Masoneilan 78-40 Air Pressure Regulator Pressure Control Valve Masoneilan SVI2 Valve Positioner Supplier

The Masoneilan SVI II AP (Smart Valve Interface, Advanced Performance) Digital Valve Positioner is a cutting-edge solution for precise valve control in industrial automation. Powered by a 32-bit microprocessor, it uses a 4-20 mA control signal with HART communication to manage pneumatic actuators, offering seamless retrofitting for both Masoneilan and non-Masoneilan valves. Its non-contact position sensing technology and advanced diagnostics ensure long-term reliability and reduced process variability. With a robust, copper-free aluminum housing and certifications for hazardous areas (ATEX, IECEx), the SVI II AP is ideal for industries like oil and gas, power generation, and petrochemicals, delivering precision and efficiency.
