MODEL 12F-TW0

Weight Loaded Pressure Relief Valve

The Groth Corporation Model 12F-TW0-0 weight loaded pressure relief valve is designed to be used in applications where additional relief is necessary. It can be used in conjunction for emergency relief but that is not why it was designed. Pressure relief valves provide relief from excessive internal pressure which may cause tank damage.

Superior Sealing Performance

• Precision machining and manufacturing to accomplish superior sealing
• Ultra-tight sealing reduces product leakage and fugitive emissions
• Leak Rate is compliant with API 2000

Industry Leading Flow Rates

• Higher flow capacity to protect from excessive pressure build up
• Higher flow rates also allow these valves to be used in a wider range of applications
than valves with lower flow rates

Direct Replacement & Easy Maintenance

• Direct replacement for any standard pressure relief valve
• Designed for easy maintenance, thus reducing downtime and lowering operational costs
• Fully field replaceable pallet assemblies
• Replacement pressure diaphragms “soft goods”
