Dresser Masoneilan SVI* (Smart Valve Interface, Advanced Performance) is a 32 bit microprocessor digital valve positioner with a local interface that control a pneumatic actuator using a two-wire 4-20 mA or Foundation fieldbus signal. The instrument offers modular design for easy service and upgrading. Its universal design offers ease of retrofit in place of existing analog positioners on Masoneilan or non-Masoneilan pneumatic actuators, either single-acting or double-acting.

Principle of operation

Dresser Masoneilan SVI positioner controlls control valve or other device through their actuator position. Input signal is converted to pneumatic output affecting required actuator positioning.

Input signal can be either:
- analogue 4-20 mA + HART
- digital Foundation fieldbus signal
Applications

Positioners are widely used in process industries such as:
- chemical
- petrochemical
- power plants
- paper industry
- food industry
