Miniature Advanced Pressure Relief Valve

Miniature Advanced Pressure Relief Valve

AUSCO Miniature Advanced Pressure Relief Valve designs offer a unique integral active damper and the unique ability to allow customer to specify an optimum flow curve trend

• Active integral damping allows for ultra stable flow performance over full flow range
• Wide range of standard designs. Custom designs available to meet customer-specified requirements
• Design sizes ranging from 0.281 in. to 2.0 in diameter; Dash 4 to Dash 24 fitting sizes
• Designs for safety relief (“pop-off”), pressurizing, filter bypass, and cross port functions for EHAs
• Allow for reduced pressure drop

Ability to Specify Gain Type

• High Gain (A) – Rapid opening for safety relief function
• Low Gain (B) – For low cost regulation
• Zero Gain (C) – Flat curve – Minimum pressure rise from cracking pressure to full flow – Higher reseat pressure equates to less leakage at operating pressure – Minimize power losses due to low leakage across valve
• Negative Gain (D) – Flow points below cracking pressure to compensate for other system component losses, allowing designer to meet overall system pressure drop requirement
