This two-way globe control valve assembly, model 274-03054 from Siemens' Flowrite 599 Series, is engineered for precise fluid management. The actuator used is the SKD62U, an electro-hydraulic model that incorporates a spring return for reliable operation. Designed to operate at a voltage rating of 24 Vac ±20%, this assembly is versatile under different electrical conditions. It can function effectively at an input frequency of either 50 Hz or 60 Hz.
This valve assembly has dimensions that accommodate a small but efficient design, measuring 1/2 inch (15 mm) in size. It features a flow coefficient of 1 Cv, allowing for controlled flow scenarios in diverse applications. The flow characteristic is linear, contributing to stable and predictable operation.
For control signal compatibility, this model accepts inputs ranging from 0 to 10 Vdc or 4 to 20 mA, enabling proportional control suited for various system requirements. Additionally, the valve is built with stainless steel trim for enhanced durability against wear and tear. It carries an IP54 rating, indicating solid protection against dust and water ingress, making it suitable for demanding environments. The valve can effectively function within humidity conditions of 5% to 95% RH.
