Pneumatic glass-lined flush bottom valve

This pneumatic diaphragm glass-lined discharge valve integrates automatic control with extreme chemical resistance. Engineered for the critical bottom outlet of chemical reactors and vessels, the valve combines a heavy-duty pneumatic diaphragm actuator and an emergency manual handwheel. Its thick glass-enameled lining protects the contact surfaces from aggressive chemical corrosion while offering a smooth, non-stick surface for viscous or crystalline media.
