Model 12F-TSO
Groth Pressure Relief Valve (PRV) - Spring Loaded, Pipe Away Body

The new Groth Models 12F-TS0 PRV, spring loaded designs safeguard tanks from damage created by overpressure. Costly product evaporation losses due to normal tank “breathing” are greatly reduced. Because the 12 Series products retain toxic vapors, atmospheric contamination is minimized which helps to provide increased fire protection and safety.

              • Utilizes the latest 10% overpressure technology for full lift in+10% of the setpoint
              • Full rated flow capacity achieved at 10% over-pressure
              • Pressure Settings: 1 psig to 15 psig (69 to 1039 mbar)
              • Cushioned air seating
              • Superior performing fluoropolymer diaphragms
              • Self-draining housing body and drip rings protect seating surfaces from condensate and freezing, increasing operational reliability
              • Superior performing fluoropolymer diaphragms

              • Product leakage and fugitive emissions are reduced via ultra-tight sealing
              • Higher flow capacity to protect from both excessive pressure and excessive vacuum build up
              • Peripheral and central seat guides ensure reliable, repeatable performance
              • Designed for easy maintenance, thus reducing downtime and operational cost
              • Superior tightness, meeting API-2000 leak requirements

Model 23E-TWO
Groth Pressure Relief Valve (PRV) - Weight Loaded, Atmospheric Venting with Rain Hood

Groth Corporation's new Model 23E-TW0-0 weight loaded pressure relief valve is designed
to be used in applications where additional pressure relief is necessary. Pressure relief
valves provide relief from excessive internal pressure which may cause tank damage.

Model 1760A
Groth Pressure Relief Valve (PRV)

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.

    • Cushioned Air Seating
    • Center and peripheral pallet guiding
    • Self-draining body
    • Fluoropolymer seating diaphragms minimize sticking caused by resinous vapors and atmospheric moisture
    • Self draining housing body and drop rings to protect seating surfaces from condensate and freezing
    • Design avoids pressure or vacuum buildup due to binding or clogging of the valve

    Data Sheet

Model 1260A
Groth Pressure Relief Valve (PRV)

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.Back pressure in the system must be considered when using flow curves.

              • The flanged outlet connection allows escaping vapors to be piped away, instead of released directly to the atmosphere
              • Peripheral and central seat guides ensure reliable, repeatable performance
              • A wide seat and air-cushion seal keeps leakage low long after the valve is put in service
              • Self-draining housing body and drip rings protect seating surfaces from condensate and freezing, increasing operational reliability
              • Fluoropolymer seating diaphragms are standard to minimize sticking caused by resinous vapors and atmospheric moisture

Model 2300A
Groth Pressure Relief Valve (PRV)

The Groth Model 2300A Emergency Relief Valve is designed to vent to atmosphere for emergency relief capacity above that supplied by a standard operating valve used on tanks, piping, and low pressure vessels. Emergency relief valves provide relief from excessive internal pressures which may cause tank damage.

Model 2300A is built of corrosion resistant material throughout. Groth’s self-closing special fluoropolymer “cushioned air” pallet with center stabilizing stem and peripheral guiding provides uniform seating and alignment. Superior performing fluoropolymer seating diaphragms are standard to minimize sticking caused by resinous vapors and atmospheric moisture. The guides support a spun weatherhood which covers and protects the entire valve structure. As added protection against the entry of foreign matter, a mesh screen encircles the valve under the weatherhood.

              • Can be used for emergency relief on smaller tanks
              • Peripheral and central seat guides ensure reliable, repeatable performance
              • A wide seat and air-cushion seal keeps leakage low long after the valve is put in service
              • Self-draining housing body and drip rings protect seating surfaces from condensate and freezing, increasing operational reliability
              • Fluoropolymer seating diaphragms are standard to minimize sticking caused by resinous vapors and atmospheric moisture
