Electric single seat control valve
Electric single seat control valve
Product Overview | The Electric Single Seat Control Valve is a precision-engineered flow control device designed for applications requiring accurate regulation of pressure, temperature, or flow rate in liquid, gas, and steam systems. Featuring a single-seat globe valve design and electric actuator, it combines high shut-off capability with precise modulation, making it ideal for chemical processing, HVAC, and industrial automation. | |||||||||||||||
Applications | Process Industries: Precise control of corrosive chemicals, solvents, and process fluids. HVAC Systems: Temperature and pressure regulation in heating/cooling circuits. Water Treatment: Flow control in dosing systems and filtration units. Energy Systems: Steam flow management in power plants and boiler systems. | |||||||||||||||
Key Features | Electric Actuator: Control Signal: 4-20mA, 0-10V, or Modbus RTU communication for seamless integration with PLC/DCS. Positioning Accuracy: ±0.5% with smart PID algorithms. Power Supply: 24VDC, 110VAC, or 220VAC options. Single-Seat Design: Leakage Class: ANSI Class IV (FCI 70-2) or Class VI (zero leakage). Valve Plug & Seat: Hardened stainless steel (17-4PH/316L) for wear resistance. Flow Characteristics: Linear or Equal Percentage trim options for optimized process control. Cv Range: 0.01 to 450, adaptable to low or high flow rates. Durable Construction: Body Materials: Carbon steel (WCB), 316L stainless steel, or alloy steel (WC6). Seals: Graphite, PTFE, or Kalrez® for high-temperature/corrosive media. Safety & Compliance: Explosion-Proof: ATEX/IECEx certification available (Zone 1/2). Standards: IEC 60534, ANSI B16.34, ISO 5208. | |||||||||||||||
