POWERFLO Safety and Relief Valves

Fig. 1479 and 1551 Medium Capacity for air, steam, gas or liquidThis is a medium capacity low priced valve meeting the AS1271 requirements, providing the optimum product to meet theseverest demands.

Important features of the valve are its positive sealing, sharp, clean opening and ease of adjustment.

The POWERFLO 1479 and 1551 Bronze Safety and Safety Relief Valves are offered in 15 and 20mm sizes for steam, air orliquid service in a variety of combinations for pressures up to 2050kPa. They are available with screwed bases, with brassbase and disc as standard.

Designed specifically for air, steam, gas and liquid service, POWERFLO Valves will meet all the varied needs of Industrytoday. POWERFLO Valves are engineered and manufactured to meet the most exacting requirements of industry for positiveand dependable operation.

Users of POWERFLO Safety Relief Valves benefit by the accumulated experience of more than 100 years of development,engineering, manufacturing and field experience in safety and relief valve design for the protection of all types of pressurevessels and systems.

The purpose of a safety valve or relief valve is protection of personnel, plant and production. To perform this basic function,a safety relief valve must be designed to open automatically at a predetermined set pressure, must be sized to provide fullpressure relief of the pressure system on which it is installed, must provide positive closing and tightness after operation. ThePOWERFLO Safety Valve will provide this basic function.

POWERFLO Safety Valves are engineered to make use of the characteristics of air, steam or gases which have a powerfulexpansion force when liberated. This force, and kinetic energy of the media flowing from the valve orifice, is fully utilised togive the definite pop action associated with POWERFLO Safety Valves.

The full advantages of these two factors, coupled with the carefully developed contours of the POWERFLO Safety Valvehuddle chamber, increase the valve lift and therefore increase the capacity of the valve. Different media, with varying specificgravities can cause the valve to perform in different ways. To allow for this, the POWERFLO 1541/1543 Safety Valve isdesigned with two performance adjusting rings. The upper adjusting ring controls the blowdown by redirecting the flow streamthrough 1800 through a secondary orifice, the size of which is adjusted to achieve maximum valve lift.

CALCULATED IN ACCORDANCE WITH AS1271-2003 AND AS3653-1993


NOTES:1. The outlet line must be short as possible and its weight fully supported.2. A back pressure limitation of 276 kPag applies.3. The built-up back pressure shall not exceed 10% of the set pressure.4. Valves are not suitable for corrosive, flammable or toxic service.5. Capacities at set pressures below 207 kPag are based on 20.7 kPag overpressure.6. The maximum pressure for the bronze 1541 and 1543 is 1700 kPag. The figures in italics are for

1541-3 and 1543-3 with SST base and disc, which is limited to 2050 kPag on steam service.

1. Valves are not designed for closed discharge systems. The outlet line must be short as possible, open toatmosphere and its weight fully supported.

2. A back pressure rating of 270 kPag applies only to built-up back pressure conditions, which shall notexceed 10% of the set pressure.

3. A lifting lever will be required on hot water applications where operating temperature exceeds 60 degreesCelsius, so the SPL suffix should not be nominated.

4. Valves are not suitable for corrosive, flammable or toxic service.5. For values of set pressure below 300 kPa, the blowdown shall be a minimum of 60 kPa.6. Nameplate will continue with L being stamped in the capacity box.

BACK PRESSUREBACK PRESSUREBACK PRESSUREBACK PRESSUREBACK PRESSUREDEFINITIONDEFINITIONDEFINITIONDEFINITIONDEFINITION

Back pressure is that pressure foundin the valve body casing and in theexhaust piping from the valve. It isdownstream from the valve nozzle anddisc seat and may affect valveperformance and capacity. Types ofback pressure include:

Super-imposed it exists in the valvebody casing and exhaust piping priorto the valve opening. It consists ofthree types:

Atmospheric normalatmospheric pressure is presentand has no effect on the setpressure or performance of a valveset above 100 kPag.

Constant pressure (higher thanatmospheric) that exists in thebody casing and exhaust piping,but which does not change withtime.

Variable pressure that exists inthe body casing and exhaustpiping, but which is variable innature and changes with time.

Built-up pressure on the exhaustside of the valve that results from flowthrough the valve, after the valve hasopened.
