An Ideal Replacement Valve: Varec 2010B
An Ideal Replacement Valve: Varec 2010B
If you are looking for a replacement valve, consider the Varec 2010B. These weight-loaded relief valves protect tanks from damage or deformation and minimize emissions and loss of product due to evaporation.
  • These valves come in both vent-to-atmosphere or pipe away models.
  • The modular design provides flexibility of field installation and allows easy reconfiguration, repair, or on-site upgrading.
  • Oversized pressure and vacuum ports provide maximum flow capacity.
Enhanced Sealing and Emissions Compliance:<br>Enardo ES-850 and ES-950
Enhanced Sealing and Emissions Compliance:
Enardo ES-850 and ES-950
Both the Enardo ES-850 and ES-950 protect against positive overpressure and evaporative loss of product, and also suppress odorous and potentially hazardous vapors. Here’s how they work: when overpressure occurs, the weighted pallet lifts, breaking the seal between the seat and pallet, allowing vapors to pass through the valve orifice and relieving the pressure or vacuum buildup. The valve then reseals upon relief and remains sealed.
Superior Monitoring Capabilities: Anderson Greenwood 9300H
Superior Monitoring Capabilities: Anderson Greenwood 9300H

When maximum reliability is desired, the Anderson Greenwood 9300 Low Pressure Pilot Operated Relief Valve is king. Here’s why: the opening and closing of these relief valves can be monitored by measuring the differential pressure between the main valve dome and valve inlet. This technology can provide real-time information, enabling you to proactively develop corrective actions, optimize maintenance schedules, and improve asset management while reducing emissions. Immediate notification of relief events helps keep workers safe and ensures compliance with environmental regulations.
