Masoneilan SVI™ FF Valve Positioner

Masoneilan 74000 Series Heavy Oil Process Valve

The base‑level 74000‑Series control valve adopts single‑stage trim within an angle‑style body, featuring simplified flow geometry for both valve body and trim. Its streamlined flow‑path design delivers proven reliability in heavy‑oil and harsh refining services with entrained solids, where complex conventional trims suffer catastrophic damage from high‑velocity erosive jets. Widely recognized across the industry and frequently name‑specified by experienced users, the 74000‑Series stands out as a differentiated solution with unique design and outstanding performance for the toughest process conditions.

Masoneilan 71000 Series Visbreaker Valve

Engineered with built‑in versatility, Masoneilan 71000‑Series single‑ported, heavy top‑guided control valves excel across numerous heavy‑duty process applications, including crude‑oil refining and gasifier units.

Masoneilan 72000 Series Large Mass Flow / Noise Reduction Valve

Built as a fabricated angle control valve, the Masoneilan 72000‑Series provides precise capacity control. Utilizing either single‑cage or multi‑cage trim, it efficiently reduces noise and outlet velocities within high‑capacity, high‑pressure‑letdown gas applications.

Masoneilan 49000 Series V-LOG™ Low-Noise Anti-Cavitation Valve

The 49000‑Series V‑LOG severe‑service control valve features an enlarged body cavity and stacked‑disk trim with up to 36 pressure‑reduction stages. Adopting Masoneilan’s proprietary V‑LOG trim technology, it is designed for high‑pressure‑drop working conditions prone to noise and cavitation, and offers reliable performance for a wide‑range of liquid and gas applications across process industries.

Masoneilan 73000 Series Sweep Angle Valve

The 73000‑Series control valve handles throttling service for highly erosive, flashing and two‑phase flows.

Masoneilan 12400 Series Digital Level Transmitter

Engineered for tank‑measurement duties, the 12400‑Series pneumatic level controllers provide both level control and transmission capability for tanks containing one fluid or a two‑fluid interface.

Masoneilan 12800 Series Pneumatic Level Transmitter / Controller

The 12800‑Series pneumatic level controllers control and/or transmit tank liquid level for single‑fluid and two‑fluid‑interface applications.

Masoneilan 75000 Series Tank Drain Sweep Angle Valve

The Masoneilan 75000‑Series is an erosion‑ and flashing‑resistant tank‑level control valve, specially designed for corrosive and viscous‑fluid level‑control applications in PTA chemical plants. Its full‑ported sweep‑angle body with contoured gallery reduces pressure loss and particle impingement erosion, while the high‑force‑actuated one‑piece plug‑stem with guiding fins shears crystalline deposits and throttles solid‑bearing flows; dual heavy‑duty guidance suppresses vibration and fatigue for extended severe‑service life. Available in 90°, 120° and 135° sweep‑angle variants, the valve simplifies piping installation within confined tank‑mounted spaces.

Masoneilan Masoneilan* 4700/4800 Corrosion Resistance Positioners

The Masoneilan 4700E/4800E electropneumatic and 4700P/4800P pneumatic positioners are proven control‑valve accessories. Their precision feedback‑cam design ensures accurate positioning, fast response and customizable control curves for rotary or reciprocating actuators. The cam can be fitted directly to rotary shafts, while a rugged lever‑turnbuckle assembly connects stem movement for linear actuators.

Masoneilan SVI™ II AP Advanced Performance Digital Valve Positioner (HART)

Equipped with a local interface, the Baker Hughes SVI™ II AP adopts a 32-bit microprocessor architecture, serving as a digital valve positioner to control pneumatic actuators through a two-wire 4-20mA signal.

Masoneilan SVI™ II ESD Emergency Shutdown Device

Capable of accepting 4‑20 mA, 0‑24 Vdc, or dual‑signal inputs, the Masoneilan SVI II ESD offers flexible signal‑based operation.
