Masoneilan Pressure Regulators – Reliable Industrial Pressure Control with Fluid Tech

Serving the Vaal Triangle & Free State with expert Masoneilan regulator supply and support

Baker Hughes’ Masoneilan pressure regulators are designed to keep fluid systems at a steady pressure without needing outside power. These devices are commonly used in industrial processes where reliable performance and ease of use are important to control the pressure of steam, gas, or liquid. Fluid Tech is a trusted supplier of Masoneilan regulators in the Vaal Triangle and Free State. We have the full range of products and can help you choose the best one for your needs.

What Are Masoneilan Pressure Regulators?

Masoneilan pressure regulators are self-acting instruments that control pressure by using the energy of the flowing fluid itself. Each regulator comprises a valve body and an actuator, responding to changes in process pressures to open or close accordingly. Because they require no external power source, these regulators are compact, cost-effective and easy to install for immediate operation.

These regulators are positioned between basic manual valves and more complex control loop systems in terms of performance and cost, offering reliable regulation without sophisticated control equipment.

Key Advantages of Masoneilan Pressure Regulators

Masoneilan regulators are chosen for many industrial systems due to features that help ensure dependable pressure control in demanding environments.

Self-powered operation eliminates the need for external electrical or pneumatic sources.
Compact and self-sufficient design allows quick installation.
Lower initial and operating costs compared with powered control valves.
Suitable for various media including steam, gas and liquids.
Available in multiple types to suit different regulatory needs.

Types of Masoneilan Pressure Regulators

Different regulator styles meet specific application needs, whether for pressure reduction, back-pressure control, or maintaining differential pressures.

173 Series – Back Pressure Regulator

The 173 Series are direct-operated back-pressure regulators designed to control or relieve upstream pressure. They are robust units available in similar size ranges as the 172 Series and feature several Cv options to ensure accurate performance.

Key attributes include:

Flow-to-close design
Several Cv ratings per size for fine regulation
Internal sensing standard, external on request
Compatibility with elastomeric or metal diaphragms
ATEX-compliant sealed construction where needed

These regulators excel where system pressure needs to be maintained above a set limit or safely relieved if it exceeds that limit.

174 Series – Reduced or Relief Regulator

The Masoneilan 174 Series provide flexibility for both pressure reducing and back-pressure relief functions within a compact and simple mechanical design. These units use a large diaphragm area to deliver accurate control even at low pressure settings, with flexible body orientations for installation ease.

Salient points include:

Combines reducing and relief functions in one model
Flexible installation orientation
Simple construction facilitating easy maintenance
Available in smaller size ranges, ideal for moderate pressure applications

525-526 Series – Advanced Pressure Regulators

The Masoneilan 525-526 Series are heavy-duty pressure reducing, back-pressure and differential pressure regulators designed for more demanding process applications. These units feature guided plugs with robust trim options to handle high pressure drops with minimal recovery, making them suitable for heavier industrial uses.

Key features include:

Heavy-duty top and bottom guided plug design
High capacity with low pressure recovery
Reduced capacity trims to manage flow characteristics
Options for flanged, butt-welded or screwed connections
Designed for use with 10900 Series actuators

This series is apt for facilities where pressure control stability and reliability under tougher conditions are paramount.
