High corrosion protection
3
Earthquake-proof
Can be used worldwide
4
Vacuum-tightSuitable for operation in the vacuum range
5
MOD Manual Opening Device
Function control, bleeding, flushing, filling of the valve
6
Pilot control, closing time and response pressure can be adjusted
Optimal response behaviour, gentle closure protecting the plant
7
Spin-on filter in the pilot system
Filter replacement is possible during ongoing operation, trouble-free function
8
Balanced cone, customer-specific KVS value
High seat tightness up to response pressure, smaller slop tanks possible, independent from counterpressure
