Shanghai Zhibang Valve Manufacture Co., Ltd., a professional manufacturer established in 2016 with an annual export value of US$1–1.5 million, is proud to present our Wafer Type Dual Plate Check Valve DN150 ANSI 150, specifically engineered for cooling water systems. This valve combines a compact wafer design with high-performance dual plates, ensuring reliable backflow prevention, minimal pressure drop, and easy installation between flanges. Backed by our ISO9001-certified quality management system, it delivers consistent performance in demanding industrial applications.
Our dual plate check valve is designed to meet the rigorous requirements of cooling water circuits, where efficient flow control and corrosion resistance are critical. The wafer-type body allows for a lightweight, space-saving solution that reduces installation costs and simplifies maintenance. With a robust construction and optional seat materials, this valve offers long service life even in continuous operation.
Product Features
- Wafer Type Design – Compact and lightweight, fits between standard ANSI flanges, reducing footprint and installation time.
- Dual Plate Mechanism – Two spring-loaded plates close quickly upon flow reversal, minimizing water hammer and ensuring positive sealing.
- Low Pressure Drop – Streamlined flow path and large opening area keep energy loss low, ideal for cooling water systems with high flow rates.
- Corrosion-Resistant Materials – Available body materials include cast iron, ductile iron, and stainless steel; disc and seat options (NBR, EPDM, Viton) suit various water qualities and temperatures.
- ANSI 150 Rated – Designed for a pressure rating of 150 psi at ambient temperature, suitable for most cooling water applications.
- Automatic Operation – No external actuator required; the valve operates fully automatically based on flow direction.
- Easy Maintenance – Simple design with few moving parts facilitates quick inspection and replacement of seat rings.

Frequently Asked Questions (FAQ)
-
Q: What is the purpose of a dual plate check valve in a cooling water system?
A: It prevents backflow of water when the pump stops, protecting the system from reverse flow damage and reducing water hammer effects. -
Q: Can this valve be used for vertical or horizontal piping?
A: Yes, the wafer type dual plate check valve can be installed in both horizontal and vertical pipelines, provided the flow direction is upward in vertical installations. -
Q: What seat material is best for cooling water with high chlorine content?
A: For chlorinated water, we recommend EPDM or Viton seats, as they offer excellent chemical resistance. Please consult our technical team for specific recommendations. -
Q: Is the valve suitable for seawater cooling systems?
A: Yes, with appropriate material selection (e.g., stainless steel body and disc, super duplex optional), it can be used in seawater applications. Contact us for customized solutions. -
Q: What is the standard face-to-face dimension for this DN150 ANSI 150 valve?
A: The face-to-face length follows API 594 short pattern, which is typically 140 mm (5.51 inches) for DN150. Please verify with our engineering drawing. -
Q: Do you provide test certificates and material reports?
A: Yes, we can provide mill test certificates, hydrostatic test reports, and material certifications upon request as part of our quality documentation. -
Q: How does the wafer type valve seal between flanges?
A: The valve body has concentric grooves that accommodate gaskets or O-rings (optional) to ensure a leak-tight seal when bolted between ANSI flanges. -
Q: What is the lead time for this valve?
A: Standard lead time is 15–25 working days, depending on order quantity and material availability. Rush orders can be accommodated with prior arrangement.
