The product range offered by Goodwin has now been extended to include a selection of high performance Axial Isolation and Control Valves.
Several years of Research, Design and Testing has been carried out to bring these products to market, with international patents pending for innovative design features.
Axial Isolation & Control Valves are used in highly demanding applications where tight shut off, high reliability, fast opening / closing and precise control are desired. Goodwin Axial Isolation & Control Valves represent a highly effective and cost efficient alternative to current designs available to the market.
Goodwin can supply a diverse range of forged or cast valve body materials, including a wide selection of Carbon Steel, Stainless Steel, Duplex Stainless Steel, Nickel Alloy and Titanium Alloy.
Reduced turbulence through the valve body as a result of the streamlined flow path.
High capacity, low noise and minimal pressure loss through the body.
Inherent manufacturing advantages compared to single piece body design
Flexible design allows the use of forgings or castings.
Full NDE accessibility for the pressure boundary components.
Advanced sealing and precise component manufacturing result in zero leakage.
Highly durable fast acting and precise.
Zero risk of gear teeth seizure even in low or non lubricated service.
Low friction and high efficiency compared to sliding gear mechanisms.
Low backlash maintained over the lifetime of the product.

A Goodwin Axial Isolation Valve was supplied to Technical Valve Services Ltd. to access the valves fire safe performance. With Lloyds Register in attendance to witness and certify, a fire test was conducted in accordance with API 6FA. Engulfing the pressurised test valve in a 761°C flame environment for 30 minutes, the valve was subsequently verified for external and through seat leakage as per the standard. The valve was tested in both the preferred flow direction and the reverse direction. The same valve passed both fire tests with ease without any need to adjust or replace any of the valve components or soft seals between tests.
The Goodwin Isolation valve performed well in the fire test against standard API 6FA:2011; no leakage occurred during testing in the operational direction. While it is not required by the standard, the valve was also tested against the operational direction. In this test during a burn of 1.5% of the allowable amount, the valve had absolute minimal leakage demonstrating excellent capability. The easy operation of the valve after testing showed a good fire test design.
We specialise in heavy precision, complex milling and turning and in particular with exotic materials such as Duplex and Inconel, as well as the standard materials such as carbon steel and stainless steel.
Through sustained investment in our people, facility and markets, our Company is a world leader in its technologies on a global basis, and does so whilst providing exemplary customer service. We specialise in heavy precision engineering incorporating all engineering activities and with our extensive capacity we are able to handle components up to 100,000kg which enables us to provide a one-stop shop whether you require a "build to print" or more in depth service. We have a workshop with modern and highly sophisticated machine tools.
In addition, Goodwin International working through the notified body BSI is PED 97/23/EC accredited. Goodwin supplies its valves in compliance with PED 2014/68/EU for the EEA or to meet customer requirements when specified.
Compliance with ATEX 2014/34/EU is by self declaration and a technical file is lodged and filed securely by an independent notified body (SIRA).
Traceability is the core of all Goodwin's quality systems. Every valve manufactured is traceable to source of material, NDE, pressure test and other test results unique to each individual valve. Our policy is that every valve is tested to contractual and API requirements NOT sample testing of randomly selected valves. This traceability policy is endemic to every employee involved in the manufacturing cycle of the valve.
Goodwin International has always subscribed to manufacturing product to the highest possible quality. Goodwin has held quality registration by British Standards Institute (BSI) since 1984, originally to BS5750 and developed through the years to now be compliant with ISO 9001:2008.
