SPV-1 Servo Pressure Valve

Product catalog summary

Overview
The SPV-1 Servo Pressure Valve is a highly accurate and linear pressure regulating device designed for extrusion lines requiring precise pressure control. It features electronic closed-loop control for continuous monitoring and rapid adjustments, suitable for both static processes and those requiring airflow.

Key Features

Pressure setpoint and output with remote touch increase/decrease functionality.
Setpoint adjustment via a menu operator knob.
Filtered remote mode with an averaging function to prevent pressure overshoot.
Local and remote operation modes available.

Highly accurate and linear pressure regulating device SPV-1 a sophisticated regulating device designed for extrusion lines that necessitate precise pressure control. It continuously monitors output pressure and delivers rapid, accurate adjustments via electronic closed-loop control, making it ideal for both static processes and those requiring airflow. Filtered remote • Operates similarly to remote mode, with the addition of an averaging function to the input signal. This feature slows the response time, which can be beneficial in preventing the pressure from overshooting during significant adjustments. Operation and Installation modes Local mode • The pressure is manually controlled by the user through the front turning knob. Remote mode • The pressure is remotely controlled by a 0-10 VDC analogue input.
