14 Inch 150LB C95800 Dual Plate Wafer Check Valve: Complete Guide for Industrial Applications

Introduction: What Is a Dual Plate Wafer Check Valve?

A Dual Plate Wafer Check Valve is a compact, high-performance non-return valve designed to prevent reverse flow in piping systems. Unlike traditional swing check valves, the dual plate design uses two spring-loaded plates that open with forward flow and close quickly when flow stops, reducing water hammer and improving system reliability.

A Double Door Check Valve, also known as a Dual Plate Check Valve or Wafer Check Valve, is widely used in industrial applications where space, efficiency, and long-term durability are critical.

Among various sizes and pressure ratings, the 14 Inch 150LB Dual Plate Wafer Check Valve is a popular choice for large-scale pipeline systems, especially in water treatment, marine, oil & gas, power generation, and chemical processing industries.

STV Valves provides reliable wafer check valve solutions with advanced manufacturing technology, high-quality materials, and customized options to meet demanding industrial requirements.

What Is a 14 Inch 150LB Dual Plate Wafer Check Valve?

A 14 Inch 150LB Dual Plate Wafer Check Valve is a wafer-style check valve designed for pipelines with a nominal diameter of 14 inches and an ASME Class 150 pressure rating.

The valve is installed between pipe flanges and uses a slim wafer body design, which makes it lighter and more economical compared with conventional flanged check valves.

The main components include:

• Valve body
• Two semi-circular plates (double doors)
• Spring assembly
• Hinge pin
• Seat sealing system
• Retaining components

When fluid moves in the correct direction, the two plates open simultaneously. When the flow decreases or reverses, the spring-assisted plates quickly close to protect pumps, compressors, and pipelines.
