Containment & Transfer Systems

The Eccentric Inflatable Seal Butterfly Valve, also known as an Air-Sealed Butterfly Valve, features a unique design principle. When the valve is in the closed position, air pressure causes the valve seat to expand and press against the valve disc, creating an effective seal. When the valve opens, the compressed air is released, allowing the valve seat to retract so it no longer contacts the valve disc—eliminating friction. This design minimizes the torque required to open or close the valve and significantly extends the service life of the seal.

The Double Dosing Butterfly Valve is a high-precision discharge valve designed for accurate dosing of powders and granules. Featuring a dual-rotor system—one for fast bulk feeding and another for fine metering—it delivers both efficiency and dosing accuracy. The valve is ideal for use in automated weighing and batching systems. Its modular, hygienic, quick-clamp design allows for easy cleaning and maintenance, making it an excellent choice for food, pharmaceutical, and chemical industries.

The Powder Butterfly Valve is a compact, high-efficiency valve specifically designed for handling powdered and granular materials. It is widely used in food, pharmaceutical, chemical, plastic, and feed processing industries. Installed at the outlet of hoppers, bins, or silos, the valve operates by gravity or pneumatic control to regulate material flow. With excellent sealing performance and hygienic design, it effectively prevents dust leakage and cross-contamination. This valve is an ideal solution for safe, clean, and reliable bulk material handling.

Alpha-Beta RTP System for Contained and Aseptic Transfer
Our Alpha-Beta Rapid Transfer Port (RTP) system is designed for safe, sterile, and contamination-free material transfer in pharmaceutical isolators, cleanrooms, and containment systems. With secure alpha-beta docking and a robust interlock mechanism, it ensures aseptic transfer of products or waste without compromising the sealed environment. Compatible with stainless steel and plastic beta containers, it’s ideal for applications requiring strict GMP compliance and high-level operator safety.

High Containment Powder Valve (also known as αβ valves) are used for the closed transfer of highly active and toxic powders to prevent material leakage and protect operators and the environment. They consist of an active valve and a passive valve, which must be connected to open. After separation, each valve seals independently, achieving an OEB level of 5 for sealing performance and an OEL of < 1 µg/m³. Made of 316L stainless steel and using FDA-grade seals, they are widely used in pharmaceutical and chemical industries for API feeding and IBC transfer processes requiring strict isolation.
