( Brand: Mac Valves Inc ), ( Manufacturer Part Number: 111B-110JB ), ( Part Type: Manifold )
The **MAC Valves 111B-110JB (and 111B110JB)** series represents a precision-engineered line of **high-performance, multi-function ball valves** designed for demanding industrial, commercial, and residential plumbing applications where reliability, durability, and ease of installation are paramount. These valves are part of MAC Valves **110 Series**, a robust collection of **full-port, brass-body ball valves** engineered to deliver superior flow efficiency, corrosion resistance, and long-term performance in a wide range of fluid handling systems. The **111B-110JB** variant, in particular, features a **1/2-inch (15mm) nominal size** with a **110JB stem configuration**, which includes a **handwheel with a 110-degree rotation stop** a distinctive design that ensures the valve cannot be accidentally over-torqued, preventing damage to the internal components while maintaining a secure seal. Constructed from **yellow brass (C37700, also known as Muntz metal)**, these valves offer an excellent balance of strength, corrosion resistance, and thermal conductivity, making them ideal for applications involving water, gas, steam, and light oils. The **full-port design** ensures minimal pressure drop and optimal flow rate, while the **PTFE (Teflon) seat** provides a tight, leak-proof seal that resists wear and chemical degradation over time. The **110JB stem** incorporates a **screw-in design with a threaded connection**, allowing for easy installation and maintenance without the need for specialized tools, though a wrench may be required for tightening. The **handwheel** is machined from durable metal and features a **smooth, ergonomic grip**, reducing operator fatigue during frequent adjustments. Additionally, the valve s **pressure rating of 200 PSI (14 bar)** at temperatures up to **212 F (100 C)** makes it suitable for standard residential plumbing, HVAC systems, irrigation networks, and light industrial processes where moderate pressure and temperature conditions are encountered. For added convenience, the **111B-110JB** is available with optional **threaded or soldered connections**, providing versatility in installation methods depending on the specific piping system requirements. Whether used in new construction, retrofits, or maintenance applications, these valves exemplify MAC Valves commitment to **durability, precision, and user-friendly design**, ensuring dependable performance for years with minimal upkeep.
