Drain Valve

Glass Drain Valves are precision-engineered valves designed for controlled drainage of chemical vessels, reactors, and laboratory containers.

Made from Borosilicate Glass 3.3 with PTFE seals, these valves provide chemical resistance, leak-proof operation, and durability, making them ideal for laboratory, pilot plant, and industrial-scale fluid handling.

Available in diameters from 15mm to 50mm with ground glass joint connections, these drain valves ensure safe, precise, and chemical-resistant vessel drainage.

How Glass Drain Valves Work – Step-by-Step

1. Installation – Connect valve to vessel via ground glass joint
2. Sealing – PTFE seal ensures leak-proof chemical-resistant operation
3. Drainage Control – Open or close the valve to drain fluids safely
4. Visual Monitoring – Transparent glass allows observation of fluid flow
5. Safe Operation – Borosilicate Glass 3.3 resists chemical attack and thermal stress

This ensures efficient and safe drainage in chemical, laboratory, and industrial processes.
