Transformer Drain Valve With Sample

 

 

For electrical system operators who prioritize safety, efficiency, and reliability, our Transformer Drain Valve With Sample is a purpose-built solution for coolant sampling, filling, and draining in electrical apparatus.

As a specialist in transformer and switchgear components, SUVELL didn't just design a drain valve-we built a solution to the headaches power operators deal with every day.

Forget clunky, separate sampling kits and leak-prone valves that waste your time. Our all-brass drain valve comes with a built-in sampling port, so you can draw clean, contamination-free fluid samples without breaking the system seal. No more false test results, no more messy spills, no more extra parts to haul around.

 

Pain Points

 

In practical applications of domestic industrial, marine, food, and pharmaceutical fluid systems, companies often face these challenges:

Needing to install multiple valves to achieve diversion, shutoff, and sampling, which increases pipeline complexity, procurement costs, and the risk of leaks.

Ordinary carbon steel valves are prone to corrosion in humid, salt-containing, or acid-alkaline conditions, leading to frequent repairs and replacements that disrupt production continuity.

Routine pressure testing or fluid sampling requires shutting down and disassembling pipelines, causing production downtime and efficiency losses.

Small caps on test ports are easily lost during maintenance, resulting in accessory waste and potential safety hazards from foreign objects entering the pipeline.

Value

 

This stainless steel three-way globe stop valve (with test & sampling port) is an integrated solution designed to address these local pain points:

Integrated Functionality: Combines three-way diversion, line shutoff, and pressure testing/sampling into a single valve body, greatly simplifying pipeline design.

Corrosion Resistance: Forged from 316L stainless steel, it resists acids, alkalis, and salt spray, making it ideal for highly corrosive environments such as coastal areas and chemical plants.

Non-Stop Maintenance: The built-in test & sampling port supports online pressure monitoring and fluid sampling without shutdown, ensuring continuous production.

Anti-Loss Safety Design: The test port cap is connected to the valve body via a stainless steel chain, eliminating the problem of lost accessories during maintenance.
