Lined Bottom Drain Valves BAV

Product catalog summary

Overview: The document provides detailed specifications and features of Richter's bottom drain valves, specifically the BAV and BAVM models. These valves are designed for high corrosion resistance and hermetic sealing, suitable for aggressive and ultrapure liquids.

Specifications:

Lining: Pure PTFE, optionally antistatic, with a thickness of 5-6 mm (0.2 to 0.25 inch), FDA-compliant.
Body: Made of ductile cast iron EN-JS 1049 (≈ ASTM A395), featuring a self-draining outlet nozzle.
Sealing: PTFE bellows for hermetic sealing, standard up to 10 bar (145 psi).
Temperature Range: -60 to 180 °C (-75 to 360 °F) depending on the model.
Pressure Range: 0.1 mbar (0.001 psi) vacuum to 10 bar (145 psi).

Features:

Compliant with the German Clean Air Act (TA-Luft).
Gas-tight with leakage rate A according to DIN EN 12266.
Available with manual or remote actuation (BAV/… for manual, BAVM/… for remote).
External corrosion protection with epoxy-coated body and stainless steel components.

Applications: Suitable for use under PTFE- or glass-lined vessels, or those made of materials like Hastelloy® or titanium. The design allows the plug to penetrate light sedimentation and incrustations.

Dimensions and Materials:

Available in sizes DN 80/50 (3"/2"), DN 100/80 (4"/3"), and DN 150/100 (6"/4").
Components made from materials such as ductile cast iron, PTFE, stainless steel, and PFA.

Additional Information: The document includes diagrams and tables detailing dimensions, weights, and materials used for various parts of the valves.

Richter bottom drain valves Fields of application Richter bottom drain valves are highly corrosion-resistant and hermetically sealed. They are particularly suitable for applications i nvolving highly aggressive and ultrapure liquids, installed under PTFE- or glass-lined vessels or such made of e.g. Hastelloy®, titanium etc. The plug opens into the vessel and can therefore penetrate light sedimentation and incrustations. BAV/BAVM bottom drain valves have universal chemical resistance and have a cost and lead time advantage over to valves made of special metals. Operating range • -60 to 180 °C...
