GD3 Series Tank Bottom Valve – High-Performance, Hygienic Pneumatic Seat Valve

The GD3 Tank Bottom Valve is a high-performance, pneumatically actuated seat valve engineered for critical hygienic applications that require reliable drainage and cleanability at the base of process tanks. Based on a robust and proven single-seat valve platform, this valve features a compact, space-saving design with minimal moving parts, ensuring exceptional reliability, low maintenance, and long operational life.
It is ideal for sanitary industries such as brewing, dairy, beverage processing, and pharmaceutical manufacturing, where hygienic operation and ease of service are essential. Actuated remotely via compressed air, the GD3 valve consists of a valve unit and a tank bottom flange. To enhance seal longevity and minimize wear, the seal compression is achieved through precision-engineered metal-to-metal contact.
Available in Two Flexible Configurations:
GD3-T Type – Clamp Connection
The GD3-T version features a clamp-type connection between the valve and tank flange. By slightly loosening the clamp, the valve body can be rotated to any position, enabling flexible alignment and easy maintenance access. The tank flange is directly welded to the tank, ensuring a hygienic and leak-free seal.
GD3-F Type – Bolted Connection
The GD3-F version utilizes a bolted connection, allowing for 360° rotation of the valve body for optimal positioning and installation flexibility. Like the T-type, its tank flange is permanently welded to the tank structure.
Both configurations offer dead-leg-free flow paths and full CIP/SIP compatibility and are designed to support strict sanitary process environments. The GD3 valve is a versatile, maintenance-friendly, and automation-ready solution for modern clean-in-place and drain valve applications.
