It is an electro-hydraulic pressure regulating control valve used to position single acting steam turbine valve servers/actuators. It converts the 4-20mA DC input current signal into a proportional output pressure signal, which can accurately control the oil pressure and achieve precise positioning of steam turbine valves. It is widely used in process control systems, industrial automation, pneumatic execution systems, etc.
Description
Technical Parameter
Input signal: 4-20mA DC current signal.
Pressure range: The typical working pressure range is 0 to 10 bar (14.5 to 145 psi), and there are also other optional pressure range versions such as 25 bar.
Work environment: Can be used in hazardous areas such as Zone 1 and Zone 2, and can adapt to a certain degree of oil pollution environment (ISO 20/16).
function characteristics
High precision and fast response: With high precision, it can achieve precise valve positioning, quickly respond to changes in input signals, and have good effects on the speed and load control of steam turbines, helping to improve system performance and reduce mechanical wear.
Redundant design: Suitable for critical applications, equipped with redundant inputs/sensors, capable of receiving signals from redundant controllers, with redundant (dual) CPC (master/slave) functionality, improving system reliability and availability.
Status monitoring: Provides status and health indicators, including pressure sensor health, input demand signal health, internal unit health, input power quality, and other information, and can control pressure readings to facilitate users’ understanding of equipment operation status, maintenance, and troubleshooting.
Durable and sturdy: Made of corrosion-resistant materials and a sturdy actuator design, its self-cleaning valve algorithm and specially designed ports can adapt to harsh working environments, ensuring stable operation even under oil contamination or other challenging conditions.
Compliant with standards: Compliant with applicable CE directives such as ATEX, mechanical, PED, and EMC standards, certified for hazardous locations in North America, and safe for use in various industrial environments.
Dimensions and weight: The dimensions are approximately 14W x 11H x 4D inches, and the weight is approximately 9.11 lbs or 25KG (data from different sources may vary slightly).
