2300 Series Check Valve

Product catalog summary

Overview: The 2300 Series Check Valves are designed for high-pressure applications ranging from 0 to 10,000 psig. They feature a resilient O-ring and a single-piece design, offering benefits such as reduced susceptibility to contamination, zero leakage at normal back pressure, and automatic wear compensation.

How It Works: The valve operates by allowing flow over the poppet head with minimal turbulence when open. Upon closing, the O-ring establishes contact with a conical seat for cushioned and perfect sealing. In the closed state, the O-ring seals while the metal-to-metal seat carries full pressure, enhancing sealing efficiency with increased pressure.

Features and Benefits:

High-pressure service capability
Resilient O-ring for effective sealing
Single-piece design for durability
Zero leakage and quiet closing

Technical Data:

Body Materials: Aluminum, brass, 303 stainless steel, 17-4 PH stainless steel
O-ring Materials: Buna N, ethylene propylene, neoprene, Teflon®, Viton®
Operating Pressure: Varies by material, up to 10,000 psig for 17-4 PH stainless steel
Temperature Range: −100°F to +400°F
Connection Sizes: 1/8˝ to 1˝

End Connections and Dimensions: The document provides detailed dimensions for various pipe and tube connections, including Female/Female, Male/Male, Male/Female, and Female/Male configurations.

Ordering Information: The ordering code includes specifications for O-ring material, body material, cracking pressure, connection type, and size. Special considerations are noted for vacuum service and high-pressure applications.

Safety and Usage: It is emphasized that the system designer and user are responsible for selecting suitable products and ensuring proper installation and maintenance. Material compatibility and product ratings should be considered to prevent injury or damage.

Flow Rates: The document lists maximum flow rates (Cv values) for various valve sizes, indicating the capacity of the valves to handle different flow volumes.
