Product Overview

の ANSIクラス 300 フランジ型スイングチェックバルブ is a high-performance, automatic backflow prevention device designed for reliable one-way flow control in water, 油, ガス, および産業用配管システム. Featuring a stainless steel (SS304 / SS316) body and a swing-type disc mechanism, this valve allows forward flow to open the disc and automatically closes when flow reverses or stops, preventing backflow and protecting pumps, コンプレッサー, and other equipment from damage. The flanged ends conform to ANSI Class 300, JIS, and PN standards, ensuring compatibility with international piping systems. Available in sizes from DN40 to DN600 (1.5″ to 24″) with multiple material options — including WCB carbon steel, ステンレス鋼 (SS304/SS316), and alloy steel — this valve is suitable for a wide range of industrial applications. With ISO, EAC, WRAS, and CE certifications, it meets global quality and safety standards. The valve is available with manual, worm gear, pneumatic, hydraulic, or electric actuation options.

FAQ

Q1: What is the difference between a swing check valve and a dual-plate check valve?

あ: Swing check valves feature a single-disc hinged design; they are suitable for medium-to-large bore sizes, offering high flow capacity and low pressure drop, though their closing speed is relatively slow. Dual-plate check valves utilize two spring-assisted discs, resulting in faster response times, shorter installation lengths, and lighter weight; they are ideal for larger sizes and space-constrained applications.

第2四半期: Which pressure standards does this valve meet?

あ: This valve is available in various pressure ratings, including ANSI Class 150–900, JIS 10–20K, and PN 1.0–32.0 MPa. The standard model is ANSI Class 300. Please specify your required pressure rating when placing an order.

Q3: Can the valve body be upgraded to SS316L or alloy steel?

あ: はい. We offer material upgrade options such as SS316L, duplex stainless steel, and alloy steel, suitable for highly corrosive media, high-temperature/high-pressure environments, or special operating conditions. Please specify your requirements when placing an order.

Q4: What is the difference between EPDM and PTFE sealing materials?

あ: EPDM (Ethylene Propylene Diene Monomer) is suitable for water and mild chemicals, with a temperature range of -20°C to +120°C and excellent sealing performance. PTFE (Polytetrafluoroethylene) offers superior chemical resistance and a wider temperature range (up to +230°C), making it suitable for corrosive media and high-temperature applications.

Q5: Can third-party inspection reports be provided?

あ: はい. We can provide material testing reports, pressure test reports, and non-destructive testing (NDT) reports issued by third-party inspection agencies. Please specify this requirement when requesting a quote.
