267-05990

The 267-05990 globe valve assembly from Siemens within the Flowrite 599 Series is engineered to control the flow of fluids effectively. This assembly has a nominal size of 2-1/2 inches and is designed to manage a variety of compatible mediums, such as saturated steam, potable water, and solutions containing antifreeze. The valve is configured as a 2-way normally-closed (N.C.) unit, ensuring that it prevents fluid flow when not energized.

With an impressive flow capacity rated at 63 Cv, the valve guarantees efficient operation suited for various industrial settings. Its flanged connections facilitate easy integration within piping systems, allowing for straightforward maintenance and replacement procedures. The valve assembly is constructed with high-quality materials; it features a bronze trim and plug, while the stem is made from durable stainless steel, providing resistance to wear and corrosion.

At the heart of this valve assembly is an integrated electro-hydraulic actuator, which provides precise control over the valve operation. The actuator uses a nominal operating voltage of 24 VAC and is designed to accept proportional control signals, allowing for flexible and responsive adjustments. These control signals can be in the form of either a voltage range of 0 to 10 Volts DC or a current range of 4 to 20 milliamps depending on the control system's specifications.

The valve stroke length measures 3/4 inches, offering sufficient movement to ensure reliable flow regulation. In terms of safety, the valve features a non-spring return (NSR) fail-safe mechanism, guaranteeing that the valve remains in its default state during power interruptions. Operating effectively within a medium temperature range from -7°C to 120°C, this valve assembly is well-suited for use in both heating and cooling applications.
