Water Source CV-125NL Check Valve, 1-1/4 in, 200 psi Pressure, Brass Body

Presenting the 1-1/4" Brass Check Valve, a robust, lead‑free component engineered for dependable flow control in both low‑pressure and high‑pressure environments. Crafted from heavy‑cast brass, this valve offers superior resistance to corrosion and is ideal for cold‑water, oil, or gas applications where reliability is paramount.

Benefits: The dual‑seal design guarantees a positive shut‑off, preventing backflow and protecting downstream equipment. Its 200 psi rating ensures consistent performance even under demanding conditions, making it a versatile choice for residential, commercial, and industrial installations.

• Heavy‑cast brass construction: Provides durability and corrosion resistance for cold water, oil, and gas systems while complying with lead‑free regulations.
• Stainless‑steel core with Buna‑N coating: Offers a resilient, non‑reactive surface that extends service life and maintains seal integrity.
• Molded cross‑lock mechanism: Prevents accidental shut‑off caused by over‑tightening, ensuring a secure, leak‑free connection.
• Integrated dual O‑rings: Engineered into the poppet so they stay in place, delivering reliable sealing at both low and high pressures.
• Progressive sealing action: The top O‑ring seals at low pressure, while both rings engage at higher pressures for an extra layer of protection.

Why Choose This Valve? Designed with precision engineering, this brass check valve delivers unmatched reliability and ease of installation. Its lead‑free composition meets strict environmental standards, and the thoughtful design elements—such as the cross‑lock and molded O‑rings—eliminate common failure points. Whether you’re upgrading a plumbing system, fitting a gas line, or ensuring oil flow consistency, this valve provides the confidence of a leak‑free, high‑performance solution.
