Borosilicate Glass Straight Through Valves
Goel Glass manufactures industrial Straight Through Valves for uninterrupted, linear flow regulation in glass process piping. The straight-through internal bore design minimizes hydraulic flow turbulence, decreases pressure loss, and allows unrestricted product flow between process vessels, heat exchangers, and distillation columns.
Operating fluid is contained strictly within the borosilicate glass body and PTFE sealing elements, providing exceptional service life even with boiling acids and aggressive chemical reagents.

Spindles are made of PTFE.
Key Features
- 90-Degree Angular Geometry: Minimizes piping elbows and dead volume at pipeline turns.
- Wetted Parts: High-purity Borosilicate Glass and virgin PTFE only—immune to corrosive acids, halogens, and organic solvents.
- Full Vacuum Endurance: Certified for high-vacuum distillation systems down to -1 bar.
- Visual Verification: Annealed transparent body allows immediate visual detection of crystallization, plugging, or valve leakage.
Applications
Widely used in pilot plants, fine chemical synthesis, pharmaceutical reactors, and corrosive liquid transfer manifolds across Canada and the United States.
