The **MAC Valves 82A-MC-000-TM-DAAP-1DA** is a high-performance, precision-engineered **ball valve** designed for demanding industrial applications where reliability, durability, and leak-proof performance are critical. This valve belongs to the **MAC Valves 82A series**, a robust line of manual and automated ball valves engineered for use in harsh environments, including oil and gas, chemical processing, water treatment, and marine systems. The **82A-MC-000-TM** variant features a **full-port, floating ball design**, ensuring maximum flow capacity and minimal pressure drop while maintaining tight shutoff capabilities. The **DAAP** designation indicates that this valve is equipped with a **direct-acting pneumatic actuator**, providing precise and consistent operation under varying pressure and temperature conditions. This actuator is designed for **fail-safe operation**, meaning it can be configured to default to either a fully open or fully closed position in the event of air supply failure, enhancing system safety.
The valve body is constructed from **cast carbon steel (ASTM A216 WCB)**, a material known for its strength, corrosion resistance, and ability to withstand high-pressure applications, making it suitable for temperatures ranging from **-29 C to 204 C (-20 F to 400 F)**. For applications requiring enhanced corrosion resistance, the valve can be furnished with **stainless steel (ASTM A105 or A351 CF8M)** components, ensuring longevity in aggressive chemical environments. The **1DA** designation signifies that this valve is equipped with a **double-acting pneumatic actuator**, allowing for both opening and closing operations via pneumatic control, which is ideal for automated systems where rapid response and precise positioning are essential.
The **82A-MC-000-TM-DAAP-1DA** is designed with a **lug-style end connection**, featuring **NPS 2 (DN 50)** flanges that comply with **ANSI B16.5** standards, ensuring compatibility with standard piping systems. The valve s **full-port design** minimizes turbulence and reduces erosion, making it particularly well-suited for high-flow applications such as crude oil, natural gas, and water distribution. The **floating ball mechanism** provides a tight seal when closed, while the **pneumatic actuator** delivers smooth and reliable operation, reducing wear and tear on the valve s internal components. Additionally, the valve is equipped with **position feedback mechanisms**, allowing for real-time monitoring of its status, which is invaluable in automated control systems.
For enhanced safety and ease of maintenance, the **82A-MC-000-TM-DAAP-1DA** features a **quick-release bonnet design**, enabling rapid disassembly for inspection, repair, or replacement of the ball and seat without requiring specialized tools. The valve s **seal materials**, typically made from **PTFE, NBR, or Viton**, are engineered to resist abrasion, chemicals, and temperature fluctuations, ensuring long-term performance even in the most demanding conditions. The **pneumatic actuator** is compatible with standard **100 150 psi (6.9 10.3 bar) air supply**, offering flexibility in integration with existing control systems. Whether deployed in **offshore platforms, refineries, chemical plants, or municipal water treatment facilities**, this valve delivers the combination of **durability, precision, and operational reliability** that industrial operators demand.
