Zoloto 1055 Bronze Thermodynamic Steam Trap – Screwed End with Integral Strainer
Zoloto 1055 Bronze Thermodynamic Steam Trap with integral SS strainer. 250 psig working pressure, screwed BSPT ends. Ideal for industrial steam systems.

Overview
The Zoloto 1055 is a thermodynamic steam trap designed for efficient condensate removal in industrial steam systems. Built with a robust bronze body conforming to IBR 282 standards, this steam trap is engineered for reliable performance in process plants, utilities, and steam distribution networks.
The thermodynamic operating principle uses the difference in velocity between steam and condensate to open and close the disc, ensuring rapid discharge of condensate while preventing live steam loss. The compact screwed design with female BSPT ends allows for straightforward installation in tight spaces common in plant piping layouts.
A key advantage of the Zoloto 1055 is the integral strainer with a stainless steel (Type 304) perforated screen featuring 0.5 mm holes. This built-in filtration protects the trap internals from debris, reducing maintenance frequency and ensuring trouble-free operation in demanding industrial environments.
Key Features
- Thermodynamic disc operation for quick response and reliable condensate discharge
- Bronze body (IBR 282 Grade B) suitable for steam service
- Integral strainer with SS 304 perforated screen (Ø0.5 mm) eliminates need for separate Y-strainer
- Renewable working parts in 13% Cr stainless steel (SS 410) for extended service life
- Screwed female ends to BSPT for easy installation
- Compact design for space-constrained piping runs
- Hydrostatic shell test pressure of 35.15 kg/cm²g (500 psig)
