Models
SP80 and SP100 belong to the Spirax Sarco series of high-capacity, pilot-operated bimetallic steam traps. The primary difference is connection size: SP80 is DN80, while SP100 is DN100. Both feature cast steel bodies and a Class 300 design, support PN40, ANSI 150, and ANSI 300 flanged connections, have a maximum operating temperature of 300°C and a maximum backpressure of 90% of upstream pressure, and are available with N-type or E-type pressure configurations according to operating conditions. For selection, first choose SP80 or SP100 according to the pipe size, then select the N-type or E-type according to operating pressure: the N-type is rated for 0.5 to 3 bar g, and the E-type for 1.5 to 21 bar g. Also confirm that the flange pressure-temperature rating and operating range meet the application requirements.

Application scenarios
High-Volume Condensate Discharge from Large Steam Heat Exchange Equipment
Suitable for condensate discharge applications in large steam heat exchange equipment. SP80 and SP100 are specifically designed for high-flow applications and provide DN80 or DN100 flanged connections; during system startup, they rapidly discharge cold water, air, and non-condensable gases, with the discharge temperature externally adjustable.
Selection points
Pilot-operated bimetallic design for large nominal sizes
SP80 and SP100 are pilot-operated bimetallic steam traps with DN80 and DN100 flanged connections, respectively, suitable for selecting equipment for high-volume steam condensate discharge.
N-type and E-type pressure range classifications
The N-type is suitable for operating pressures from 0.5 to 3 bar g, while the E-type is suitable for operating pressures from 1.5 to 21 bar g. Select the appropriate model according to the actual operating pressure of the steam system.
Externally adjustable discharge temperature
The discharge temperature setting of this series can be adjusted externally to meet process drainage requirements.
Installation & maintenance notes
Match the operating pressure to the N-type or E-type model
Before installation, verify that the site operating pressure matches the selected model. SP80N and SP100N have an operating pressure range of 0.5 bar g to 3 bar g, while SP80E and SP100E have an operating pressure range of 1.5 bar g to 21 bar g.
Keep downstream backpressure below 90% of upstream pressure
During installation, ensure that downstream backpressure does not exceed 90% of upstream pressure to comply with the maximum backpressure limitation of SP80 and SP100.
FAQ
What operating conditions are SP80 and SP100 bimetallic steam traps suitable for?
This series consists of pilot-operated bimetallic steam traps with cast steel bodies and integral strainers, designed specifically for high-flow applications. During system start-up, they rapidly discharge air, non-condensable gases, and cold water, and can withstand a certain degree of superheat.
How should the N-type or E-type pilot valve be selected for SP80 and SP100 based on inlet pressure?
Select the N-type pilot valve when the inlet pressure is below 3 bar g, and the E-type pilot valve when the inlet pressure exceeds 3 bar g. The N-type has a maximum operating pressure of 3 bar g, while the E-type has a maximum operating pressure of 21 bar g.
What are the sizes and connection standards for SP80 and SP100?
SP80 has a DN80 size, and SP100 has a DN100 size. Both support PN40, ANSI 150, or ANSI 300 flanged connections. The specific configuration must be confirmed according to the actual model and operating conditions.
What additional parameters are required for SP80 and SP100 selection?
In addition to the inlet pressure, the downstream pressure must be confirmed to calculate the operating differential pressure. The appropriate pilot valve type and seat specification should then be selected based on the required capacity. This series is available with N-type and E-type pilot valve assemblies and four seat sizes.
What replacement spare parts are available for SP80 and SP100?
Available spare parts include N-type pilot valve assemblies, E-type pilot valve assemblies, and disc assemblies. When ordering spare parts, specify the steam trap model and size. The specific configuration must be confirmed according to the actual model and operating conditions.
