The 274-03075 model from Siemens' Flowrite 599 Series is engineered as a two-way globe control valve assembly. This unit utilizes the SKD62U actuator, which features an electro-hydraulic design with a spring return mechanism for dependable operation. Rated for 24 Vac with a tolerance of ±20%, this valve operates efficiently across common input voltage frequencies of 50 and 60 Hz.
Constructed with stainless steel trim, the assembly ensures durability in various conditions. It has an IP54 rating, providing protection against dust and water ingress. The valve measures 1/2 inch (15 mm) in size and boasts a flow coefficient of 4 Cv, making it suitable for numerous fluid control applications.
The humidity rating ranges from a minimum of 5% to a maximum of 95% RH, allowing the valve to function reliably in environments with varying moisture levels. Further enhancing its versatility, the control signal can accept inputs of 0 to 10 Vdc or 4 to 20 mA, enabling proportional control for linear flow behavior. This valve assembly is ideal for scenarios requiring precision in fluid management.
