Stainless Steel zero dead leg CIP SIP air operated Diaphragm Valve
 
This product is a block body diaphragm valve. The valve body Zero Static Diaphragm Valve is precision-forged from 304/316L stainless steel and features an integrated forged 3-way valve block, a miniature compact valve body design, a quick-clamp connection, and a manual adjustment handwheel on top. The diaphragm is used to control media pharmaceutical diaphragm valve switching and shut-off. The flow passages have no dead corners or stagnant areas, meeting the requirements for in-line CIP cleaning and SIP steam sterilization. The valve can be used for media diversion, convergence, and switching in pipelines,zero dead leg diaphragm valve  and is widely used in high-cleanliness small process pipelines and miniature sampling lines in biopharmaceuticals, CIP SIP diaphragm valve purified water systems, food and beverage, and fine chemical/personal care applications.
 
Compared with conventional 3-way ball valves, the multi port diaphragm valve adopts a forged dead-leg-free valve body and a miniature diaphragm sealing structure, eliminating stagnant areas inside the valve cavity and enabling more thorough cleaning and sterilization. Compared with conventional 3-way diaphragm valves, this model features a miniature compact forged structure, a smaller overall size, and a reduced installation footprint, making it suitable for confined pipeline spaces and miniature sampling lines. 3-way ball valves have dead corners inside the valve cavity, making it difficult to meet the high-level sterility requirements of pharmaceutical applications. Conventional 3-way diaphragm valves have relatively large valve bodies and cannot accommodate miniature compact pipeline layouts. This forged miniature 3-way diaphragm valve features an integrally forged structure, a high level of cleanliness, and a compact, refined design, specifically developed for high-cleanliness miniature pipeline applications.

Stainless Steel zero dead leg CIP SIP air operated Diaphragm Valve
 
Feature (F)、Advantage (A)、Benefit (B)
  1. Raw Material:
  • F:Valve body: SS304 / SS316L stainless steel; diaphragm materials: EPDM, PTFE, orSilicone options.
  • A:Stainless steel provides resistance to acids and alkalis and can withstand high-temperature steam sterilization; food-grade diaphragm materials do not releasesubstances and do not contaminate the media.
  • B:Suitable for sterile and corrosive clean fluids, providing stable long-term operation and complying with FDA and 3A sanitary requirements.
  1. Manufacturing Process：
  • F: One-piece CNC forming of stainless steel forgings, precision machining of the miniature 3-way valve block, and mirror polishing of the internal and external flow passages.
  • A: The miniature flow passages are smooth and free of dead corners, with high precision at the diaphragm sealing surface for reliable sealing performance; the valve body is compact and convenient to disassemble and assemble.
  • B:  Process media are less likely to adhere and remain, reducing the risk of cross-contamination between batches and meeting the cleaning standards for sterile production in miniature clean pipelines.
  1. Structural Design：
  • F:  Integrated 3-way valve block, manual adjustment handwheel, sanitary quick-clamp connection, diaphragm sealing structure, and detachable top actuator assembly.
  • A:One valve enables switching among three media paths; the diaphragm isolatesthe media from the actuating components; the quick-clamp connection allowsconvenient disassembly and assembly and facilitates diaphragm replacement.
  • B: Reduces the number of pipeline components and leakage points, thereby lowering clean-pipeline installation costs.
  1.  Feature Advantages:
  • F:  Forged integrated miniature 3-way valve block structure, manual diaphragmactuation, sanitary mirror-polished flow passages, dead-leg-free flow passages, and
    quick-clamp connection.
  • A: The miniature valve body is suitable for confined installation spaces and enablesflexible pipeline diversion/convergence switching; the inner cavity has no stagnantareas and supports complete CIP/SIP; the diaphragm prevents the media from contacting external components.
  • B:Meets the requirements of high-standard sterile miniature pipeline processes,simplifies pipeline design in confined spaces, and reduces production risks caused by incomplete sterilization.
  1. Seal Ring Feature:
  • F:Elastic diaphragm soft sealing provides zero leakage
  • A:The diaphragm completely isolates the process media from the actuating mechanism.
  • B:The two diaphragms provide independent sealing without interfering with each other.
