274-03006

The 274-03006 globe valve assembly from Siemens is designed specifically for managing the flow of various mediums including saturated steam and water mixtures, as well as water with antifreeze. This unit has a nominal valve size of 1-1/4 inches, making it suitable for diverse applications where consistent flow control is essential. Its port configuration is set as a 2-way normally-open (N.O.) structure, facilitating constant access for fluid passage when the actuator is inactive.

Efficiently engineered, this valve features a flow capacity rated at 16 Cv, which signifies its effectiveness in handling medium flow. The integrated electro-hydraulic actuator plays a crucial role in achieving optimal performance while delivering the necessary actuation. A notable aspect of this design is its fail-safe mechanism, which employs a spring return (SR), ensuring the valve returns to a safe position during power loss.

The valve has a stroke length of 3/4 inches, which determines the extent of movement that directly influences fluid flow regulation. Additionally, it exhibits a linear flow characteristic, promoting smooth adjustment across varying flow conditions. The actuator operates within a nominal voltage of 24 VAC, connecting seamlessly through internal thread connections at both ends.

Control input to the valve assembly is managed through a proportional signal, accommodating either 0 to 10 volts DC or a 4 to 20 milliamps input. This allows for precise flow management tailored to application needs. The valve assembly effectively functions within a medium temperature range from -7°C to 120°C, ensuring that it can withstand fluctuating temperatures in various operational setups. Constructed with stainless steel trim, it guarantees durability and resistance to corrosive elements while consuming a power level of 18 VA.
