Hygienic Pneumatic Drain Valves are specially designed for automatic and efficient draining of liquids from tanks, vessels, pipelines, and processing equipment in sanitary process systems and hygienic liquid handling applications. These valves ensure complete removal of residual product, condensate, and cleaning media while maintaining the highest standards of hygiene and process safety.

The valve is operated by a pneumatic actuator, providing fast, reliable, and repeatable opening and closing. This makes it ideal for automated process lines, especially in applications requiring frequent drainage during production and CIP (Clean-in-Place) / SIP (Sterilize-in-Place) cycles.

Featuring a hygienic, dead-leg-free internal design, the valve minimizes product hold-up and prevents contamination. Smooth internal surfaces allow easy cleaning and support strict sanitary requirements in critical processing environments.

Manufactured from high-grade stainless steel (SS304 / SS316 / SS316L) with a polished surface finish, hygienic pneumatic drain valves offer excellent resistance to corrosion, chemicals, and high temperatures. These valves are widely used in food, beverage, dairy, pharmaceutical, and biotech industries.
