Spring-Loaded Pressure / Vacuum Relief Valve – with Drain MODEL 12F-TSW
Description
The spring-loaded design of the Groth Model 12F-TSW pressure/vacuum relief valves was created to exceed industry needs. Extensive research and development have produced a product that achieves superior sealing performance and industry-leading flow rates, while allowing customers to achieve the required flow with a potentially smaller valve. The pressure/vacuum relief valve is designed to protect your tank from damage caused by overpressure or excessive vacuum. Costly evaporative product losses due to normal tank "breathing" are greatly reduced. Models 12E-TSW and 12F-TSW are top-sealing valves developed to minimize fugitive emissions while providing greater protection and safety for tank equipment and on-site personnel.
