Gap in the market
Boasting over 18,000m2 of warehousing, testing, and machining facilities to date across their UK site, RPV has continually invested during quieter periods, as well as expanding and taking on new product ranges. This continued improvement and investment in its extensive high-quality product ranges sets RPV aside from its competitors, the company states.
The continued growth of the company is also reflected in the opening of a brand new warehouse and office space over 1,000m2 in size, in Pasadena, Texas, servicing the US and Canadian markets as a stockist. In 2019, it was the right move for RPV to have stock on the ground in the USA, Robert Palmer says.
“We knew that there was a gap in the market for a stockist in the USA and since we have such a presence out there”, Palmer says. “It seemed like the logical progressive step that should be taken for us to be able to better respond and address the needs of our customers as we continue to expand our operations.”
Turbulent-free flow path
Focusing our attention on the non-slam axial flow valve, which is the latest addition in the Goodwin-assortment in RPV’s inventory, the non-slam axial style valve is a flanged solid disc valve fitted with CFD modeled streamlined internals. Its performance has been verified by physical testing.
The internals allow for a turbulent-free flow path around the disc and diffuser, which provides a high-pressure recovery, minimising the pressure drop across the valve.
A low-pressure drop can be associated with energy savings in plants, which makes the axial valve a green and competitive solution when considering full valve life cycle costs.
“Similar to the Goodwin International dual plate check valve, the Goodwin style axial flow check valve features a light-weight disc. Accompanied with a short stroke length, this ensures that the valve will respond quickly to a change in flow. The fast response ensures that reverse velocity cannot build and damage equipment”, states Steven Withers, Quality Assurance Director of RPV.
Lead time reduction
RPV states this valve is specifically used in applications where reliability and high performance are paramount. Its speed of response and dynamic behaviour prevents unwanted phenomena such as slam and water hammer from occurring, which in turn prevents damage to the system it is installed within.
“Having supplied to Robert for over two decades, we have seen first-hand his uncanny ability to predict what the market will need and have it stocked in his warehouses for when it has been required”, says Matthew Goodwin, Managing Director of Goodwin International. “By working with us and analysing historic sales, Robert knows what valves are out there are have been required globally and from this decided to become the first major global stockist of axial non-return valves. This will massively reduce lead times on what is typically a non-stock item helping our customers when they need rapid delivery and carving out yet another niche for RPV to excel at.”
Extra protection for critical applications
Due to the significance of the investment RPV made in Goodwin International’s axial check valves, it was written about as a notable item in the chairman’s statement of Goodwin PLC’s (Goodwin International’s parent company) annual report, which was released to the London Stock Exchange last August.
Increasingly, on critical system designs, it is necessary to have a redundant safety valve with a different failure mechanism.
“Having both the dual plate and axial valve products gives us the ability to meet customer requirements for dissimilar check valve products offering projects a fail-safe solution, a requirement which we are seeing more and more frequently”, says Sarah Mower, Sales Manager of RPV. “We have noticed the demand for installing dissimilar check valves has increased with some of the major key end-users who want to provide that extra protection for critical applications where the safeguarding of expensive equipment is paramount.”
The axial valves in RPV’s stock inventory can be specifically modified if required by the customer’s process conditions. RPV has the capability, knowledge, and expertise to review process conditions and adjust the valve dynamic response at their facility according to the data provided by the customer.
RPV has also completed an official training programme by Goodwin International to analyse the flow conditions utilising Goodwin International proprietary software. They have trained engineers ready to adjust a valve as necessary, which allows RPV to address various process flow conditions on an ex-stock basis. By doing so, RPV can ensure a valve operates at its optimum performance level, reducing pressure drop and increasing the longevity of the valve.
