Superior Sealing. Reduced Leakage. 10% Overpressure Protection.

Houston, TX, USA – Groth Corporation, a global leader in pressure and vacuum relief solutions, has released the Model 22E Emergency Relief Valve, engineered to deliver rapid overpressure protection with industry-leading sealing performance and exceptional flow rates.

Model 22E Emergency Relief Valve

 

Designed for API 2000 / ISO 28300 compliance, the Model 22E opens fully at just 10% overpressure, venting large volumes during fire or upset conditions to help prevent tank rupture.
