The primary function is to regulate the volumetric flow rate of liquid or viscous coating materials, such as paints, adhesives, or protective coatings, to the application head or nozzle in a precision coating applicator system. This ensures consistent material delivery for uniform coating thickness and quality.
Key specifications include nominal diameter (DN15-DN50), flow coefficient (Cv 0.1-40), flow accuracy (±1.5%), operating pressure (1.0-1.6 MPa), maximum pressure (2.5 MPa), operating temperature (-20 to 80°C), response time (≤0.5 s), control signal (4-20 mA), supply voltage (24 V DC ±10%), body material (316L stainless steel), seal material (PTFE), weight (2.5-8.0 kg), and ingress protection (IP65). These are reference ranges and must be verified for the specific model.
The valve varies the cross-sectional area of the flow passage using a movable element (needle, ball, or gate) connected to an actuator. The actuator position, controlled manually or automatically, adjusts the orifice size, modulating flow resistance and thus the flow rate under system pressure.
The valve references standards such as ISO 6708 for nominal diameter, IEC 60534-2-3 for flow coefficient, ISO 10791-7 for flow accuracy, ISO 5211 for temperature, IEC 60534-4 for response time, IEC 60381-1 for control signal, IEC 61131-2 for supply voltage, ASTM A276 for body material, ASTM D4894 for seal material, and IEC 60529 for ingress protection. These are verification references and do not imply certification.
