This reliable replacement thermostatic core valve tackles common issues in underfloor heating manifold isolation, such as sticking pins or faulty operation that disrupt flow control. Engineered as a direct swap for worn-out components in UFH actuators, this precision part restores smooth, responsive performance to your radiant heating system, preventing uneven warmth or system inefficiencies. Ideal for both residential and commercial setups, it ensures precise temperature regulation by allowing actuators to open and close valves seamlessly without jamming.

Key Features and Benefits

• Premium Brass Construction: Crafted from high-quality, corrosion-resistant brass for exceptional durability, longevity, and resistance to wear in demanding hydronic environments—outlasting standard replacements while maintaining leak-free integrity.
• Precision Threading for Compatibility: Features standard M30x1.5 threading to fit most common UFH actuators and manifolds, enabling a secure, hassle-free match with existing systems from major brands.
• Anti-Stick Design: Specifically designed to eliminate sticking issues caused by debris, scale buildup, or age-related wear, promoting reliable valve actuation and consistent flow for optimal heating efficiency.
• Easy Installation: Simple screw-in replacement process requires no special tools—just isolate the manifold, remove the old core, and install the new one in minutes, minimizing downtime and repair costs.
• Versatile System Integration: Compatible with water-based underfloor heating loops, supporting zoned control in multi-room setups to enhance energy savings and thermal comfort across floors.
