Tailored To Your Tank Terminal Needs
The Model TP12100M is a pilot-operated valve specifically designed for tank blanketing. It automatically opens and closes as needed to maintain a closely controlled blanket pressure. The simple design increases reliability and reduces maintenance costs.
Typical Applications
- Blanketing of medium and large tanks
Benefits
- Lower maintenance costs are achieved through fewer parts, and replacement parts are cost-effective.
- Standard valve materials offer additional corrosion protection without extra charges.
- The valve design ensures integrity and safeguards against personnel injury.
- Achieving a bubble-tight seal at the set point prevents the wasteful release of blanketing gases.
Features
- Single valve system Compact and lightweight
- Pressure-balanced pilot
- Set point unaffected by supply pressure fluctuations
- Utilizes standard O-rings
- Top entry design for easy maintenance
- Set points ranging from vacuum to 14 psig
- Self-cleaning flow design for both the main valve and pilot
- Temperature changes have no appreciable effect on the set point
