Common Types of Valves and Their Features
Butterfly Valve Working Principle: A butterfly valve uses a disc to control the flow of fluids or gases. The disc is mounted on a shaft, and when the handle is turned, the disc rotates 90 degrees to allow or block the flow. Features: Simple structure, compact size, low flow resistance, commonly used in large flow […]
Enclosure Protection Ratings (UL, CSA, NEMA)
The protection ratings for enclosures defined by UL, CSA, and NEMA are categorized as follows. While the classifications are generally similar, there are minor differences in the details, so it is advisable to refer to the specific standards for more precise information. Type Classification Definition 1 General For indoor use, providing protection for enclosed components […]
Actuator IP Dust and Water Protection Rating
IP Protection Rating DefinitionThe IP (Ingress Protection) rating defines the protection level of a product’s enclosure against the intrusion of solid objects (such as tools, fingers, dust, etc.) and the ingress of water (from condensation, washing, immersion, etc.). The two digits following “IP” indicate the protection levels for solid objects and water intrusion. The first […]
How Actuators with Bus Functions Work – Modbus, CAN, Ethernet, Profibus
When you install a DCL electric control valve with bus functionality on a pipeline, you can control a set of electric control valves through the bus (Modbus, CAN, Ethernet, Profibus) to achieve synchronized control of the valve cluster. The control system communicates with the actuator via a bus communication protocol, sending commands to control the […]
