Glass Valves

Glass Valves | 6600 Series

Glass Valves are specially designed for safe and precise control of highly corrosive and hazardous chemicals, particularly in applications where visual monitoring of flow is critical. Manufactured using Borosilicate Glass Type 3.3, these valves offer excellent chemical resistance, thermal stability, and long service life.
The transparent valve body allows operators to visually observe flow conditions, detect crystallization, scaling, blockages, or abnormal flow patterns, and take corrective action before process failure occurs. Glass valves are widely used in pickling plants, acid regeneration systems, chemical processing units, and reactor feed lines, where handling strong acids and aggressive media is routine. Glass valves are constructed with a borosilicate glass body combined with PTFE internal components, ensuring superior resistance to corrosion and chemical attack. The smooth internal surface prevents media build-up and enables easy flushing and cleaning.
The valve design supports ON–OFF as well as modulating control, making it suitable for both isolation and flow regulation duties in critical chemical processes.

Design & Construction:

Glass valves are constructed with a borosilicate glass body combined with PTFE internal components, ensuring superior resistance to corrosion and chemical attack. The transparent body enables visual monitoring while the smooth internal surface prevents media build-up and allows easy flushing and cleaning.

Working Principle:

Working Principle
The valve operates by lifting or positioning a PTFE plug within the transparent glass body
Open Position
Allows free flow of chemical media
Modulating Position
Plug adjusts gradually for accurate flow control
Closed Position
Plug seats tightly to prevent leakage
The clear glass body enables real-time visual inspection, ensuring safe and controlled operation in corrosive service.

Automation & Control Options:

  • Control Modes: On/Off, Modulating (4–20 mA / 0–10 V)
  • Actuator Options: Single Phase, Three Phase, IP-rated (Weatherproof)
  • Feedback Systems: Position Transmitter, Potentiometer
  • Communication: PLC / DCS Integration (Analog & Digital Signals)
  • Control Interface: Local Control Panel (LCP), Remote Operation
