Spring pack

• Function control
• Constant installation height
• Particularly safe disassembly

Function control

With the adjusting screw being flush with the cone spindle, the stroke of the valve is visible on the adjusting screw. Thus the function of the installed valve can be controlled under operational conditions.

Compact design

The valve installation height remains constant after the pressure range has been set or changed. Thus the valve can be easily incorporated into the pipe system.

Safety during maintenance

Using a spring pack that rests at the spring cap will prevent tension when the spring cap is separated from the valve body. During disassembly the valve parts will not become dislodged in an uncontrolled way, even if the spring has not been released by mistake. Thus the valve ensures a particularly safe disassembly.

Additional safety in case of leakage hazard

Thanks to the O-ring seal of the adjusting screw and the connection of a so-called leakage line the valve is always hermetically sealed also in case of damage to the control element (diaphragm, piston or bellows). Thus the German rules for prevention of accidents (UVV) and the rules of the trade association BG for the handling of hazardous media are complied with. In addition, the connection of a manometer enables an easy function control.
