بررسی اجمالی محصول

راشیر چک ورق دوبلکس ویفر استیل ضد زنگ is a high-performance, compact non-return valve designed to prevent reverse flow in demanding industrial piping systems. Manufactured from premium duplex stainless steel (F51/UNS S31803 or F53/UNS S32750 super duplex), this valve provides exceptional strength, مقاومت در برابر خوردگی, and durability in aggressive environments including seawater, شیمیایی, petrochemical, and offshore applications. The wafer-style body with dual-plate (double-disc) design conforms to API 594 Type A standards, featuring short face-to-face dimensions for space-saving installation between flanges. Available in 8-inch (DN200) size with 150LB pressure rating, this valve incorporates spring-loaded plates that ensure rapid closure when flow stops or reverses, effectively protecting pumps and compressors from damaging backflow. The one-piece body construction provides excellent structural integrity, while the dual-plate design minimizes pressure drop and reduces water hammer. This valve is the trusted choice for seawater, شیمیایی, petrochemical, روغن & گاز, and marine industries.

سوالات متداول

Q1: What is the difference between F51 and F53 duplex stainless steel?

الف: F51 (UNS S31803/2205) is a standard duplex stainless steel containing 22% کروم, 5–6% nickel, و 3% مولیبدن, offering excellent strength and corrosion resistance. F53 (UNS S32750/2507) is a super duplex stainless steel containing 25% کروم, 7% نیکل, و 4% مولیبدن, with a PREN value exceeding 40; it provides superior resistance to pitting and crevice corrosion in warm seawater and high-chloride environments. F51 is sufficient for most chemical and marine applications, whereas F53 is recommended for extremely corrosive environments (such as warm seawater or high-chloride conditions).

Q2: What is the difference between a dual-plate check valve and a swing check valve?

الف: Dual-plate check valves feature two semi-circular discs mounted on a central hinge pin with torsion springs; they offer short disc travel, rapid response, a compact design, and low pressure drop. Swing check valves utilize a single-disc hinge design suitable for larger sizes and offer high flow capacity, though they close more slowly. Dual-plate check valves are better suited for space-constrained applications and those requiring rapid closure.

Q3: What is the difference between API 594 Type A and Type B?

الف: API 594 Type A check valves have a shorter face-to-face dimension and are available in wafer, lug, or double-flanged configurations with single- or dual-plate designs, making them suitable for process plants. Type B check valves have a longer face-to-face dimension and typically feature double-flanged connections. This product utilizes the Type A design.

Q4: Can this check valve be installed vertically?

الف: بله. This valve supports both horizontal and vertical installation. For vertical installation, an upward flow direction is recommended to ensure reliable disc closure assisted by gravity.

Q5: What is the opening pressure of the dual-plate check valve?

الف: The opening pressure (cracking pressure) depends on the spring stiffness and is typically low (approximately 0.5–2 psi). Please refer to the product data sheet for specific values. The spring-loaded design ensures reliable closure even at low flow rates.
