Emergency Relief Vents

Key Features of the Groth Emergency Relief Vent include;

• Blow-off and Self Seating options

• Market-leading sealing performance – air cushion seat design creates a superior seal and is less prone to sticking than o-ring type seals

• Self Draining Pallets prevent build-up of water and potential to freeze shut/open

• There are no elastomers in Groth valves as they break down over time in common applications

• Construction in a broad range of materials including FRP

As with all Groth equipment, their ERV’s are manufactured to the highest standards and offer market-leading performance and longevity.

Groth ERV’s come with a range of standard and custom options as follows;

The Groth Model 2500A pilot-operated Emergency Relief Valve is designed to be self-closing – as excessive pressure builds up it relieves, then automatically reseats when overpressure has been dissipated.

Key Features of the Groth Pilot Operated Emergency Relief Vent include;

Key Features of the Groth Pilot Operated Pressure Relief Valve include;

• Documented compliance to EPA’s Method 21 testing (<500 ppm leakage at 90% of set pressure)

• ANSI 150# and API 650 drilling

• Full relief by 20% overpressure

• Trim available in 316 SS or Hastelloy C

• Designed to assist in meeting the requirements of the 1990 Clean Air Act Amendments as best available control technology.

• Provides the capability to meet the leakage rate requirement of 500 ppm or less. A pilot-operated valve with large actuator is the only proven way to ensure the necessary sealing force to meet the requirement.

• Built of corrosion-resistant materials throughout which allows it to be used in severe service environments such as with ethylene dichloride and methylene chloride.
