KOSO EPA804-L10 Valve Positioner

KOSO EPA804-L10 Valve Positioner

Product Introduction

The KOSO EPA804-L10 Valve Positioner is a precision device designed for pneumatic actuator-operated control valves, converting a 4–20 mA DC input signal to air pressure for accurate valve positioning. With a maximum supply pressure of 120 psi (800 kPa), it ensures reliable operation in industrial processes. The positioner utilizes mechanical feedback from the valve stem to maintain precise alignment, making it ideal for both straight and angle travel valve applications.

Product Features

Precision Positioning Technology:

Converts 4–20 mA DC input signals to pneumatic pressure for valve actuation.

Valve stem feedback mechanism ensures accurate position tracking and minimal error.

High-Pressure Compatibility:

Maximum supply air pressure: 120 psi (800 kPa) for robust valve operation.

Application Versatility:

Angle Travel Series (Single Action): Suitable for rotary valves (e.g., ball, butterfly valves).

Compatible with dual-action actuators (requires model-specific configurations).

Wide Model Range:

Part of KOSO’s comprehensive positioner series, including:

Straight travel models (e.g., EPB801, EPC801) for linear valves.

Angle travel models (e.g., EPA804, EPC804) for rotary valves.

Reliable Industrial Design:

Engineered for continuous operation in process control systems.

Mechanical feedback system ensures stability in dynamic pressure environments.

Signal & Pressure Specifications:

Input signal: 4–20 mA DC (industry-standard for control systems).

Pressure output: Proportional to input signal, managed via internal pneumatic circuitry.
