D81X Sanitary Butterfly ValveOverview

Overview

The D81X sanitary butterfly valve is a sterile special control valve developed for clean fluid working conditions. Driven manually, the handle drives the butterfly plate to rotate 90 degrees to realize rapid opening, closing and cut-off control of media in clean pipelines. Adopting a standard sanitary quick-clamp connection structure, the valve is easy to disassemble and install with strong adaptability. The valve body is integrally made of 304 and 316L food-grade stainless steel, and the flow channel is polished with high-precision mirror finish, featuring smooth inner wall, no dead corners and no residual gaps. Equipped with food-grade special seals, the overall structure complies with GMP clean production standards and supports CIP online cleaning and SIP high-temperature sterilization processes. It is widely used in fluid pipeline systems with strict requirements for medium cleanliness and sterility in pharmaceutical, food and beverage, dairy, bioengineering, pure water, fine daily chemical and other industries.

                                   

D81X Sanitary Butterfly ValveCharacteristic

Features

1. High-cleanliness and sterile structural design

The valve body is forged from 304/316L medical and food-grade stainless steel. The inner and outer flow channels are mirror-polished with high surface smoothness, no pores or concave dead corners. It effectively avoids medium residue, bacterial growth and microbial contamination, fully meeting the sterile operation standards of clean production industries.

2. Sanitary quick-clamp connection for easy maintenance

Adopting the industry-standard quick-clamp structure, the valve can be quickly disassembled, inspected and replaced without dismantling the pipeline, greatly reducing equipment downtime and adapting to the frequent cleaning, disinfection and maintenance requirements of clean production lines.

3. Food-grade safe sealing with zero precipitation and pollution

Fitted with food-grade EPDM and silicone seals, which are non-toxic, odorless, free of harmful precipitation, hydrolysis-resistant, high-temperature resistant and aging-resistant. Compatible with various clean media, the seals fit tightly and evenly to achieve stable zero leakage and prevent medium leakage and cross-contamination.

4. Full-bore streamlined flow channel without medium retention

Adopting an equal-diameter straight-through streamlined structure with optimized butterfly plate design, the flow channel is smooth and unobstructed with minimal fluid resistance. No medium retention or precipitation occurs during transmission, effectively ensuring the quality stability of clean media such as medicinal liquid, beverages and pure water.

5. Compatible with full-range CIP/SIP cleaning and sterilization

The integrated structure without splicing gaps and material accumulation grooves can resist the erosion of acid-base cleaning solutions and high-temperature steam sterilization. It adapts to the in-situ online cleaning and high-temperature sterilization processes of production lines and meets the requirements of continuous sterile production.

6. Sensitive and flexible operation with precise and stable control

Adopting a direct-connected manual transmission structure with simple and efficient transmission, 90-degree rotation can complete full opening and closing. The valve operates smoothly without jamming and labor-saving, realizing accurate pipeline on-off control and adapting to frequent start-stop working conditions of various clean pipelines.

7. Corrosion-resistant material with long service life

The integral stainless steel material has excellent resistance to moisture, weak acid and alkali, and medium oxidation, suitable for humid and clean production environments. The seals feature outstanding aging resistance and fatigue resistance, ensuring stable long-term operation, low failure rate and long service life.

8. Compact and lightweight structure with wide adaptability

Featuring simple and compact overall structure, small size and light weight, the valve occupies little installation space and can flexibly adapt to various dense clean pipeline layouts. It is widely applicable to clean fluid control systems in medicine, food, biology, pure water and other fields.
