Model “C-AB” Relief Valve (Downstream Balanced / Angle Type Flanged)

Applications
Angle Type Flange End Relief Valve
Downstream Balanced
Standard Design for Valves 1/2 " to 48" Piston Diameter
Settings 2 PSI to 3,500 PSI Depending on Piston Diameter
Inlet and Outlet Flanges are Identical

Advantages
• Downstream pressure does not affect set point.
• Virtually no limit on size or special features.
• Excellent accuracy.
• Simplicity of only one moving part.
• Incredible reliability.
• The effect of downstream pressure balanced out. Downstream pressure does not change set point.

Rupture Pin Technology

> The rupture pin is not subject to premature fatigue failures and offers substantial savings in operating and maintenance costs.

> It is much more accurate than conventional devices on the market, especially at extreme pressures (low or high).

> The rupture pin itself is outside of your system – free from system temperatures and corrosion factors often experienced with rupture discs.

> Downstream pressure does not affect set pressure when a balanced piston is used.

> The pin is separate from your system piping, it can be quickly changed to reset. You won’t have to break into the integrity of your system to reset – which keeps you free from environmental concerns associated with other systems.

> Full open pressure relief occurs in milliseconds at set point – giving you better performance than rupture disks and spring loaded relief valves.

> The pin is replaced in only minutes which saves you time and money.
