Swagelok SS-8CP2-1/3 is a 1-piece poppet check valve designed for reliable backflow control in both general-purpose industrial systems and high-purity applications. This compact valve is constructed from 316 stainless steel and features 1/2 inch male NPT connections at both ends. It is equipped with a fluorocarbon FKM O-ring and a fixed cracking pressure of 1/3 psig (0.03 bar). The valve provides a maximum flow coefficient (Cv) of 1.2 and maintains a pressure rating of 3000 PSIG at 100°F (206 BAR at 37°C).

Features and Usage

Swagelok poppet check valves are engineered to control backflow effectively. The 1-piece design offers a streamlined profile suitable for installations with limited space.

Application Suitability

Ideal for preventing reverse flow in liquid or gas systems where a fixed cracking pressure and reliable sealing are required. The SC-10 cleaning process makes it suitable for many high-purity environments.

System Design Responsibility

To ensure safe and trouble-free performance, the system designer and user must consider the total system design, including material compatibility, adequate ratings, and proper installation and maintenance.

Product Integration

Do not mix or interchange Swagelok products or components with those of other manufacturers to maintain system integrity and safety standards.
