Compact Male In-Line Check Valve

We encourage customers to discuss their hydraulic system requirements with us so that we can help them achieve the best solution for their system. Our sales and design teams can work with you throughout all stages of the development process from prototyping to delivery. Our in-house capabilities mean that we have control over all key stages of the manufacturing process so if you require a part that’s a bit different to standard we can help.

Here’s an example of how we recently worked with an OEM customer to agile manufacture a solution to meet their requirements.

OEM’s Problem

They have a three drive, three pump system where a check valve is used on the case port of each pump. The length of the check valve they had was too long and they ideally wanted the check valve to screw into the pump. They needed a compact male / male check valve that would fit into their system.

HSP’s Solution

We offered the customer a bespoke valve solution. HSP designed a male / male check valve with an 3/8″ BSP port (E type seal) to 3/8″ BSP line, with a 0.35 bar cracking pressure. This was sent to the customer as a STEP file for them to input into their system and check it was suitable. Standard components were utilised within the part assembly of the bespoke valve to keep costs down. Pricing was based on estimated annual demand and a sample was manufactured for the OEM to test. The sample was agile manufactured in days (not weeks) and we worked with the OEM on their new part approval process.

OEM Feedback

“I will say, that I know the team have been impressed with the speed of response and the assistance we’ve received from yourself and HSP, so your products will be at the forefront of our minds when similar requirements arise in the future.”

“It’s great to hear comments like this, especially during these uncertain times. We’re very proud of the service level we offer customers as a SME manufacturer and part of my job is letting people know (who may not have heard of HSP) that we can offer full support through the design and production process. We’re always looking to help hydraulic engineers on new projects but unfortunately we’re often mis-labelled as a hydraulic re-seller.”
