Overview

Sanitary grade electric diaphragm valve is an automated fluid control equipment designed specifically for high hygiene standard industries, widely used in fields such as food and beverage, pharmaceuticals, biotechnology, cosmetics, etc. that require strict cleanliness. Its core feature is to use an electric actuator to drive the elastic diaphragm to achieve opening and closing, ensuring that the fluid is isolated from the metal components inside the valve, eliminating the risk of contamination, and meeting the process requirements of sterility and easy cleaning.

Product Details

1、 Product Overview

Hygienic gradeElectric diaphragm valveIt is an automated fluid control device designed specifically for industries with high hygiene standards, widely used in fields such as food and beverage, pharmaceuticals, biotechnology, cosmetics, etc. that require strict cleanliness. Its core feature is to use an electric actuator to drive the elastic diaphragm to achieve opening and closing, ensuring that the fluid is isolated from the metal components inside the valve, eliminating the risk of contamination, and meeting the process requirements of sterility and easy cleaning.

2、 Structural characteristics

Sanitary grade design

　　Electric diaphragm valveThe valve body is made of 316L stainless steel or electropolished material, with an inner surface Ra ≤ 0.8 μ m, in compliance with international hygiene standards such as 3A, SMS, DIN, etc.

Seamless and retention free structure, avoiding microbial growth, supporting CIP/SIP online cleaning and sterilization.

Diaphragm technology

The diaphragm material is EPDM, PTFE or silicone rubber, which is corrosion-resistant and heat-resistant (up to 130 ℃ or above), suitable for acid and alkali, organic solvents and high-purity media.

As a component in contact with the medium, the diaphragm can be quickly replaced and maintained easily.

Electric actuator

Equipped with high-precision servo motors or stepper motors, supporting 4-20mA signals, Modbus communication or PLC linkage control, to achieve precise flow adjustment.

IP65/IP67 protection level, suitable for humid or clean room environments.

3、 Working principle

After receiving the control signal, the electric actuator pushes the valve stem up and down, causing the diaphragm to deform:

Open state: The diaphragm is detached from the valve body flow channel, and the medium is unobstructed.

Closed state: The diaphragm tightly presses against the valve seat, forming a seal and achieving zero leakage (leakage level up to VI).

4、 Core advantages

Zero cross contamination: The isolation medium and mechanical components comply with FDA and GMP certification requirements.

Low shear force: suitable for sensitive fluids (such as juice, vaccines, dairy products) to avoid component damage.

Energy saving and efficient: Electric drive saves more than 30% energy compared to pneumatic drive, with noise levels below 60dB.

Intelligent integration: supports remote monitoring, fault alarm, and data recording, adapted to Industry 4.0 systems.

5、 Typical application scenarios

Pharmaceutical industry: sterile formulation pipelines, bioreactor feeding.

Food and beverage: CIP circuit, filling line, syrup conveying.

Semiconductors: Ultra pure water, chemical distribution system.

6、 Selection Guide

Users need to choose the appropriate model based on the characteristics of the medium (temperature, pH value), flow rate (DN15-DN150), pressure (normal pressure to 10 Bar), and certification requirements (such as EHEDG, ASME BPE), and provide customized options (such as quick fit clamps, threaded connections).

7、 Maintenance and upkeep

Regularly check the aging condition of the diaphragm (it is recommended to replace it every 12 months).

Sharp tools are prohibited during cleaning, and neutral cleaning agents are recommended.

The actuator should avoid dust accumulation and use food grade grease for lubrication.
