Premium 1/4" NPT 2-Piece Full Port 316 Stainless Steel Ball Valve (SSR-25)
The PneumaticPlus SSR-25 is a high-performance 1/4" NPT Female x Female Ball Valve constructed entirely from 316 Stainless Steel (CF8M). Engineered for the most demanding corrosive environments and high-pressure industrial applications, it features a 1000 PSI CWP rating and a Full Port design for unrestricted flow. Equipped with an integrated ISO mounting pad, the SSR-25 is the ultimate choice for chemical processing, marine service, and automated industrial systems.
The Professional Standard for Corrosive & High-Pressure Service
The SSR-25 is the "Top-Tier" shut-off solution when system longevity and chemical compatibility are the primary requirements:
- Chemical & Petrochemical Processing: 316 Stainless Steel provides superior resistance to chlorides and harsh chemicals that would cause "dezincification" or pitting in standard brass valves.
- Marine & Saltwater Environments: Built to withstand salt spray and corrosive coastal atmospheres without seizing or degrading.
- High-Pressure Industrial Pneumatics: Rated for 1000 PSI CWP, offering a substantial safety overhead for heavy-duty industrial air, water, and oil (WOG) systems.
- Automated Systems & Actuation: Features an integrated 10-24 UNC threaded mounting pad, allowing for the direct installation of pneumatic or electric actuators without custom brackets.

Premium Design & Safety Features
- 316 Stainless Steel Superiority: Contains molybdenum for enhanced resistance to pitting and crevice corrosion compared to 304 stainless steel.
- Investment Cast 2-Piece Body: High-precision casting reduces the number of leak paths while maintaining a slim profile for tight installations.
- Bubble-Tight PTFE Sealing: High-grade PTFE (Teflon) seats and packing ensure a reliable seal across a wide temperature and pressure spectrum.
- Lockable Lever Handle: 304 Stainless Steel handle with a high-visibility vinyl grip and a locking mechanism for added system safety.
Frequently Asked Questions
Q: When should I choose the SSR-25 over a brass valve like the FBB-25?
A: The SSR-25 should be selected if your system involves corrosive chemicals, saltwater, or requires a pressure rating above 600 PSI. While brass is ideal for standard air lines, 316 Stainless Steel is a "lifetime" upgrade for harsh industrial environments.
Q: What is the purpose of the ISO mounting pad on this valve?
A: The mounting pad allows you to attach a pneumatic or electric actuator to the valve. This makes it possible to automate your flow control system without needing expensive, custom-fabricated brackets.
Q: Can the SSR-25 be used for high-temperature steam applications?
A: Yes. It is rated for 150 PSI WSP (Working Steam Pressure) and can operate in temperatures up to 425°F, far exceeding the capabilities of standard brass valves.
