At Hydraulics Online, we understand the importance of increasing the value of your brand and product range to outperform the competition at every turn. We can provide you with whatever level of support you need to ensure that your product is well-positioned in the marketplace… which is exactly why original equipment manufacturers return to us again and again, considering us a part of their product development team.

A long-standing customer, an original equipment manufacturer who produces new and reconditioned forklift truck attachments, contacted the technical team with a request to design a bespoke unit for a new application that would minimise a number of valves into one, single block.

The team were able to design the bespoke flow control valve to suit the needs of the customer and tailored it specifically to their application. The exact unit (pictured here) is a bespoke dual priority flow control valve: 3/4”, 120 litres/minute, complete with checks, 210 bar.

To quote the happy customer; “We approached Hydraulics Online 18 months ago for assistance in the design and supply of bespoke hydraulic control systems. As a result of their vast technical knowledge and wide product range available, we were able to develop a system which was both competitively priced and completely tailored to suit our application.

Since our initial projects with Hydraulics Online, we have worked together to develop further systems to complement our product range, further heightening our position in the market place. They have also been a valuable technical partner assisting our engineering personnel on site with issues faced in the field. Overall, a valuable tool for any business.”

Testimonial: Special Needs Charity - Scotland

We are a small charity that run boats on the Union and the Forth and Clyde canals for people with special needs. We needed the valve for our boat lift in our boathouse, the original unit burned out due to a faulty switch.

We really didn’t expect the unit until Monday, but received it on Saturday morning and had the lift working again in the afternoon!
