Marlborough Engineering Limited

High Performance Check Valves

Marlborough Engineering have developed a range of inovative valves for the oil and water industries. The company's engineering experience has delivered novel solutions and methods. In combination with onsite machining and testing, the company is able to offer lead times well below the industry standard for specialist project work.

Our range of high performance products includes twin plate check valves, spring loaded (poppet) valves, and short pattern swing check valves. We manufacture in Aluminium Bronze, Super Duplex, Monel, Stellite, LCC, WCB, and Stainless Steel. New products and materials are constantly being added, contact us with your specific requirements.

The company is fully compliant with the Pressure Equipment Directive and has the facilities and knowledge to test the performance of valves in all key areas.

All Marlborough Engineering valves are marketed under the established mpv brand.

Retainerless Wafer Check Valve

Our Twyn-Flo concept has reduced the number of parts contained within the bore of the retainerless valve therefore simplifying its construction.

In conjunction with Queen’s University Belfast and the Centre of Excellence for Integrated Aircraft Technology, a detailed flow study has been performed using Fluent™, the state-ofthe- art Computational Fluid Dynamics (CFD) flow simulation software. The results show an improvement in the valve coefficient of up to 20% over competitors’ valves.

Our Twyn-Flo Retainerless Valve provides the following features:

• Simplicity of installation and reduced number of parts
• Larger port size, which allows for increased flow
• Extended spring leg permits the plates to open and close without any damage to the seal face in either resilient or metal to metal valve configuration
• Twyn-Flo metal to metal flat seated design provides efficient sealing in accordance with API 598

SLC: Spring-Loaded Check Valve

MPV’s new concept in Sprung Disc Valves has an innovative disc guide assembly that allows for easier assembly and a special retaining ring that gives absolute security for all internal parts.

Applications include liquids, gases and vapours. Functions as gravity check, vacuum breaker, breather, pressure-maintaining valve, foot valve, and check valve. Particularly suited for low temperatures, aggressive fluids, and many other industrial applications.

Standard materials:

• Body: 316ss
• Disc: 316ss
• Spring retainer: 302 Spring St.
• Retaining ring: 302ss
• Spring: Inconel 600

Other materials are available on request.

SPC: Short Pattern Check Valve

MPV’s Short Pattern Check Valves has been meticulously designed to be as simple in both construction and operation as possible; consequently these valves have been reduced to only 2 parts. The body is a one-piece design that has no leak paths and the plate is kept in place by an angled slot and is mechanically secured so no additional parts are required.

Mainly for liquids. Functions as gravity check valve. Particularly suited for sludge in industrial processes.
