1/2″ Metal Core Non-Return Valve | Brass Body with Steel Core – High-Pressure & High-Temp Rated

Ensure reliable flow control and system protection with this 1/2 inch (G½») metal-core valve — a robust, high-performance component designed for demanding plumbing, heating, and gas applications. Featuring a solid brass body and a stainless steel or hardened metal core (e.g., ball, spring, or seat assembly), it delivers superior durability, leak resistance, and longevity compared to plastic-core alternatives.
Ideal as a check valve (non-return valve) to prevent backflow in water, heating, or LPG lines — or as a reinforced connector/muff where extra strength is required (e.g., under floor heating manifolds, high-pressure pumps, or industrial equipment).

1/2″ Metal Core Non-Return Valve | Brass Body with Steel Core – High-Pressure & High-Temp Rated

Ensure reliable flow control and system protection with this 1/2 inch (G½») metal-core valve — a robust, high-performance component designed for demanding plumbing, heating, and gas applications. Featuring a solid brass body and a stainless steel or hardened metal core (e.g., ball, spring, or seat assembly), it delivers superior durability, leak resistance, and longevity compared to plastic-core alternatives.
Ideal as a check valve (non-return valve) to prevent backflow in water, heating, or LPG lines — or as a reinforced connector/muff where extra strength is required (e.g., under floor heating manifolds, high-pressure pumps, or industrial equipment).
Key Features:
  • 🔩 Thread Size: G½» (1/2 inch BSP) — standard for residential & commercial systems
  • 🛡️ Construction: Brass body + metal core (steel/stainless) — no plastic parts inside
  • ⚙️ Function:
    If check valve: Prevents reverse flow (backflow protection)
    If connector: High-strength coupling for critical joints
  • 🌡️ Rating: Up to 10 bar pressure, 110°C temperature (typical for brass+steel)
  • Certification: CE-marked (as shown in context) — compliant with EN standards
Why “Metal Core” Matters:
Plastic or rubber cores can deform under heat/pressure, leading to leaks or failure. A metal core ensures consistent sealing, even in harsh conditions — essential for boilers, heat pumps, solar thermal systems, and gas installations.
Applications:
• Water supply lines (preventing backflow into mains)
• Heating circuits (protecting circulator pumps)
• Gas lines (where approved for use)
• Industrial equipment & irrigation systems
