Diaphragm valves

超过30年，ASEPCO一直在为无菌处理开发最优质的隔膜阀。

We are trusted by bioprocessing engineers worldwide for developing stainless steel valve products that deliver cost savings, accelerate process and maintenance times—while reducing the risk of contamination.

Today we manufacture the aseptic processing industry’s diaphragm valve of choice.

• No tools or special training required
• 集成，不可调节的旅行停止
• No dead legs or dead spaces
• 冲洗贴装设计和简单的夹具组件

隔膜密封独立于寿lder seal (the seal between the inside and outside of the valve). Using a manual or pneumatic actuator, you can easily open and close the seal. The cylindrical shape of the diaphragm, when squeezed into the sealing position, holds the seal—tested to an internal water pressure of up to 20 bar (varies depending on diaphragm material and actuator type) without leakage.

When the valve is closed, the unique CIP/SIP “behind-the-seat flow path” can be created if you add a CIP or SIP port. This flow path makes it easy to steam or clean the valve while the valve is closed. This allows for validated aseptic and sterile system connections and transfers to be performed. Combined these features save time and money by reducing maintenance time, improving performance with a less restrictive flow path.

The design of the basic weir-style diaphragm valve seal presents a number of issues for process engineers working in the biotechnology and pharmaceutical industry.

In typical configurations, a weir in the valve body rises in a fluid path and when the valve is closed, the diaphragm meets the weir to shut off the flow.

While a simple technology intended to reduce turbulence and shear, weir-style valves present a number of issues, for example in upstream processing applications they can be difficult to install, prone to leaks, and increase the potential of product contamination.

在传统的堰阀中，通过将隔膜放置在阀体和致动器的配合面之间进行密封。然后将该组件与一组螺母和螺栓一起保持在一起。由于其出色的化学相容性出色的耐腐蚀性在暴露于重复的清理（CIP）和蒸汽的情况下，阀体由不锈钢制成。

• Fully traceable materialsValves are made from fully traceable materials, regardless of the type of alloy you choose, ensuring they meet your local standards and codes.
• Long-lasting surface finish它们是完全加工，电力研制和钝化的标准，为您提供一致，持久的表面光洁度。
• Saves you time and moneyOur valves are designed to save you time and money. Changing a diaphragm only takes seconds, making your valves simple to inspect, clean and use
• 你可以依赖的品质We inspect every valve - not just a representative sample. Each valve has passed stringent quality tests at every stage of production.
