The rated pressure for these valves in the DHRZO - P5 series is usually around 350 bar (35 MPa). However, it's important to confirm the exact rated pressure from the official ATOS documentation as it might be adjusted based on different configurations.
The maximum pressure that the valves can withstand for short periods is slightly higher than the rated pressure, typically around 400 bar (40 MPa), but this also needs to be verified according to the specific product details.
Response Time
These proportional valves generally have a relatively fast response time. For example, the rise time (from 0 to 90% of the rated flow or pressure) is usually within a few milliseconds, such as around 10 - 30 ms depending on the valve model and operating conditions.
The fall time (from 90% to 10% of the rated flow or pressure) also falls within a similar time range.
Electrical Characteristics
Coil Resistance: The resistance of the proportional coils varies by model. For example, it may range from 10 - 50 ohms approximately. The specific coil resistance value for each model (DHRZO - P5 - 010, etc.) can be found in the product's electrical specifications.
Rated Current: The rated current flowing through the coil is also an important parameter. It can be in the range of 0.5 - 2 A depending on the valve's design and the power requirements of the proportional control.
Supply Voltage: These valves are usually designed to work with a specific supply voltage range. Commonly, they can operate with a voltage of 24 VDC (direct current), but some models may also support other voltage options such as 12 VDC or 48 VDC. The exact voltage specification should be checked in the product data sheet.
