Utilizing a commercial-grade brass body with 3\/4\" sweat (solder) connections, this valve is configured in the industry-standard \u003cstrong\u003eNormally Closed (N\/C)\u003c\/strong\u003e position. Driven by an advanced microcircuit-controlled gear actuator, the valve opens smoothly when energized and provides a bubble-tight seal when closed, preventing ghost flows and temperature bleed across inactive zones.\n  \u003c\/p\u003e\n\n  \u003cp style=\"margin-bottom: 12px;\"\u003e\u003cstrong style=\"font-size: 15px; color: #111;\"\u003eKey Performance \u0026amp; Installation Advantages:\u003c\/strong\u003e\u003c\/p\u003e\n  \n  \u003cul style=\"margin-top: 0; margin-bottom: 20px; padding-left: 20px;\"\u003e\n    \u003cli style=\"margin-bottom: 10px;\"\u003e\n      \u003cstrong\u003eUnmatched Close-Off Pressure:\u003c\/strong\u003e Engineered with a high-torque internal ball-valve mechanism rated for up to 125 PSI of definitive shut-off pressure.
