Is the Manually operated butterfly valve, type 1123H suitable for seawater and chemical media given its EPDM sealing and CF8M disc?

Manually operated butterfly valve, type 1123H is generally suitable for seawater and many chemical media, with the following considerations: - Materials: CF8M (stainless steel 316-grade) disc and AISI 416 stem offer good corrosion resistance; body is gray cast iron with 80 Âµm epoxy coating.suitable for seawater in many applications but less resistant than all-stainless constructions in highly aggressive or long-term marine environments. - Sealing: EPDM seat is compatible with seawater, demineralized water, alcohols and many alkalis (e.g., diluted sodium hydroxide), but EPDM is not resistant to many hydrocarbons, strong oxidizing acids, ketones, and some aggressive chemicals. - Temperature: Rated -15Â°C to +110Â°C (briefly to +130Â°C); suitability depends on media temperature staying within this range. - Pressure/connections: Available in PN6/PN10/PN16, ASA150, JIS 10K . ensure ratings match system. - Certifications: PED, PZH and Lloydâs Register indicate conformity and reliability for industrial use. Conclusion: For typical seawater service and many aqueous chemicals (including diluted alkalis and alcohols) the Manually operated butterfly valve, type 1123H is suitable. For strongly aggressive chemicals, hydrocarbons, high-temperature fluids, or continuous severe marine exposure, evaluate chemical compatibility of EPDM and cast-iron body (or consider all-stainless body and alternative elastomer like FKM/FFKM) before selection.

Can the Manually operated butterfly valve, type 1123H be fitted with a pneumatic actuator for automated control?

Yes. Manually operated butterfly valve, type 1123H can be fitted with a pneumatic actuator for automated control. The product description explicitly states it "can be manually opened and closed or operated by a pneumatic actuator." Before fitting, verify compatibility of actuator torque with valve size (especially DN200+ with lever), ensure pneumatic actuator materials and seals are chemically compatible with your media, and confirm mounting flange/drive interface and pressure/temperature limits (operating temp â15Â°C to +110Â°C, temporarily +130Â°C) meet your application.

Does the Manually operated butterfly valve, type 1123H meet PED 2014/68/EU and have required certifications for pressure systems?

Manually operated butterfly valve, type 1123H meets the PED 2014/68/EU requirements and has the required certifications for pressure systems. According to the product description, it âComplies with the requirements of the PED Directive 2014/68/EUâ and additionally holds a PZH certificate and Lloydâs Register certification, which support conformity and suitability for use in regulated pressure applications.
