Models
IBPS32 is the standard maintainable balanced pressure thermostatic steam trap explicitly supported by the product documentation. It has a stainless steel body, an integral Y-strainer and Spiratec sensor, with STD, NTS or SUB fill capsules available to suit the required drainage temperature. IBPS32CV appears in the known model list and among the candidate variants, but the available product documentation does not clearly describe its structural difference from IBPS32 or its check valve configuration. Its intended selection cannot therefore be confirmed solely from the candidate description.
IBPS32Spirax Sarco standard balanced pressure thermostatic steam trap
IBPS32 is a maintainable balanced pressure thermostatic steam trap with a 316 Ti austenitic stainless steel body, an integral Y-type stainless steel strainer and Spiratec sensor. It can detect condensate accumulation and steam leakage, or steam leakage only. The body has a PN40 design pressure rating, a maximum saturated steam pressure of 32 bar g and a maximum operating temperature of 240°C at 32 bar g. The standard STD fill capsule drains condensate at 12°C below steam saturation temperature. NTS or SUB fill capsules can also be selected to provide drainage at 6°C or 24°C below steam saturation temperature, respectively.

Installation & maintenance notes
Verify operating pressure and temperature
Before installation, verify the actual pressure and temperature of the steam system to ensure they remain within the permissible operating range of IBPS32. The maximum saturated steam pressure is 32 bar g, and the maximum operating temperature at 32 bar g is 240°C.
Confirm Spiratec sensor monitoring configuration
When installing or configuring IBPS32, confirm the integral Spiratec sensor function required for the application. The sensor can detect condensate accumulation and steam leakage, or steam leakage only.
FAQ
Which fill capsule types are available for IBPS32, and how do their drainage temperatures differ?
The standard configuration uses an STD fill capsule and drains condensate at 12°C below steam saturation temperature. An NTS fill capsule is available for drainage at 6°C below saturation temperature, and a SUB fill capsule is available for drainage at 24°C below saturation temperature. Specify the fill capsule type when ordering.
What is the difference between IBPS32 and IBPS32CV?
IBPS32 is the standard balanced pressure thermostatic steam trap with an STD fill capsule. IBPS32CV has an STD fill capsule and a check valve. Confirm the exact configuration according to the model and application conditions.
What sizes and connection types are available for IBPS32?
Available sizes include 1/2 inch, 3/4 inch and 1 inch, corresponding to DN15, DN20 and DN25. Connection options include BSP or NPT threads, BS 3799 socket weld, EN 12627 butt weld, and EN 1092 PN40, ANSI B16.5 Class 150/300, JIS/KS 10K and 20K flanges.
What are the main operating limits of IBPS32?
The body design rating is PN40. The maximum allowable pressure is 50 bar g at 50°C, the maximum saturated steam pressure is 32 bar g, the maximum operating temperature is 240°C at 32 bar g, and the minimum operating temperature is 0°C. The maximum cold hydraulic test pressure is 75 bar g.
What should be considered during IBPS32 installation and condition monitoring?
Install the fill capsule in a horizontal position with the cover at the top. Where downstream backpressure is present, a check valve is recommended at the outlet. For direct discharge to atmosphere, a silencer is recommended at the outlet. Suitable isolation valves should be installed upstream and downstream to facilitate maintenance. A WLS1 sensor can be used to detect condensate accumulation or steam leakage, while an SS1 sensor can be used to detect steam leakage. The trap can be connected to a Spiratec monitoring system.
