| |||||
Notice:
Hydraulic counter pressures in port T add 1:1 to the response pressure of the valve set at the adjustment type.
Example:
- Pressure adjustment of the valve due to spring pretensioning (see "Product description" item 2) pspring= 200 bar
- Hydraulic counter pressure in port T: phydraulic = 50 bar
- ⇒ Response pressure = pspring + phydraulic = 250 bar
Deviating technical data: Type-examination tested safety valves type DBD
(Component series 1X, according to Pressure Equipment Directive 2014/68/EU)

| Maximum flow | The last but one figure of the component marking attached at the safety valve is always binding. For valve types which have a variable maximum flow depending on the response pressure, the discharge coefficient is specified at this place. | |||||||
