Product Advantage of Silicone Rubber Butterfly Valve
*Polished CF8 Stainless Steel Body – The polished CF8 body provides good corrosion resistance and a smooth surface suitable for clean and potable water systems.
*CF8M Stainless Steel Disc – The CF8M disc offers excellent corrosion resistance and durability, making it suitable for long-term water service.
*Silicone Rubber Seat – The resilient silicone seat provides reliable sealing with good elasticity and resistance to aging under suitable water-service conditions.
*Reliable Bubble-Tight Shut-Off – The resilient seat is designed to maintain close contact with the disc and provide dependable shut-off performance.
*Suitable for Potable Water Systems – Designed for applications such as drinking water pipelines, water treatment, water supply, and clean-water distribution, subject to the applicable local drinking-water requirements.
*All-Stainless-Steel Wetted Construction – The CF8 body and CF8M disc provide a corrosion-resistant material combination for water applications where conventional carbon steel may be less suitable.
*Low Maintenance Design – The simple butterfly valve construction requires relatively little maintenance while allowing convenient installation and operation.
*Multiple Actuation Options – Available with a manual lever, gearbox, pneumatic actuator, or electric actuator according to the pipeline size and control requirements.
*Wide Application Range – Suitable for potable water, treated water, municipal water supply, water treatment plants, and other clean-water applications.

FAQ of Drinking Wafer butterfly valve
Q: What factors should be considered when selecting a butterfly valve for a patable water system?
In addition to ensuring that all components—such as the valve body, disc, and seat—meet requirements for drinking water applications, other key factors include pipe size, pressure rating, operating temperature, water quality, and connection standards. Furthermore, the valve must be suitable for the pipeline's operating conditions and disinfection treatment processes.
Q: What is the difference between a drinking water butterfly valve and a standard water butterfly valve?
While their basic structures may be similar, drinking water applications impose additional requirements regarding materials in contact with the medium, sealing materials, cleanliness, and—where applicable—regulatory certifications. Therefore, applicable certifications should be verified individually rather than relying solely on the valve's material specifications.
Q: Is this butterfly valve suitable for treated water and municipal water supply systems?
Yes. These valves are suitable for use in treated water transmission pipelines, municipal water supplies, water treatment plants, and similar potable water systems. Specific material and seal configurations should be selected based on actual water quality characteristics and operating conditions.
Q: Is a polished stainless steel surface mandatory for drinking water applications?
It is not required for every installation. Surface finish depends primarily on hygiene standards, corrosion resistance, cleaning requirements, and the specific application scenario. If there are strict requirements for internal surface smoothness, a polished finish is advantageous.
Q: How should valves be installed in drinking water pipelines?
Installation procedures are the same as for standard butterfly valves. Before installation, verify the valve size, flange standard, pressure rating, flow direction (if applicable), and available installation space. Ensure proper pipeline alignment to prevent excessive stress on the valve body and disc.
Q: How can I confirm that the valve complies with local drinking water regulations?
Drinking water regulations vary by market. Before placing an order, please specify the destination country and the required certification standards (e.g., WRAS, NSF/ANSI/CAN 61, ACS, or other local standards). This allows the supplier to confirm whether the selected materials and valve configuration meet the relevant requirements.
Q: Are you a Factory or Trading?
A: We’re a factory with 17 years production experience, OEM for some customers around the world.
Q: What is your After-sales service term?
A: 18 months for all our products.
