硅胶蝶阀 is a butterfly valve that uses silicone sealing material and is widely used in food, pharmaceutical, water treatment and other fields. It has the characteristics of high temperature resistance, corrosion resistance, non-toxic and odorless.
The following are key information and selection suggestions for related products:
1. Core functions and features
Silicone sealing performance: Silicone material has a wide temperature resistance range (-70 ℃~+150 ℃), suitable for high-temperature steam and corrosive media such as acids, alkalis, organic solvents, etc.
Hygiene standards: Compliant with FDA and GMP certifications, surface polished (Ra ≤ 0.4 μ m), no residual media, ensuring food grade hygiene requirements.
Structural design: For clamp, flange, or clamp connections, it supports manual, pneumatic, and electric drives, and some models come with graduated handles for precise flow adjustment.
2. Typical application scenarios
Food and beverage industry: Fluid control in the production process of dairy products, juice, etc., resistant to CIP/SIP cleaning.
Pharmaceutical industry: Aseptic formulation dispensing systems must be validated according to ASME BPE standards.
Water treatment: flow regulation in municipal water supply and sewage treatment, with optional anti sediment wear design.
3. Selection parameter reference
Suggested parameter values/option notes
Nominal diameter DN15~DN200 (commonly used) selected according to pipeline size
Pressure rating PN0.6~PN1.6MPa (conventional) High pressure scenarios require special customization
Temperature range silicone seal: -40 ℃~+150 ℃ High temperature medium needs to be replaced with fluororubber
Connection methods: quick installation (sanitary grade), flange type (industrial use), clamp type for easy quick disassembly and maintenance
4. Examples of mainstream models in the market
Manual type: such as D71X-16P stainless steel butterfly valve with silicone seal, DN50~DN100， The price range is 170~550 yuan.
Pneumatic type: As a standard electric sealed valve, driven by AC220V, with an inner diameter of 110mm, suitable for air volume regulation.
Sanitary grade: Clamp type butterfly valve, electronically polished, suitable for dairy production lines.
