Masoneilan SVi1000 Digital Valve Positioner

Featuring HART®‑on‑4‑20 mA communication, the SVi1000 is ideally suited for control systems based on 4‑20 mA signalling.

Masoneilan 77000 Series Multi-Stage High Pressure Valve

The 77000‑Series multi‑stage expanding‑area control valve is primarily engineered for high‑pressure compressible‑fluid and two‑phase‑flow services. It efficiently suppresses erosion, vibration and high noise, making it ideal for high‑pressure, high‑temperature flashing hydrocarbon‑liquid applications. Typical services include hot‑high‑pressure separator control for hydroprocessing, offshore gas‑wellhead choke‑valve duty and high‑pressure gas letdown with entrained debris. >

Masoneilan 78400 / 18400 Series LincolnLog™ Anti Cavitation Valve

The Axial‑Flow LincolnLog trim adopts a tortuous‑path design to distribute pressure drop along the plug axis. Its axial throttling stages operate synchronously during plug travel to maintain constant staging ratios at every lift, controlling velocity and pressure drop to eliminate cavitation‑induced trim damage. Well‑suited for pump‑recirculation and high‑pressure liquid‑letdown services, this valve is an ideal choice for hydrotreater‑related applications.

Masoneilan 84000 Series SteamForm™ Steam Conditioning Valve

Masoneilan steam‑conditioning‑valve series integrates low‑noise trim and a patented water‑injection system for combined pressure‑temperature reduction service. Backed by 125+ years of pressure‑control experience and modern desuperheating technology, the SteamForm™ line offers highly‑efficient steam conditioning.

Masoneilan Model 4411 Electro-Pneumatic Transducer

Masoneilan 525-526 Series Pressure Reducing, Back Pressure & Differential Pressure Regulators

The Model 525 and 526 pressure regulators are engineered for pairing with the 10900‑Series spring‑diaphragm actuators, covering pressure‑reducing, back‑pressure and differential‑pressure control duties.

Masoneilan 535H-536H Pressure Regulator for Reducing, Back Pressure and Differential Service

Baker‑Hughes Masoneilan 535H and 536H pressure regulators provide accurate pressure reduction for air, liquids, saturated and superheated steam. Available in sizes ¾” through 2”, with full‑area or reduced trim, they are suited for small‑to‑medium flow applications requiring Class IV or VI shut‑off per IEC 60534‑4 / ANSI/FCI 70.2. For service temperatures above the diaphragm temperature limit, fit the actuator beneath the valve‑body centre‑line. A condensate barrier in the sensing line and actuator case protects the diaphragm. Alternative mounting requires an independent condensate‑barrier assembly. Contact the factory for additional information.

Masoneilan 172 Series Spring loaded, Direct Operated, Pressure Reducing Regulator

The Masoneilan 172‑Series spring‑loaded direct‑operated pressure‑reducing regulators provide reliable outlet‑pressure control. Available in ½”‑2” (DN15‑DN50), the valves support a wide variety of end connections. The bolted‑flange configuration enables custom face‑to‑face dimensions for easy replacement of legacy equipment. Compact and rugged, they perform well under severe service and feature simple installation and maintenance.

Masoneilan 173 Series Spring Loaded, Direct-Operated Back-Pressure Regulator

Masoneilan 173 Series direct‑acting spring regulators serve steam, gas and liquid applications for pressure relief and back‑pressure control. Available in ½”–2” (DN15–DN50), they ensure durable, continuous industrial service.

Masoneilan 174 Series Spring Loaded, Direct-Operated Reducing or Back-Pressure Regulator

The Masoneilan 174‑Series spring‑loaded direct‑operated regulators perform pressure‑reducing or pressure‑relief control for diverse industrial applications. Equipped with a large‑size diaphragm for precise low‑pressure regulation and a lever‑type mechanism for reliable tight shut‑off, they are offered in ½”‑1‑½” (DN15‑DN40) with a maximum inlet pressure of 145 psig (10 barg). Its simple‑design construction ensures flexible deployment, easy installation and maintenance.

Masoneilan 33000 Series Triple Offset Butterfly Valves

Baker Hughes Masoneilan 33000 triple offset butterfly valves adopt proprietary designs with metal-to-metal seats to realize bidirectional bubble-tight shutoff across broad temperature and pressure ranges, suitable for both on-off isolation and high-throttling modulating control with low friction.

Masoneilan Conventional Butterfly Control Valves

The 37002 Series MiniTork® II is a heavy-duty automatic throttling butterfly control valve featuring a unique concave disc that delivers low dynamic torque and stable bidirectional flow, alongside deflection-free transmission, triple shaft bearings and direct-mounted positioners for precise modulating performance.
