General

• Spring loaded Safety Valve

• Certified according to

• ASME Code Sec. I (V-Stamp)

• ASME Code Sec. III (NV-Stamp)

• ASME Code Sec. VIII (UV-Stamp)

• NBBI (National Board of Boiler and Pressure Vessel Inspectors) certified capacity for steam

• PED 97/23/EC certified

• Overpressure 3% of set pressure

Features and Benefits

• High capacity

• Without nozzle rings, this means no adjustment for blow down required

• Stable position of the disc by mechanical lift stop at full lift

• Optimized disc/spindle connection for high seat tightness

• Forged monoblock inlet nozzle for welding connection

• Special disk spring design for high pressures and large orifice diameters

• Hard faced seat areas on nozzle and disc

• Easy maintenance

• New setting after maintenance of the valve is not necessary because of an integrated locking device for the spring

• Locking possibility for hydrostatic test without valve disassembly

• Valve function is stable up to 25%built up backpressure

The example specifies a safety valve with a flanged 3" class 2500, an orifice diameter of 52 mm and a 4" class 600 flanged outlet. The valve has a coil spring, a lifting device and the valve is blockable for the hydrostatic test without any disassembling. The disc of the valve is hardfaced and the body material is SA-216 WCB.

Capacity formula for USCS Units:

W = 51.5 × A × P

For pressures over 1500 psig and up to 3200 psig, the value W shall be multiplied by the correction factor:

0.1906P – 1000 0.2292P – 1061

Capacity formula for SI Units:

W = 5.25 × A × P

For pressures over 10.3 MPa and up to 22.1 MPa, the value W shall be multiplied by the correction factor:

27.6P – 1000 33.2P – 1061

where:K = 0.826A = Flow area, in sq.in = (d0/25,4)2π/4P = (1.03 × set pressure + 14.7)or:P = (set pressure + 2 + 14.7)whichever is greater, in psia.

where:K = 0.826A = Flow area, in mm2 = d02π/4P = (1.03 × set pressure + 0.101)

or:P = (set pressure + 0.014 + 0.101)whichever is greater, in MPa.

W = 51.5 x A x P

For pressures over 1500 psig and up to 3200 psig, the value W shall be multiplied by the correction factor:0.1906P – 10000.2292P – 1061

where: K = 0.826A = Flow area, in sq.in = (d0/25,4)2π/4P = (1.03 x set pressure + 14.7) or P = (set pressure + 2 + 14.7)whichever is greater, in psia.

Berechnungsformel für SI Einheiten:

W = 5.25 x A x P

Für Drücke zwischen 10.3 MPa und 22.1 MPa ist der Wert W mit folgendem Korrekturfaktor zu multiplizieren.27.6P – 100033.2P – 1061 mit: K = 0.826A = Strömungsquerschnitt, in mm² = d02π/4P = (1.03 x Ansprechdruck + 0.101) or P = (Ansprechdruck + 0.014 + 0.101)der größere Wert ist zu verwenden, in MPa.

W = 51.5 x A x P

For pressures over 1500 psig and up to 3200 psig, the value W shall be multiplied by the correction factor:0.1906P – 10000.2292P – 1061

where: K = 0.826A = Flow area, in sq.in = (d0/25,4)2π/4P = (1.03 x set pressure + 14.7) or P = (set pressure + 2 + 14.7)whichever is greater, in psia.

Berechnungsformel für SI Einheiten:

W = 5.25 x A x P

Für Drücke zwischen 10.3 MPa und 22.1 MPa ist der Wert W mit folgendem Korrekturfaktor zu multiplizieren.27.6P – 100033.2P – 1061 mit: K = 0.826A = Strömungsquerschnitt, in mm² = d02π/4P = (1.03 x Ansprechdruck + 0.101) or P = (Ansprechdruck + 0.014 + 0.101)der größere Wert ist zu verwenden, in MPa.
