The Siemens 172E-10328 ball valve features robust control with its 2-inch size, providing reliable operation with a flow coefficient (Cv) of 63. Constructed with a chrome-plated brass ball and brass stem, this valve ensures durability. Designed for 2-way flow direction, the valve includes a fail-safe actuator, GMA121.1P, which functions in a normally closed (NC) position, offering a secure shutoff with a 200 psi close-off pressure.
This assembly is ideal for professional HVAC installations, particularly suitable for systems requiring precise flow control and robust operation.
