The single disc solution to leakage on flange joints subjected to high temperatures or severe thermal cycling conditions.

A single disc spring placed either side of the flange ensures:

• A constant uniform clamping force
• Compensation for thermal expansion and contraction
• The dampening of vibrational shock
• The prevention of gasket blowouts and reaction to pressure surges.

Geegraf NAS - Nickel Anti-Seize Lubrication

A high temperature anti-seize compound which when applied to disc springs and bolt threads reduces frictional drag. This reduces the torque required to generate constant travel of the disc assembly. Can be used on both valve and flange systems.
