  1. Groth Corp Model 1200A Pressure / Vacuum Relief Valve

    Groth Corp. Model 1200A Pressure / Vacuum Relief Valve

    Model 1200A is designed to vent to atmosphere to protect your tank from damage created by over-pressure or excessive vacuum. Costly product evaporation losses due to normal tank "breathing" are greatly reduced. Because the Model 1200A retains toxic vapors, atmospheric contamination is minimized. This helps to provide increased fire protection and safety.
  2. Groth Corp Model 1220A Pressure/Vacuum Relief Valve w/Pipe-Away

    Groth Corp. Model 1220A Pressure / Vacuum Relief Valve w/ Pipe-Away

    Model 1220A is used for pressure and vacuum relief where vapors must be piped away. Special pallets in the Model 1220A housing virtually eliminate the intake of air and the escape of vapors except during normal tank breathing, thus reducing the loss of product and protecting the tank from possible damage. Escaping vapors are piped away through a flanged outlet connection. This helps to provide increased fire protection and safety.
  3. Groth Corp Model 1260A Pressure Relief Valve w/Pipe-Away Feature

    Groth Corp. Model 1260A Pressure Relief Valve w/ Pipe-Away Feature

    Pressure Relief Valve Model 1260A is for use where pressure relief is required and all relieving vapors must be piped away. Tank relief, to avoid tank damage, is controlled by a spring or weight loaded pallet in the valve housing. Pressure relief valves help provide increased fire protection and safety. The Model 1260A can also be used for in-line vacuum relief where flanged inlet connection is required.
  4. Groth Corp Model 1300A Vacuum Relief Valve, Top Mount

    Groth Corp. Model 1300A Vacuum Relief Valve, Top Mount

    The Groth Model 1300A Vacuum Relief Valve is used when vacuum relief is the only requirement. Intake relief necessary under working conditions is achieved by a spring or weight loaded pallet. This feature of the Model 1300A reduces the possibility of tank damage. The Model 1300A helps to provide increased fire protection and safety.
  5. Groth Corp Model 1360A Vacuum Relief Valve, Side Mount

    Groth Corp. Model 1360A Vacuum Relief Valve, Side Mount

    The Groth Model 1360A Vacuum Relief Valve is used when vacuum relief is the only requirement. The Model 1360A may be side mounted on the tank body or piped in. Intake relief necessary under working conditions is achieved by a spring or weight loaded pallet in the valve housing. The Model 1360A reduces the possibility of tank damage and provides increased fire protection and safety.
  6. Groth Corp Model 1720A Pressure/Vacuum Relief Valve w/Pipe-Away Feature

    Groth Corp. Model 1720A Pressure / Vacuum Relief Valve w/ Pipe-Away Feature and Same-Size Inlet & Outlet

    Groth Series 1700 relief valves are designed with inlet and outlet flanges of the same size to reduce installation costs by having smaller downstream piping. Model 1720A valves are designed for systems requiring pressure and vacuum relief. Escaping vapors are piped away through a flanged outlet connection, helping to provide increased fire protection and safety.
  7. Groth Corp Model 1760A Pressure Relief Valve w/Pipe-Away Feature

    Groth Corp. Model 1760A Pressure Relief Valve w/ Pipe-Away Feature and Same-Size Inlet and Outlet

    Groth Series 1700 relief valves are designed with inlet and outlet flanges of the same size to reduce installation costs by having smaller downstream piping. Model 1760A valves are designed for systems requiring only pressure relief. Escaping vapors are piped away through a flanged outlet connection. This helps to provide increased fire protection and safety.
  8. Groth Corp Model 1800A Series Full Lift Type Valve

    Groth Corp. Model 1800A Series Full Lift Type Valve

    The Groth 1800A Series Full Lift Type Valve is for applications requiring low fugitive emissions and operation near tank MAWP. A Full Lift Type Valve is a relief valve which attains full stable lift at only 10% overpressure. Like all Groth Pressure/Vacuum Relief Valves, the Full Lift Type Valve is a modulating valve which offers near zero blow down, meaning it reseats at set pressure. This technology is possible due to the harmonization of the nozzle, seating, and pallet areas such that the valve will achieve stable lift at only 10% above the set pressure/vacuum.
  9. Groth Corp Model 8800A Pressure/Vacuum Relief Valve and Flame Arrester

    Groth Corp. Model 8800A Pressure / Vacuum Relief Valve and Flame Arrester

    The Groth Model 8800A is a combination of the 1200A Pressure Vacuum Relief Valve and Groth Model 7618 Flame Arrester. The superior Buna-N seating diaphragms are standard on the valve to insure extra tight sealing to prevent sludge vapors escaping. Self draining housing body and drip rings protect seating surface from condensate and freezing. The 1200/7618 helps protect your tank from damage created by overpressure or excessive vacuum, at the same time it provides protection from externally caused sources of heat and ignition. The result is reduced emissions level and increased fire protection and safety.
  10. Groth Corp. Model 8800SDV Pressure / Vacuum Relief and Flame Arrester w/ Safety Diverter Valve

    Groth Corp. Model 8800SDV Pressure / Vacuum Relief and Flame Arrester w/ Safety Diverter Valve

    The Groth Model 8800SDV is a pair of Groth Model 8800 assemblies (which consist of the 1200A Pressure Vacuum Relief Valve and the 7618 Flame Arrester in series) mounted to a three-way safety diverter valve to allow for maintenance. See the 8800 literature for technical information.
